Deprecated.

This class is, apart from the rename, identical to the Vaadin 7 com.vaadin.ui.AbstractField. It is provided for compatibility and migration purposes. As of 8.0, new field implementations should extend the new AbstractField instead.

@Deprecated
public abstract class AbstractField<T>
extends AbstractLegacyComponent
implements Field<T>, Property.ReadOnlyStatusChangeListener, Property.ReadOnlyStatusChangeNotifier, Action.ShortcutNotifier

Abstract field component for implementing buffered property editors. The field may hold an internal value, or it may be connected to any data source that implements the Property interface. AbstractField implements that interface itself, too, so accessing the Property value represented by it is straightforward.

AbstractField also provides the Buffered interface for buffering the data source value. By default the Field is in write through-mode and #setWriteThrough(boolean)should be called to enable buffering.

The class also supports validators to make sure the value contained in the field is valid.

Since:

3.0

Returns:

true to hide the error indicator, false to use the normal logic to show it when there are errors

getType

public abstract Class<? extends T> getType()

Deprecated.

Returns the type of the Field. The methods getValue and setValue must be compatible with this type: one must be able to safely cast the value returned from getValue to the given type and pass any variable assignable to this type as an argument to setValue.

Specified by:

getType in interface Property<T>

Returns:

the type of the Field

isReadOnly

public boolean isReadOnly()

Deprecated.

The abstract field is read only also if the data source is in read only mode.

Specified by:

isReadOnly in interface Property<T>

Overrides:

isReadOnly in class AbstractLegacyComponent

Returns:

true if the component or any of its parents is in read-only mode, false if not.

See Also:

AbstractLegacyComponent.setReadOnly(boolean)

setReadOnly

public void setReadOnly(boolean readOnly)

Deprecated.

Changes the readonly state and throw read-only status change events.

Specified by:

setReadOnly in interface Property<T>

Overrides:

setReadOnly in class AbstractLegacyComponent

Parameters:

readOnly - a boolean value specifying whether the component is put read-only mode or not

See Also:

com.vaadin.ui.Component#setReadOnly(boolean)

isInvalidCommitted

public boolean isInvalidCommitted()

Deprecated.

Tests if the invalid data is committed to datasource.

Specified by:

isInvalidCommitted in interface BufferedValidatable

See Also:

BufferedValidatable.isInvalidCommitted()

setInvalidCommitted

public void setInvalidCommitted(boolean isCommitted)

Deprecated.

Sets if the invalid data should be committed to datasource.

Specified by:

setInvalidCommitted in interface BufferedValidatable

See Also:

BufferedValidatable.setInvalidCommitted(boolean)

commit

public void commit()
            throws Buffered.SourceException,
                   Validator.InvalidValueException

Deprecated.

Description copied from interface: Buffered

Updates all changes since the previous commit to the data source. The value stored in the object will always be updated into the data source when commit is called.

Specified by:

commit in interface Buffered

Throws:

Buffered.SourceException - if the operation fails because of an exception is thrown by the data source. The cause is included in the exception.

Validator.InvalidValueException - if the operation fails because validation is enabled and the values do not validate

discard

public void discard()
             throws Buffered.SourceException

Deprecated.

Description copied from interface: Buffered

Discards all changes since last commit. The object updates its value from the data source.

Specified by:

discard in interface Buffered

Throws:

Buffered.SourceException - if the operation fails because of an exception is thrown by the data source. The cause is included in the exception.

isModified

public boolean isModified()

Deprecated.

Description copied from interface: Buffered

Tests if the value stored in the object has been modified since it was last updated from the data source.

Specified by:

isModified in interface Buffered

Returns:

true if the value in the object has been modified since the last data source update, false if not.

setBuffered

public void setBuffered(boolean buffered)

Deprecated.

Sets the buffered mode of this Field.

When the field is in buffered mode, changes will not be committed to the property data source until commit() is called.

Setting buffered mode from true to false will commit any pending changes.

Specified by:

setBuffered in interface Buffered

Parameters:

buffered - true if buffered mode should be turned on, false otherwise

Since:

7.0.0

isBuffered

public boolean isBuffered()

Deprecated.

