All Implemented Interfaces:

OidRecord

class OidEntity

extends java.lang.Object

implements OidRecord

This class represents the object variable managed in the MIB file. It encapsulates the information including: name, data type, permission, and description of the object variable. Each OidEntity object is also a link list node that contains a references to its parent object variable and a list of child variables.
