Symbol VarLabel
bool VarIsList
Func< LNode, LNodeResultSaver
 A function that saves the result produced by the matching code of this predicate (null if the result is not saved). For example, if the parser generator is given the predicate @[ x='a'..'z' ], the default matching code will be @(Match('a', 'z')), and ResultSaver will be set to a function that receives this matching code and returns @(x = Match('a', 'z')) in response.

 Pred (LNode basis)
LNode AutoSaveResult (LNode matchingCode)
virtual Pred Clone ()
 Deep-clones a predicate tree. Terminal sets and Nodes referenced by the tree are not cloned; the clone's value of Next will be null. The same Pred cannot appear in two places in a tree, so you must clone before re-use. More...
string ToStringWithPosition ()
virtual string ChooseGotoLabel ()
 Optional. If this predicate represents the matching code for a branch of an Alts and this code is reached through a goto statement, this method is used to select a label name. Supported by RuleRef. More...
