Class PProduction.Continue

java.lang.Object

org.stekikun.dolmen.syntax.PProduction.Item

org.stekikun.dolmen.syntax.PProduction.Continue

Enclosing class:

PProduction

public static final class PProduction.Continue
extends PProduction.Item

Represents a continuation of the current rule, and unlike the equivalent actual, this allows the generator to produce an optimized tail-recursive call.
A continuation can only be used last in a production rule, and for now can only reenter the current rule with the same original arguments and parameters.
