Interface MutationVisitor

public interface MutationVisitor

A visitor for mutations.

This is not an entirely traditional visitor; many of the visitable classes have inheritance relationships with each other. The purpose of this visitor is primarily to support specialization where it is useful while still providing a generic visitation pattern otherwise.

Method Detail

visit

void visit(Mutation m)
           throws MutationException

Visit a mutation.

Parameters:

m - Mutation to visit.

Throws:

MutationException

visit

void visit(MutationGroup mg,
           boolean begin)
           throws MutationException

Visit a mutation group.

Parameters:

mg - Mutation group to visit.

begin - Used to indicate to this visitor whether this is the beginning of the visitation. Since a mutation group encapsulates other mutations, some visitors may want to execute setup actions before visitation of member mutations begins. If the mutation group visits its members (see MutationGroup.visitMembers(boolean)), this method will be called with this parameter set to false after all the member mutations have been visited.

Throws:

MutationException

void visit(GroupableMutation gm)
           throws MutationException

Visit a groupable mutation.

Parameters:

gm - Groupable mutation to visit.

Throws:
