com.sun.cldc.jna
Class Native

java.lang.Object
  com.sun.cldc.jna.Native

public class Native
extends Object
extends Object

Generic machinery to support access to native code.

Differences from JNA

Throws RuntimeExceptions instead of UnsatisfiedLinkErrors. Are link errors really "unrecoverable"? Platform independant code might want to work around missing functions.
Search paths unimplemented
Calling conventions unimplemented
no finalization in cldc, need to call dispose() explicitly (could add a shutdownhook though).
no parseVersion();
no getFile()

Field Summary
`static boolean`	`DEBUG`

`static int`	`LONG_SIZE`
`static int`	`POINTER_SIZE`
`static int`	`WCHAR_SIZE`

Method Summary
`static boolean[]`	`doInitCheck(boolean[] checkArray, int length, int index)` a bit of sanity checking that every "constant index" is really unique and every one is checked.
`static NativeLibrary`	`getLibraryLoading()` Kludge to pass loading library to default constructor of implementation class.
`static Library`	`loadLibrary(String name, Class interfaceClass)`

Method Detail

getLibraryLoading

public static NativeLibrary getLibraryLoading()

Kludge to pass loading library to default constructor of implementation class.

Returns:: NativeLibrary or null if not loading a NativeLibrary.

loadLibrary

public static Library loadLibrary(String name,
                                  Class interfaceClass)

doInitCheck

public static boolean[] doInitCheck(boolean[] checkArray,
                                    int length,
                                    int index)

a bit of sanity checking that every "constant index" is really unique and every one is checked. once this is autogenerated this will be less necessary

Parameters:: checkArray - the current value of the check array (may be null); length - the length of the check array; index - the index being checked.
Returns:: the checkArray object
