- All Implemented Interfaces:
- KeyFilteredNamingContext, PNameCoder, PNameManager, PNamingContext
- public class LongIdPNC
- extends AbstractInheritKeyFilteredPNamingContext
Is a PNamingContext managing the LongIdPName and LongIdBinder. It is based
on the AbstractInheritKeyFilteredPNamingContext class. The key is the class
identifier. The filter (evaluate method) is in charge to extract the class
identifier from the identifier (long value). Indeed the long value is
composed of two parts the high bits describe the class identifier, whereas
the low bits describes the object instance identifier. The limit between both
parts are defined are building time (constructor).
