Constructor Detail

Delegator

public Delegator(Class<I> anInterface)

Creates a Delegator<E> from the type interface.

Parameters:

anInterface - The interface to build references from.

Throws:

IllegalArgumentException - 'anInterface' must not be null.

IllegalArgumentException - 'anInterface' must be an interface type.

Method Detail

build

public I build(Class aTarget,
               String aMethodName)
        throws IllegalArgumentException,
               UnsupportedOperationException

Returns Dynamic Proxy that implements the target generic parameter interface. The implementing Dynamic Proxy executes the underlying method identified by Class type and Method name.

Parameters:

aTarget - non-null class with a bindable static method.

aMethodName - name of the static method.

Returns:

Dynamic proxy implementing the target generic interface.

Throws:

IllegalArgumentException - 'aTarget' must not be null.

UnsupportedOperationException - No suitable method found.

build

public I build(Object aTarget,
               String aMethodName)
        throws IllegalArgumentException,
               UnsupportedOperationException

Returns Dynamic Proxy that implements the target generic parameter interface. The implementing Dynamic Proxy executes the underlying method identified by Object instance and Method name.

Parameters:

aTarget - non-null target with a bindable method.

aMethodName - name of the method.

Returns:

Dynamic proxy implementing the target generic interface.

Throws:

IllegalArgumentException - 'aTarget' must not be null.

UnsupportedOperationException - No suitable method found.
