Method Summary

void	extract(MethodInfoStructure methodInfo, Dna srcDna, DisconnectedMethod disconnectedMethod) This method copies into the disconnectMethod instance provided as parameter the methodInfo object.

Method Detail

extract

void extract(MethodInfoStructure methodInfo,
             Dna srcDna,
             DisconnectedMethod disconnectedMethod)
             throws DisconnectionFailedException

This method copies into the disconnectMethod instance provided as parameter the methodInfo object. Actually this is a real copy, that is the source methodInfo gets cloned and all its references to cp_infos entries are correctly updated.
What this means is that the copy of a method from a source Dna to a target DisconnectMethod data structure entails that a deep copy of all the referenced cp_infos will be launched. This is a required step to bring into the target DisconnectedMethod all the other information on which the method definition is based.

Note: if using a stateful deep copier it is fundamental to perform all the deep copy invocations by means of the same DeepCopier instance.

Parameters:

methodInfo - The reference to the method to be copied into the target disconnectMethod

srcDna - The Dna instance the methodInfo belongs to

disconnectMethod - The target DisconnectedMethod instance in which the disconnected method will be stored for a subsequent injection

Throws:

DisconnectionFailedException
