Class BaseMatcher

java.lang.Object

Direct Known Subclasses:

BaseMatcher, BaseMatcher, BaseMatcher, BaseMatcher

public class BaseMatcher
extends Object

Super class for all generated matcher classes of a tdom model. A matcher enhances the visitor class as it is capable of identifying the class of the visitee dynamically. For this "double dispatch" is used.
(This is different than the strategy currently used in metatool umod, which implies less class loading.)

Method Details

action

protected void action(TypedPCData pcdata)

Semantic execution; can be overridden by the user when defining a particular visitor. Will always be called when a TypedPCData is reached when traversing the model instance. This default implementation does nothing.

match

public void match(Object o)

Generic entry point, can be called with any model instance which implements Visitable<V>, as defined in the generated model. (The type-safe entry points in the generated classes are prefarable, namely faster and less error-prone.)

Throws:

TypeCastException - if interface is not implemented.
