Method Detail

addNewInstanceMethod

public void addNewInstanceMethod(Method method)

Description copied from class: MetaClass

adds a new instance method to this meta class. Instance methods are able to overwrite the original methods of the class. Calling this method should not be done after initlise was called.

Specified by:

addNewInstanceMethod in class MetaClass

Parameters:

method - the method to be added

addNewStaticMethod

public void addNewStaticMethod(Method method)

Description copied from class: MetaClass

adds a new static method to this meta class. This is only possible as long as initilise was not called.

Specified by:

addNewStaticMethod in class MetaClass

Parameters:

method - the method to be added

initialize

public void initialize()

Description copied from class: MetaClass

complete the initlialisation process. After this method is called no methods should be added to the meta class. Invocation of methods or access to fields/proeprties is forbidden unless this method is called. This method should contain any initialisation code, taking a longer time to complete. An example is the creation of the Reflector. It is suggested to synchronize this method.
