Constructor Detail

ValidatorImpl

public ValidatorImpl()

Default constructor. Builds a default validator factory, if available and creates the validator. Returns an Exception if a Validator could not be created.

ValidatorImpl

public ValidatorImpl(Configuration conf)

ValidatorImpl

public ValidatorImpl(jakarta.validation.ValidatorFactory validatorFactory,
                     jakarta.persistence.ValidationMode mode)

Type-specific constructor Returns an Exception if a Validator could not be created.

Parameters:

validatorFactory - Instance of validator factory to use. Specify null to use the default factory.

mode - ValdiationMode enum value

Method Detail

addValidationGroup

public void addValidationGroup(String validationGroupName,
                               Class<?>... vgs)

Add a validation group for the specific property. The properties map to a specific lifecycle event. To disable validation for a group, set the validation group to null.

Parameters:

validationGroupName -

vgs -

addValidationGroup

public void addValidationGroup(Integer event,
                               Class<?>... validationGroup)

Add a validation group for a specified event. Event definitions are defined in LifecycleEvent. To disable validation for a group, set the validation group to null.

Parameters:

event -

validationGroup -

addValidationGroup

public void addValidationGroup(String validationGroupName,
                               String group)

Add the validation group(s) for the specified event. Event definitions are defined in LifecycleEvent

Parameters:

event -

group -

getValidationGroup

public Class<?>[] getValidationGroup(Integer event)

Return the validation groups to be validated for a specified event

Parameters:

event - Lifecycle event id

Returns:

An array of validation groups

isValidating

public boolean isValidating(Integer event)

Returns whether the Validator is validating for the specified event. Based on whether validation groups are specified for the event.

Parameters:

event - the event to check for validation

Returns:

returns true if validating for this particular event

getConstraintsForClass

public jakarta.validation.metadata.BeanDescriptor getConstraintsForClass(Class<?> cls)

Returns the validation constraints for the specified class

Parameters:

cls - Class for which constraints to return

Returns:

The validation bean descriptor

validate
