BaseRecognizerGetRuleMemoization Method

Given a rule number and a start token index number, return MEMO_RULE_UNKNOWN if the rule has not parsed input starting from start index. If this rule has parsed input starting from the start index before, then return where the rule stopped parsing. It returns the index of the last token matched by the rule.

Copy
public virtual int GetRuleMemoization(
	int ruleIndex,
	int ruleStartIndex
)

Parameters

ruleIndex
Type: SystemInt32

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

ruleStartIndex
Type: SystemInt32

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

Return Value

Type: Int32

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

Remarks
For now we use a hashtable and just the slow Object-based one. Later, we can make a special one for ints and also one that tosses out data after we commit past input position i.
