All Implemented Interfaces:

NodeInterface, Cloneable

Enclosing class:

TruffleString

Method Details

execute

public final boolean execute(AbstractTruffleString a,
 int fromByteIndexA,
 AbstractTruffleString b,
 int fromByteIndexB,
 int length,
 TruffleString.Encoding expectedEncoding)

Checks for a region match, byte-by-byte.

Since:

22.1

execute

public final boolean execute(AbstractTruffleString a,
 int fromByteIndexA,
 TruffleString.WithMask b,
 int fromByteIndexB,
 int length,
 TruffleString.Encoding expectedEncoding)

Checks for a region match, byte-by-byte. This variant accepts a TruffleString.WithMask as the search value b, which changes the matching algorithm in the following manner: when 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);
 }
