Property :: isTransient - Is property transient

Attributes as well as references might be defined implicitly or explicitly as transient properties. Transient properties contain information, which is available during the life time of the process, only. Attributes in transient instances automatically (implicit) become transient, also when not being defined as transient attributes in the property definition.

The property returns true , when it refers to a transient attribute or collection and false otherwise. The property throws an exception, when the property handle is not valid.

For transient references, the result of the function depends on the property handle currently set in the transient property ( setTransientProperty() ). In order to check, whether a property handle refers to a property defined as transient property or not, one may call propertyDefinition().isTransientAttribute() or propertyDefinition().isTransientReference() .
