Method Detail

process

DescriptorImpl process(ServiceLocator serviceLocator,
                       DescriptorImpl descriptorImpl)

This method can be used to alter the descriptor read in. It can also add descriptors, or remove the descriptor (by returning null). Any alterations made to the descriptor passed in will remain in effect.

Parameters:

serviceLocator - the ServiceLocator being populated. Will not be null

descriptorImpl - The descriptorImpl read from some external source. This processor can modify this descriptor fully

Returns:

The descriptor to be added to the system. If this returns null then the descriptorImpl passed in will NOT be added to the system. Implementations may return the descriptor passed in, but do not have to. The descriptor added to the system will be the one returned from this method