Checks the buffered mode of this Field.

Specified by:

isBuffered in interface Buffered

Returns:

true if buffered mode is on, false otherwise

getValue

public T getValue()

Deprecated.

Gets the current value of the field.

This is the visible, modified and possible invalid value the user have entered to the field.

Note that the object returned is compatible with getType(). For example, if the type is String, this returns Strings even when the underlying datasource is of some other type. In order to access the converted value, use getConvertedValue() and to access the value of the property data source, use Property.getValue() for the property data source.

Since Vaadin 7.0, no implicit conversions between other data types and String are performed, but a converter is used if set.

Specified by:

getValue in interface Property<T>

Returns:

the current value of the field.

setValue

public void setValue(T newFieldValue)
              throws Property.ReadOnlyException,
                     Converter.ConversionException

Deprecated.

Sets the value of the field.

Specified by:

setValue in interface Property<T>

Parameters:

newFieldValue - the New value of the field.

Throws:

Property.ReadOnlyException

Converter.ConversionException

setValue

protected void setValue(T newFieldValue,
                        boolean repaintIsNotNeeded)

Deprecated.

Sets the value of the field.

Parameters:

newFieldValue - the New value of the field.

repaintIsNotNeeded - True if caller is sure that repaint is not needed.

Throws:

Property.ReadOnlyException

Converter.ConversionException

Validator.InvalidValueException

setValue

protected void setValue(T newFieldValue,
                        boolean repaintIsNotNeeded,
                        boolean ignoreReadOnly)
                 throws Property.ReadOnlyException,
                        Converter.ConversionException,
                        Validator.InvalidValueException

Deprecated.

Sets the value of the field.

Parameters:

newFieldValue - the New value of the field.

repaintIsNotNeeded - True if caller is sure that repaint is not needed.

ignoreReadOnly - True if the read-only check should be ignored

Throws:

Property.ReadOnlyException

Converter.ConversionException

Validator.InvalidValueException

Since:

7.5.7

getPropertyDataSource

public Property getPropertyDataSource()

Deprecated.

Gets the current data source of the field, if any.

Specified by:

getPropertyDataSource in interface Property.Viewer

Returns:

the current data source as a Property, or null if none defined.

setPropertyDataSource

public void setPropertyDataSource(Property newDataSource)

Deprecated.

Sets the specified Property as the data source for the field. All uncommitted changes are replaced with a value from the new data source.

If the datasource has any validators, the same validators are added to the field. Because the default behavior of the field is to allow invalid values, but not to allow committing them, this only adds visual error messages to fields and do not allow committing them as long as the value is invalid. After the value is valid, the error message is not shown and the commit can be done normally.

If the data source implements Property.ValueChangeNotifier and/or Property.ReadOnlyStatusChangeNotifier, the field registers itself as a listener and updates itself according to the events it receives. To avoid memory leaks caused by references to a field no longer in use, the listener registrations are removed on detach and re-added on attach.

Note: before 6.5 we actually called discard() method in the beginning of the method. This was removed to simplify implementation, avoid excess calls to backing property and to avoid odd value change events that were previously fired (developer expects 0-1 value change events if this method is called). Some complex field implementations might now need to override this method to do housekeeping similar to discard().

Specified by:

setPropertyDataSource in interface Property.Viewer

Parameters:

newDataSource - the new data source Property.

setConverter

public void setConverter(Class<?> datamodelType)

Deprecated.

Retrieves a converter for the field from the converter factory defined for the application. Clears the converter if no application reference is available or if the factory returns null.

Parameters:

datamodelType - The type of the data model that we want to be able to convert from

getModelType

protected Class<?> getModelType()

Deprecated.

Retrieves the type of the currently used data model. If the field has no data source then the model type of the converter is used.

Returns:

The type of the currently used data model or null if no data source or converter is set.

Since:

7.1

getConversionError

protected String getConversionError(Class<?> dataSourceType,
                                    Converter.ConversionException e)

Deprecated.

Returns the conversion error with {0} replaced by the data source type and {1} replaced by the exception (localized) message.

