Method Detail

getArray	back to summary
pack-priv static Object getArray(Object buf) Helper routine to return the array backing store reference from a Buffer object.

getDirectBufferByteOffset	back to summary
pack-priv static int getDirectBufferByteOffset(Object buf) Helper routine to get the Buffer byte offset by taking into account the Buffer position and the underlying type. This is the total offset for Direct Buffers.

getIndirectBufferByteOffset	back to summary
pack-priv static int getIndirectBufferByteOffset(Object buf) Helper routine to get the full byte offset from the beginning of the array that is the storage for the indirect Buffer object. The array offset also includes the position offset within the buffer, in addition to any array offset.

isDirect	back to summary
pack-priv static boolean isDirect(Object buf) Helper routine to tell whether a buffer is direct or not. Null pointers are considered direct. isDirect() should really be in Buffer and not replicated in all subclasses.

isLittleEndian	back to summary
pack-priv static boolean isLittleEndian()

nativeOrder	back to summary
pack-priv static ByteBuffer nativeOrder(ByteBuffer buf) Helper routine to set a ByteBuffer to the native byte order, if that operation is supported by the underlying NIO implementation.

newDirectByteBuffer	back to summary
pack-priv static ByteBuffer newDirectByteBuffer(int size) Helper routine to create a direct ByteBuffer with native order
