Method Summary

Modifier and Type	Method and Description
ConstraintDescriptor<?>	getConstraintDescriptor() Returns the constraint metadata reported to fail.
Object[]	getExecutableParameters() Returns an Object[] representing the constructor or method invocation arguments if the ConstraintViolation is returned after validating the method or constructor parameters.
Object	getExecutableReturnValue() Returns the return value of the constructor or method invocation if the ConstraintViolation is returned after validating the method or constructor return value.
Object	getInvalidValue() Returns the value failing to pass the constraint.
Object	getLeafBean() Returns: the bean instance the constraint is applied on if it is a bean constraint the bean instance hosting the property the constraint is applied on if it is a property constraint or a container element constraint hosted on a property null when the ConstraintViolation is returned after calling Validator.validateValue(Class, String, Object, Class[]) the object the method is executed on if it is a method parameter, cross-parameter or return value constraint or a container element constraint hosted on a method parameter or return value null if it is a constructor parameter or cross-parameter constraint or a container element constraint hosted on a constructor parameter the object the constructor has created if it is a constructor return value constraint
String	getMessage()
String	getMessageTemplate()
Path	getPropertyPath()
T	getRootBean() Returns the root bean being validated.
Class<T>	getRootBeanClass() Returns the class of the root bean being validated.
<U> U	unwrap(Class<U> type) Returns an instance of the specified type allowing access to provider-specific APIs.

Method Detail

getMessage

String getMessage()

Returns:

the interpolated error message for this constraint violation

getMessageTemplate

String getMessageTemplate()

Returns:

the non-interpolated error message for this constraint violation

getRootBean

T getRootBean()

Returns the root bean being validated. For method validation, returns the object the method is executed on.

Returns null when:

• the ConstraintViolation is returned after calling Validator.validateValue(Class, String, Object, Class[])
• the ConstraintViolation is returned after validating a constructor.

Returns:

the validated object, the object hosting the validated element or null

getRootBeanClass

Class<T> getRootBeanClass()

Returns the class of the root bean being validated. For method validation, this is the object class the method is executed on. For constructor validation, this is the class the constructor is declared on.

Returns:

the class of the root bean or of the object hosting the validated element

getLeafBean

Object getLeafBean()

Returns:

• the bean instance the constraint is applied on if it is a bean constraint
• the bean instance hosting the property the constraint is applied on if it is a property constraint or a container element constraint hosted on a property
• null when the ConstraintViolation is returned after calling Validator.validateValue(Class, String, Object, Class[])
• the object the method is executed on if it is a method parameter, cross-parameter or return value constraint or a container element constraint hosted on a method parameter or return value
• null if it is a constructor parameter or cross-parameter constraint or a container element constraint hosted on a constructor parameter
• the object the constructor has created if it is a constructor return value constraint

Returns:

the leaf bean

getExecutableParameters

Object[] getExecutableParameters()

Returns an Object[] representing the constructor or method invocation arguments if the ConstraintViolation is returned after validating the method or constructor parameters. Returns null otherwise.

Returns:

parameters of the method or constructor invocation or null

Since:

1.1

getExecutableReturnValue

Object getExecutableReturnValue()

Returns the return value of the constructor or method invocation if the ConstraintViolation is returned after validating the method or constructor return value.

Returns null if the method has no return value. Returns null otherwise.

Returns:

the method or constructor return value or null

Since:

1.1

getPropertyPath

Path getPropertyPath()

Returns:

the property path to the value from rootBean

getInvalidValue

Object getInvalidValue()

Returns the value failing to pass the constraint. For cross-parameter constraints, an Object[] representing the method invocation arguments is returned.

Returns:

the value failing to pass the constraint

getConstraintDescriptor

ConstraintDescriptor<?> getConstraintDescriptor()

Returns the constraint metadata reported to fail. The returned instance is immutable.

Returns:

constraint metadata

unwrap

<U> U unwrap(Class<U> type)

Returns an instance of the specified type allowing access to provider-specific APIs. If the Bean Validation provider implementation does not support the specified class, ValidationException is thrown.

Type Parameters:

U - the type of the object to be returned

Parameters:

type - the class of the object to be returned

Returns:

an instance of the specified class

Throws:

ValidationException - if the provider does not support the call

Since:

1.1
