Class AbstractMetaData

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

EvaluatorMetaData, EventTypeMetaData, ImplClassMetaData, ResourceMetaData, ToolAgentMetaData

public abstract class AbstractMetaData

extends java.lang.Object

implements java.io.Serializable

An abstract base class for meta-data implementations. The meta-data supports a kind of inheritance; repository entries can reference a parent type (by id) via their 'type' attribute. Property accessor methods automatically return the parent property value if the child value is null. N.B. subclasses' property getters are expected to conform to this pattern.
