PropertyDescriptor	getConstraintsForProperty(java.lang.String propertyName) Return the property descriptor for a given property.
boolean	isBeanConstrained() Returns true if the bean involves validation: a constraint is hosted on the bean itself a constraint is hosted on one of the bean properties or a bean property is marked for cascade (@Valid)

Method Detail

isBeanConstrained

boolean isBeanConstrained()

Returns true if the bean involves validation:

• a constraint is hosted on the bean itself
• a constraint is hosted on one of the bean properties
• or a bean property is marked for cascade (@Valid)

Returns:

true if the bean involves validation, false otherwise.

getConstraintsForProperty

PropertyDescriptor getConstraintsForProperty(java.lang.String propertyName)

Return the property descriptor for a given property. Return null if the property does not exist or has no constraint nor is marked as cascaded (see getConstrainedProperties() )

The returned object (and associated objects including ConstraintDescriptors) are immutable.

Parameters:

propertyName - property evaludated

Returns:

the property descriptor for a given property.

getConstrainedProperties

java.util.Set<PropertyDescriptor> getConstrainedProperties()

Returns:

the property descriptors having at least one constraint defined or which are marked as cascaded (@Valid) or an empty set.
