Abstract

A plurality of actions are applied to a directed graph, where the directed graph has a plurality of nodes. A node in the directed graph is traversed to, and an specific method for each of the plurality of actions is performed on the traversed-node. The traversing and performing are repeated until all nodes in the directed graph have been traversed to. Only a single traversal of the directed graph need be performed to apply all of the actions to the directed graph. The plurality of the actions are in the form of a chain. Each action has an action object pointer, and the actions include a base action at a tail end of the chain and at least one chain action at a head end of the chain. The action object pointer of each chain action points to an immediately adjacent action toward the tail end of the chain, and the action object pointer of the base action points to the chain action at the head end of the chain.
