Interface Factory

public interface Factory

All enhanced instances returned by the Enhancer class implement this interface. Using this interface for new instances is faster than going through the Enhancer interface or using reflection. In addition, to intercept methods called during object construction you must use these methods instead of reflection.

Method Detail

newInstance

java.lang.Object newInstance(Callback callback)

Creates new instance of the same type, using the no-arg constructor. The class of this object must have been created using a single Callback type. If multiple callbacks are required an exception will be thrown.

Parameters:

callback - the new interceptor to use

Returns:

new instance of the same type

newInstance

java.lang.Object newInstance(Callback[] callbacks)

Creates new instance of the same type, using the no-arg constructor.

Parameters:

callbacks - the new callbacks(s) to use

Returns:

new instance of the same type

newInstance

java.lang.Object newInstance(java.lang.Class[] types,
                             java.lang.Object[] args,
                             Callback[] callbacks)

Creates a new instance of the same type, using the constructor matching the given signature.

Parameters:

types - the constructor argument types

args - the constructor arguments

callbacks - the new interceptor(s) to use

Returns:

new instance of the same type

getCallback

Callback getCallback(int index)

Return the Callback implementation at the specified index.

Parameters:

index - the callback index

Returns:

the callback implementation

setCallback

void setCallback(int index,
                 Callback callback)

Set the callback for this object for the given type.

Parameters:

index - the callback index to replace

callback - the new callback

setCallbacks

void setCallbacks(Callback[] callbacks)

Replace all of the callbacks for this object at once.

Parameters:

callbacks - the new callbacks(s) to use

getCallbacks

Callback[] getCallbacks()

Get the current set of callbacks for ths object.

Returns:

a new array instance
