Constructor Detail

InterfaceMakerback to summary
public InterfaceMaker()

Create a new InterfaceMaker. A new InterfaceMaker object should be used for each generated interface, and should not be shared across threads.

Method Detail

addback to summary
public void add(Signature sig, Type[] exceptions)

Add a method signature to the interface.

Parameters
sig:Signature

the method signature to add to the interface

exceptions:Type[]

an array of exception types to declare for the method

addback to summary
public void add(Method method)

Add a method signature to the interface. The method modifiers are ignored, since interface methods are by definition abstract and public.

Parameters
method:Method

the method to add to the interface

addback to summary
public void add(Class<T> clazz)

Add all the public methods in the specified class. Methods from superclasses are included, except for methods declared in the base Object class (e.g. getClass, equals, hashCode).

Parameters
clazz:Class<T>

the class containing the methods to add to the interface

createback to summary
public Class<T> create()

Create an interface using the current set of method signatures.
