Class Native

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

public class Native
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()

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
