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() |

ConstraintDescriptors) are immutable.
- Parameters:
clazz

constraints are invalid.
<T> T unwrap(java.lang.Class<T> type)
ValidationException
is thrown.
type
- the class of the object to be returned.
ValidationException
