Examples of AbstractMemberMetaData

org.datanucleus.metadata.AbstractMemberMetaData
Abstract representation of MetaData for a field/property of a class/interface. The term "member" is used to represent either a field or a method(property). The term property is used to represent the name after cutting off any Java-beans style "get" prefix. This class is extended for fields (FieldMetaData) and properties (PropertyMetaData) to provide the explicit support for those components.
