Method Detail

merge

public DeltaAware merge(DeltaAware d)

Description copied from interface: Delta

Merge the current set of deltas with a given DeltaAware instance, and return a coherent and complete DeltaAware instance. Implementations should be able to deal with null values passed in, or values of a different type from the expected DeltaAware instance. Usually the approach would be to ignore what is passed in, create a new instance of the DeltaAware implementation that the current Delta implementation is written for, apply changes and pass it back.

Specified by:

merge in interface Delta

Parameters:

d - instance to merge with, or null if no merging is needed

Returns:

a fully coherent and usable instance of DeltaAware which may or may not be the same instance passed in

addOperation

public void addOperation(Operation o)

toString

public String toString()

Overrides:

toString in class Object

getChangeLogSize
