Method Details

execute

public abstract void execute(AbstractTruffleString a,
 int byteFromIndexA,
 Object pointerObject,
 int byteFromIndexDst,
 int byteLength,
 TruffleString.Encoding expectedEncoding)

Copy a region of the given TruffleString a, bounded by byteFromIndexA and byteLength into the given interop object representing a native pointer (isPointer(pointerObject) must return true), starting at byteFromIndexDst.

This operation requires native access permissions (TruffleLanguage.Env#isNativeAccessAllowed()).
