org.bridj.JNI

Deprecated.

These methods can cause serious issues (segmentation fault, system crashes) if used without care : there are little to no checks performed on the arguments.

@Deprecated
public class JNI
extends Object

Low-level calls to JNI and to BridJ's native library.

Method Detail

getEnv

@Deprecated
public static long getEnv()

Deprecated.

getJVM

@Deprecated
public static long getJVM()

Deprecated.

refToObject

@Deprecated
public static Object refToObject(long refPeer)

Deprecated.

newGlobalRef

public static long newGlobalRef(Object object)

Deprecated.

Create a JNI global reference to a Java object : long value that can be safely passed to C programs and stored, which prevent the object from being garbage-collected and which validity runs until deleteGlobalRef(long) is called

deleteGlobalRef

public static void deleteGlobalRef(long reference)

Deprecated.

Delete a global reference created by newGlobalRef(java.lang.Object)

getGlobalPointer

public static Pointer<?> getGlobalPointer(Object object)

Deprecated.

newWeakGlobalRef

public static long newWeakGlobalRef(Object object)

Deprecated.

Create a JNI weak global reference to a Java object : long value that can be safely passed to C programs and stored, which validity runs until deleteWeakGlobalRef(long) is called.
Unlike global references, weak global references don't prevent objects from being garbage-collected.

deleteWeakGlobalRef

public static void deleteWeakGlobalRef(long reference)

Deprecated.

Delete a weak global reference created by newWeakGlobalRef(java.lang.Object)

newDirectByteBuffer

public static ByteBuffer newDirectByteBuffer(long address,
                             long capacity)

Deprecated.

Wrap a native address as a direct byte buffer of the specified byte capacity.
Memory is not reclaimed when the buffer is garbage-collected.

getDirectBufferAddress

public static long getDirectBufferAddress(Buffer b)

Deprecated.

Get the native address pointed to by a direct buffer.

getDirectBufferCapacity

public static long getDirectBufferCapacity(Buffer b)

Deprecated.

Get the capacity in bytes of a direct buffer.

callSinglePointerArgVoidFunction

public static void callSinglePointerArgVoidFunction(long functionPointer,
                                    long pointerArg,
                                    int callMode)

Deprecated.
