Method Detail

execute

public final int execute(AbstractTruffleString a,
                         AbstractTruffleString b,
                         int fromByteIndex,
                         int toByteIndex,
                         TruffleString.Encoding expectedEncoding)

TruffleString.IndexOfStringNode, but with byte indices.

Since:

22.1

execute

public final int execute(AbstractTruffleString a,
                         TruffleString.WithMask b,
                         int fromByteIndex,
                         int toByteIndex,
                         TruffleString.Encoding expectedEncoding)

TruffleString.IndexOfStringNode, but with byte indices. This variant accepts a TruffleString.WithMask as the search value b, which changes the searching algorithm in the following manner: whenever the contents of a and b are compared, the mask is OR'ed to a, as shown in this exemplary method:

 
 boolean bytesEqualAt(TruffleString a, int byteIndexA, TruffleString.WithMask b, int byteIndexB) {
     return (readByte(a, byteIndexA) | readByte(b.mask, byteIndexB)) == readByte(b, byteIndexB);
 }
