Konstruktordetails

DateDataElement

public DateDataElement(String name,
 Date value)

Creates a new modifiable instance without a validator.

Parameter:

name - The name of this element

value - The value of this element

DateDataElement

public DateDataElement(String name,
 Date value,
 Validator<? super Date> validator,
 Set<DataElement.Flag> flags)

Creates a new instance with a certain initial value.

Parameter:

name - The element name

value - The initial value

validator - The validator for the date value or NULL for none

flags - The optional flags for this data element

Methodendetails

init

public static void init()

This method should be invoked to initialize the property name constants for de-serialization.

copy

public DateDataElement copy(DataElement.CopyMode mode,
 de.esoco.lib.property.PropertyName<?>... copyProperties)

Returns a copy of this data element that contains all or a subset of it's current state. Always copied are the name and flags. Never copied is the parent reference because upon copying typically a reference to a copied parent needs to be set. The further data the copy contains depends on the copy mode:

• DataElement.CopyMode.FULL: The copy contains all data (except the parent reference).
• DataElement.CopyMode.FLAT: like DataElement.CopyMode.FULL but without sub-ordinate data elements.
• DataElement.CopyMode.PROPERTIES: The copy contains only the properties but not the element value and attributes.
• DataElement.CopyMode.PLACEHOLDER: The copy contains only the element name to serve as a placeholder.

The copy instance is created by invoking DataElement.newInstance() which has the recommendation to overwrite the return type to the concrete subtype to prevent the need for casting by the invoking code. For the same reason it is recommended that subclasses also override this method with the concrete return type and cast the result of super.copy() to that type.

Setzt außer Kraft:

copy in Klasse DataElement<Date>

Parameter:

mode - The copy mode

copyProperties - An optional list of properties to copy. If not provided all properties will be copied (unless the mode is DataElement.CopyMode.PLACEHOLDER)

Gibt zurück:

The copied instance

getValue

public final Date getValue()

Returns the date value.

Angegeben von:

getValue in Klasse DataElement<Date>

Gibt zurück:

The element value

• DataElement.getValue()

newInstance

protected DateDataElement newInstance()

Returns a new instance of the respective data element sub-type on which it is invoked. This is needed for GWT which doesn't support reflection. Used by DataElement.copy(CopyMode, PropertyName...) for cloning an instance. Implementations should overwrite the return type with their concrete type to prevent the need for casting by the invoking code.

Angegeben von:

newInstance in Klasse DataElement<Date>

Gibt zurück:

The new instance

updateValue

protected void updateValue(Date newValue)

Beschreibung aus Klasse kopiert: DataElement

Updates the element value. Will be invoked by DataElement.setValue(Object) to store a new value after validation. If a subclass wants to reject certain values it should do so in the DataElement.isValidValue(Validator, Object) method. Subclasses that are always immutable should implement an assertion because if the element has been initialized correctly (validator = NULL) this method should then be reached.

Angegeben von:

updateValue in Klasse DataElement<Date>

Parameter:

newValue - The new value for this element
