Class TypeDispatchedConstructor<T>

java.lang.Object

com.pervasive.datarush.types.TypeDispatchedConstructor<T>

Type Parameters:

T - the type of object constructed

All Implemented Interfaces:

TokenTypeDispatcher

Direct Known Subclasses:

TokenValueExtractor

public abstract class TypeDispatchedConstructor<T>
extends Object
implements TokenTypeDispatcher

A base class for type-driven object factories.

Default behavior is implemented for all types, making it necessary to only implement those methods applicable to types supported by the factory. The default implementation is to invoke an error handler method, handleUnsupportedType(TokenType), which must be implemented by derived classes.
