Method Details

execute

public abstract boolean execute(AbstractTruffleString a,
 AbstractTruffleString b,
 TruffleString.Encoding expectedEncoding)

Returns true if a and b are byte-by-byte equal when considered in expectedEncoding. Note that this method requires both strings to be compatible to the expectedEncoding, just like all other operations with an expectedEncoding parameter!

The AbstractTruffleString.equals(Object)-method delegates to this method.
