Hi, Jim,
No, there is no API spec available at the moment -- you have to read
the source for now. We are working on a tool to produce Javadoc-style
web pages for the X10 library classes, but no ETA on that yet.
I believe the method you're looking for is
public final def read[T](m: Marshal[T], a: Rail[T], off: Int, len:
Int): Void throws IOException;
inherited from x10.io.Reader, which you'd use it as follows:
val file: FileReader = ...;
file.read(Marshal.BYTE, letterBytes, 0, letterBytes.length());
You can also use the read[T](Marshal[T], Rail[T]) helper method,
like this:
val file: FileReader = ...;
file.read(Marshal.BYTE, letterBytes);
Hope this helps,
Igor
