public interface Validator
Validate bean instances. Implementations of this interface must be thread-safe.
| Method Summary | ||
|---|---|---|
BeanDescriptor |
getConstraintsForClass(java.lang.Class<?> clazz)
Return the descriptor object describing bean constraints. |
|
|
unwrap(java.lang.Class<T> type)
Return an instance of the specified type allowing access to provider-specific APIs. |
|
|
validate(T object,
java.lang.Class<?>... groups)
Validates all constraints on object. |
|
|
validateProperty(T object,
java.lang.String propertyName,
java.lang.Class<?>... groups)
Validates all constraints placed on the property of object
named propertyName. |
|
|
validateValue(java.lang.Class<T> beanType,
java.lang.String propertyName,
java.lang.Object value,
java.lang.Class<?>... groups)
Validates all constraints placed on the property named propertyName
of the class beanType would the property value be value
ConstraintViolation objects return null for
ConstraintViolation#getRootBean() and ConstraintViolation#getLeafBean() |

object - object to validategroups - group or list of groups targeted for validation
(default to Default)
java.lang.IllegalArgumentException - if object is null
or if null is passed to the varargs groups
ValidationException - if a non recoverable error happens
during the validation process
<T> java.util.Set<ConstraintViolation<T>> validateProperty(T object,
java.lang.String propertyName,
java.lang.Class<?>... groups)
object
named propertyName.
object - object to validatepropertyName - property to validate (ie field and getter constraints)groups - group or list of groups targeted for validation
(default to Default)
java.lang.IllegalArgumentException - if object is null,
if propertyName null, empty or not a valid object property
or if null is passed to the varargs groups
ValidationException - if a non recoverable error happens
during the validation process
<T> java.util.Set<ConstraintViolation<T>> validateValue(java.lang.Class<T> beanType,
java.lang.String propertyName,
java.lang.Object value,
java.lang.Class<?>... groups)

ConstraintViolation objects return null for
ConstraintViolation#getRootBean() and ConstraintViolation#getLeafBean()
beanType - the bean typepropertyName - property to validatevalue - property value to validategroups - group or list of groups targeted for validation
(default to Default)
java.lang.IllegalArgumentException - if beanType is null,
if propertyName null, empty or not a valid object property
or if null is passed to the varargs groups
ValidationException - if a non recoverable error happens
during the validation processBeanDescriptor getConstraintsForClass(java.lang.Class<?> clazz)
ConstraintDescriptors) are immutable.
- Parameters:
clazz - class or interface type evaluated
- Returns:
- the bean descriptor for the specified class.
- Throws:
java.lang.IllegalArgumentException - if clazz is null
ValidationException - if a non recoverable error happens
during the metadata discovery or if some
constraints are invalid.
<T> T unwrap(java.lang.Class<T> type)
ValidationException is thrown.
type - the class of the object to be returned.
ValidationException - if the provider does not support the call.
