Method Detail

execute

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

Get the given string's pointer object which was passed to TruffleString.FromNativePointerNode. If the string is not backed by a native pointer, this node will throw an UnsupportedOperationException. Use AbstractTruffleString.isNative() to check whether the string is actually backed by a native pointer before calling this node. Caution: If the given string is a TruffleString, the native pointer must not be modified as long as the string is used.
