getOverridableMethods

public JMethod[] getOverridableMethods()

Description copied from class: JClassType

Iterates over the most-derived declaration of each unique overridable method available in the type hierarchy of the specified type, including those found in superclasses and superinterfaces. A method is overridable if it is not final and its accessibility is public, protected, or package protected. Deferred binding generators often need to generate method implementations; this method offers a convenient way to find candidate methods to implement. Note that the behavior does not match Class.getMethod(String, Class[]), which does not return the most derived method in some cases.

Specified by:

getOverridableMethods in class JClassType

Returns:

an array of JMethod objects representing overridable methods
