Method Details

execute

public abstract long execute(AbstractTruffleString a,
 int fromByteIndex,
 int toByteIndex,
 TruffleString.StringSet stringSet)

Returns the byte index of the first occurrence of any string present in the given TruffleString.StringSet, bounded by fromByteIndex (inclusive) and toByteIndex (exclusive). The returned long packs the resulting byte index into the high 32 bits and the matching pattern's index into the low 32 bits. If no match is found, the result packs -1 for both fields. If multiple strings match at the first matching byte index, the string with the lowest index in the array passed to TruffleString.StringSet.fromArray(AbstractTruffleString[], Encoding) is selected.

TruffleString.ByteIndexOfStringSetNode will specialize on the given TruffleString.StringSet's content, which is therefore required to be partial evaluation constant.

unpackResultByteIndex

public static int unpackResultByteIndex(long result)

Returns the byte index part of a result returned by execute(AbstractTruffleString, int, int, TruffleString.StringSet).

Since:

unpackResultPatternIndex

public static int unpackResultPatternIndex(long result)

Returns the pattern index part of a result returned by execute(AbstractTruffleString, int, int, TruffleString.StringSet).

public static boolean resultIsMatch(long result)

Returns true if the given result, as returned by execute(AbstractTruffleString, int, int, TruffleString.StringSet), represents a successful match.
