binderStatuses - the validation results for binder level validation

Method Detail

createUnresolvedStatus

public static <BEAN> BinderValidationStatus<BEAN> createUnresolvedStatus(Binder<BEAN> source)

Convenience method for creating a unresolved validation status for the given binder.

In practice this status means that the values might not be valid, but validation errors should be hidden.

Type Parameters:

BEAN - the bean type of the binder

Parameters:

source - the source binder

Returns:

a unresolved validation status

isOk

public boolean isOk()

Gets whether validation for the binder passed or not.

Returns:

true if validation has passed, false if not

hasErrors

public boolean hasErrors()

Gets whether the validation for the binder failed or not.

Returns:

true if validation failed, false if validation passed

getBinder

public Binder<BEAN> getBinder()

Gets the source binder of the status.

Returns:

the source binder

getValidationErrors

public List<ValidationResult> getValidationErrors()

Gets both field and bean level validation errors.

Returns:

a list of all validation errors

getFieldValidationStatuses

public List<BindingValidationStatus<?>> getFieldValidationStatuses()

Gets the field level validation statuses.

The field level validtors have been added with Binder.BindingBuilder.withValidator(Validator).

Returns:

the field validation statuses

getBeanValidationResults

public List<ValidationResult> getBeanValidationResults()

Gets the bean level validation results.

Returns:

the bean level validation results

getFieldValidationErrors

public List<BindingValidationStatus<?>> getFieldValidationErrors()

Gets the failed field level validation statuses.

The field level validtors have been added with Binder.BindingBuilder.withValidator(Validator).

Returns:

a list of failed field level validation statuses

getBeanValidationErrors

public List<ValidationResult> getBeanValidationErrors()

Gets the failed bean level validation results.

Returns:

a list of failed bean level validation results

notifyBindingValidationStatusHandlers

public void notifyBindingValidationStatusHandlers()

Notifies all validation status handlers in bindings.

See Also:

notifyBindingValidationStatusHandlers(SerializablePredicate)

notifyBindingValidationStatusHandlers

public void notifyBindingValidationStatusHandlers(SerializablePredicate<BindingValidationStatus<?>> filter)

Notifies validation status handlers for bindings that pass given filter. The filter should return true for each BindingValidationStatus that should be delegated to the status handler in the binding.

Parameters:

filter - the filter to select bindings to run status handling for
