Method Detail

getName

public String getName()

Returns the name of the mixin.

Returns:

the name

getDeploymentModel

public int getDeploymentModel()

Returns the deployment model.

Returns:

the deployment model

invokeMixin

public Object invokeMixin(int methodIndex,
                          Object callingObject)
                   throws Throwable

Invokes the method with the index specified. Invoked by methods without any parameters (slight performance gain since we are saving us one array creation).

Parameters:

methodIndex - the method index

callingObject - a reference to the calling object

Returns:

the result from the invocation

Throws:

Throwable

invokeMixin

public Object invokeMixin(int methodIndex,
                          Object[] parameters,
                          Object callingObject)
                   throws Throwable

Invokes an introduced method with the index specified.

Parameters:

methodIndex - the method index

parameters - the parameters for the invocation

callingObject - a reference to the calling object

Returns:

the result from the invocation

Throws:

Throwable

getImplementationClassName

public String getImplementationClassName()

Returns the implementation class name for the mixin.

Returns:

the implementation class name for the mixin

swapImplementation

public void swapImplementation(String className)

Swaps the current introduction implementation.

Parameters:

className - the class name of the new implementation
