Examples of org.eclipse.jdt.core.dom.IVariableBinding

org.eclipse.jdt.core.dom.IVariableBinding
A variable binding represents either a field of a class or interface, or a local variable declaration (including formal parameters, local variables, and exception variables). @see ITypeBinding#getDeclaredFields() @since 2.0 @noimplement This interface is not intended to be implemented by clients.
