java.lang.Object org.jboss.dna.jcr.PropertyDefinitionId
@Immutable public final class PropertyDefinitionId
An immutable identifier for a property definition. Although instances can be serialized, the property definitions are often
stored within the graph as string values
on a property. These string values can later be
parsed
to reconstruct the identifier. Note that this string representation does not
use namespace prefixes, so they are long-lasting and durable.
What distinguishes one property definition from another is not well documented in the JSR-170 specification. The closest this version of the spec gets is Section 6.7.15, but that merely says that more than one property definition can have the same name. The proposed draft of the JSR-283 specification does clarify this more: Section 4.7.15 says :
"A node type may have two or more property definitions with identical name attributes (the value returned by
ItemDefinition.getName) as long as the definitions are otherwise distinguishable by either the required type attribute (the
value returned by PropertyDefinition.getRequiredType) or the multiple attribute (the value returned by
PropertyDefinition.isMultiple)."
This class is Serializable
and designed to be used as a key in a HashMap
.
