io.parsingdata.metal.expression.value.reference

Class Ref<T>

java.lang.Object

io.parsingdata.metal.expression.value.reference.Ref<T>

Type Parameters:

T - The type of reference to match on.

All Implemented Interfaces:

ValueExpression

Direct Known Subclasses:

Ref.DefinitionRef, Ref.NameRef

public class Ref<T>
extends Object
implements ValueExpression

A ValueExpression that represents all Values in the parse state that match a provided object. This class only has a private constructor and instead must be instantiated through one of its subclasses: Ref.NameRef (to match on name) and Ref.DefinitionRef (to match on definition). A limit argument may be provided to specify an upper bound to the amount of returned results.
