recursionEffect

public java.lang.String recursionEffect(java.lang.String entryName)

Description copied from interface: IProcessStep

The effect of this processing step if the JarProcessor was to recurse on this entry. Return null if this step will not do anything with this entry. Return the new entryName if this step will modify this entry on recursion.

Returns:

The new entry name, or null

preProcess
