stop
Type: Stimulsoft.Data.Expressions.Antlr.RuntimeIToken

Return Value

Type: Object

[Missing <returns> documentation for "M:Stimulsoft.Data.Expressions.Antlr.Runtime.Tree.BaseTreeAdaptor.ErrorNode(Stimulsoft.Data.Expressions.Antlr.Runtime.ITokenStream,Stimulsoft.Data.Expressions.Antlr.Runtime.IToken,Stimulsoft.Data.Expressions.Antlr.Runtime.IToken,Stimulsoft.Data.Expressions.Antlr.Runtime.RecognitionException)"]

Implements

ITreeAdaptorErrorNode(ITokenStream, IToken, IToken, RecognitionException)
Remarks
If you specify your own kind of tree nodes, you will likely have to override this method. CommonTree returns Token.INVALID_TOKEN_TYPE if no token payload but you might have to set token type for diff node type. You don't have to subclass CommonErrorNode; you will likely need to subclass your own tree node class to avoid class cast exception.
