Method Details

execute

public abstract int execute(AbstractTruffleString a,
 int i)

Decode and return the codepoint at codepoint index i. This node is a specialized version of TruffleString.CodePointAtIndexNode for UTF-32 strings, with best-effort error handling. This node should be preferred over the generic TruffleString.CodePointAtIndexNode when possible for better performance during warmup / in interpreter mode.
