org.eclipse.equinox.internal.p2.metadata.expression.Expression

org.eclipse.equinox.internal.p2.metadata.expression.Unary

org.eclipse.equinox.internal.p2.metadata.expression.Member

All Implemented Interfaces:

java.lang.Comparable<Expression>, IExpressionConstants, IExpression

Direct Known Subclasses:

Member.DynamicMember, Member.LengthMember

public abstract class Member
extends Unary

An expression that performs member calls to obtain some value from some object instance. It uses standard bean semantics so that an attempt to obtain "value" will cause an attempt to call getValue() and if no such method exists, isValue() and if that doesn't work either, value().
