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

org.eclipse.jdt.core.dom.IMethodBinding
A method binding represents a method or constructor of a class or interface. Method bindings usually correspond directly to method or constructor declarations found in the source code. However, in certain cases of references to a generic method, the method binding may correspond to a copy of a generic method declaration with substitutions for the method's type parameters (for these, getTypeArguments returns a non-empty list, and either isParameterizedMethod or isRawMethod returns true). And in certain cases of references to a method declared in a generic type, the method binding may correspond to a copy of a method declaration with substitutions for the type's type parameters (for these, getTypeArguments returns an empty list, and both isParameterizedMethod and isRawMethod return false). @see ITypeBinding#getDeclaredMethods() @since 2.0 @noimplement This interface is not intended to be implemented by clients.
