| Buffer() | 
| Modifier and Type | Method and Description | 
|---|---|
| static long | address(ByteBuffer buf)Returns the memory address of the ByteBuffer. | 
| static ByteBuffer | calloc(int num,
      int size)Allocate a new ByteBuffer from memory and set all of the memory to 0 | 
| static ByteBuffer | create(long mem,
      int size)Allocate a new ByteBuffer from already allocated memory. | 
| static void | free(ByteBuffer buf)Deallocates or frees a memory block used by ByteBuffer
  Warning : Call this method only on ByteBuffers that were created by calling Buffer.alloc or Buffer.calloc. | 
| static ByteBuffer | malloc(int size)Allocate a new ByteBuffer from memory | 
| static ByteBuffer | palloc(long p,
      int size)Allocate a new ByteBuffer from a pool | 
| static ByteBuffer | pcalloc(long p,
       int size)Allocate a new ByteBuffer from a pool and set all of the memory to 0 | 
| static long | size(ByteBuffer buf)Returns the allocated memory size of the ByteBuffer. |
