ruleIndex
Type: SystemInt32

[Missing <param name="ruleIndex"/> documentation for "M:Stimulsoft.Data.Expressions.Antlr.Runtime.BaseRecognizer.AlreadyParsedRule(Stimulsoft.Data.Expressions.Antlr.Runtime.IIntStream,System.Int32)"]

Return Value

Type: Boolean

[Missing <returns> documentation for "M:Stimulsoft.Data.Expressions.Antlr.Runtime.BaseRecognizer.AlreadyParsedRule(Stimulsoft.Data.Expressions.Antlr.Runtime.IIntStream,System.Int32)"]
