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.

Includes the type parameters. If called on a type parameter, does not include any bounds. For example, a type Foo declared in com.example would be given as "com.example.Foo", while the same type instantiated with Baz would be "com.example.Foo".

Specified by: getSimpleSourceName in interface JType Specified by: getSimpleSourceName in class JClassType getSubtypes public JArrayType[] getSubtypes() Description copied from class: JClassType Returns all subtypes for this type. This means various things: Array: subtypes are those array types with the same number of dimensions as this type, and whose base element type is a subtype of this type's element type. Wildcards: if ? extends X, subtypes are subtypes of X. If ? super X: no subtypes. Named type parameter: subtypes are (1) those subtypes of the "base" type that are assignable to this, plus (2) the first bound of the parameter, if the bound is both assignable to this and not an interface. The "base" is the type itself, except for delegating types, where the base is the result of getBaseType(). Real class: subtypes are those real classes that are subtypes of this class in the class hierarchy. Interfaces aren't subtypes of Object. Parameterized type: subtypes are those subtypes of the generic type of this type which can be parameterized with the right types so that they have this type as a supertype. The subtypes are parameterized as described, with minimal parameterization. Raw type: subtypes are the subtypes of the generic type of this type, as raw types if they themselves are generic.

Specified by: isClass in interface JType Specified by: isClass in class JClassType isDefaultInstantiable public boolean isDefaultInstantiable() Description copied from class: JClassType Determines if the class can be constructed using a simple new operation. Specifically, the class must be a class rather than an interface, have either no constructors or a parameterless constructor, and be a top-level class or a static nested class.
