Participants

• Strategy (Compositor)

• declares an interface common to all supported algorithms. Context uses this interface to call the algorithm defined by a ConcreteStrategy.
• ConcreteStrategy (SimpleCompositor, TeXCompositor, ArrayCompositor)

• implements the algorithm using the Strategy interface.
• Context (Composition)

• is configured with a ConcreteStrategy object.
• maintains a reference to a Strategy object.
• may define an interface that lets Strategy access its data.
