org.eclipse.jdt.core.dom.IBinding
A binding represents a named entity in the Java language. The world of bindings provides an integrated picture of the structure of the program as seen from the compiler's point of view. This interface declares protocols common to the various different kinds of named entities in the Java language: packages, types, fields, methods, constructors, local variables, and annotations. @see IPackageBinding @see ITypeBinding @see IVariableBinding @see IMethodBinding @see IAnnotationBinding @see IMemberValuePairBinding @since 2.0 @noimplement This interface is not intended to be implemented by clients.