Parameters:

dataSourceType - the type of the data source

e - a conversion exception which can provide additional information

Returns:

The value conversion error string with parameters replaced.

Since:

7.1

getConvertedValue

public Object getConvertedValue()

Deprecated.

Returns the current value (as returned by getValue()) converted to the data source type.

This returns the same as getValue() if no converter has been set. The value is not necessarily the same as the data source value e.g. if the field is in buffered mode and has been modified.

Returns:

The converted value that is compatible with the data source type

setConvertedValue

public void setConvertedValue(Object value)

Deprecated.

Sets the value of the field using a value of the data source type. The value given is converted to the field type and then assigned to the field. This will update the property data source in the same way as when setValue(Object) is called.

Parameters:

value - The value to set. Must be the same type as the data source.

addValidator

public void addValidator(Validator validator)

Deprecated.

Adds a new validator for the field's value. All validators added to a field are checked each time the its value changes.

Specified by:

addValidator in interface Validatable

Parameters:

validator - the new validator to be added.

getValidators

public Collection<Validator> getValidators()

Deprecated.

Gets the validators of the field.

Specified by:

getValidators in interface Validatable

Returns:

An unmodifiable collection that holds all validators for the field.

Deprecated.

Removes the validator from the field.

Specified by:

removeValidator in interface Validatable

Parameters:

validator - the validator to remove.

removeAllValidators

public void removeAllValidators()

Deprecated.

Removes all validators from the field.

Specified by:

removeAllValidators in interface Validatable

isValid

public boolean isValid()

Deprecated.

Tests the current value against registered validators if the field is not empty. If the field is empty it is considered valid if it is not required and invalid otherwise. Validators are never checked for empty fields. In most cases, validate() should be used instead of isValid() to also get the error message.

Specified by:

isValid in interface Validatable

Returns:

true if all registered validators claim that the current value is valid or if the field is empty and not required, false otherwise.

validate

public void validate()
              throws Validator.InvalidValueException

Deprecated.

Checks the validity of the Field. A field is invalid if it is set as required (using setRequired(boolean) and is empty, if one or several of the validators added to the field indicate it is invalid or if the value cannot be converted provided a converter has been set. The "required" validation is a built-in validation feature. If the field is required and empty this method throws an EmptyValueException with the error message set using setRequiredError(String).

Specified by:

validate in interface Validatable

Throws:

Validator.InvalidValueException - if the value is not valid

See Also:

Validatable.validate()

validate

protected void validate(T fieldValue)
                 throws Validator.InvalidValueException

Deprecated.

Validates that the given value pass the validators for the field.

This method does not check the requiredness of the field.

Parameters:

fieldValue - The value to check

Throws:

Validator.InvalidValueException - if one or several validators fail

isInvalidAllowed

public boolean isInvalidAllowed()

Deprecated.

Fields allow invalid values by default. In most cases this is wanted, because the field otherwise visually forget the user input immediately.

Specified by:

isInvalidAllowed in interface Validatable

Returns:

true if invalid values are allowed.

See Also:

Validatable.isInvalidAllowed()

setInvalidAllowed

public void setInvalidAllowed(boolean invalidAllowed)
                       throws UnsupportedOperationException

Deprecated.

Fields allow invalid values by default. In most cases this is wanted, because the field otherwise visually forget the user input immediately.

In common setting where the user wants to assure the correctness of the datasource, but allow temporarily invalid contents in the field, the user should add the validators to datasource, that should not allow invalid values. The validators are automatically copied to the field when the datasource is set.

Specified by:

setInvalidAllowed in interface Validatable

Throws:

UnsupportedOperationException - if the setInvalidAllowed is not supported.

See Also:

Validatable.setInvalidAllowed(boolean)

getErrorMessage

public ErrorMessage getErrorMessage()

Deprecated.

Error messages shown by the fields are composites of the error message thrown by the superclasses (that is the component error message), validation errors and buffered source errors.

Overrides:

getErrorMessage in class AbstractComponent

See Also:

AbstractComponent.getErrorMessage()
