Method Detail

resetCache

public static void resetCache()

enableMemoizationOfMatchesForAllRules

public static void enableMemoizationOfMatchesForAllRules(Grammar grammar)

Allows to enable memoization for all rules in given grammar.

Usage of GrammarFunctions.Advanced.memoizeMatches(Object) is preferable than this method, because provides fine-grained control over memoization. Also note that this method was introduced in order to simplify migration from version 1.13 and may disappear in future versions.

1.14
