Class BaseLeftInheritanceTuple

java.lang.Object

tools.refinery.interpreter.matchers.tuple.AbstractTuple

tools.refinery.interpreter.matchers.tuple.Tuple

tools.refinery.interpreter.matchers.tuple.BaseLeftInheritanceTuple

All Implemented Interfaces:

ITuple

Direct Known Subclasses:

LeftInheritanceTuple, LeftInheritanceTuple1, LeftInheritanceTuple2, LeftInheritanceTuple3, LeftInheritanceTuple4

public abstract class BaseLeftInheritanceTuple
extends Tuple

Common functionality of left inheritance tuple implementations.

Left inheritance tuples inherit their first few elements from another tuple, and extend it with additional "local" elements.

Since:

1.7
