Method Detail

execute

public abstract boolean execute(AbstractTruffleString a,
                                TruffleString.CodeRange codeRange)

Returns true if the string's code range is equal to the given TruffleString.CodeRange. Use this operation when caching code range instances, e.g.:

 
 @Specialization(guards = "codeRangeEqualsNode.execute(a, cachedCodeRange)")
 static void someOperation(TString a,
                 @Cached TruffleString.GetCodeRangeNode getCodeRangeNode,
                 @Cached TruffleString.CodeRangeEqualsNode codeRangeEqualsNode,
                 @Cached("getCodeRangeNode.execute(this, a)") CodeRange cachedCodeRange) {
     // ...
 }
