| Inner Class :public enum Type | |
| Method Summary | |
| abstract public void | clear()
Releases any referenced memory. | | final public ByteBuffer | getBuffer(PageChannel pageChannel, int size)
Returns a ByteBuffer of at least the given size, with the limit set to
the given size, and the predefined byteOrder. | | abstract public ByteBuffer | getExistingBuffer()
| | public int | getModCount()
| | final public ByteBuffer | getPageBuffer(PageChannel pageChannel)
Returns a ByteBuffer of at least the defined page size, with the limit
set to the page size, and the predefined byteOrder. | | public static TempBufferHolder | newHolder(Type type, boolean autoRewind)
Creates a new TempBufferHolder. | | public static TempBufferHolder | newHolder(Type type, boolean autoRewind, ByteOrder order)
Creates a new TempBufferHolder. | | abstract protected void | setNewBuffer(ByteBuffer newBuffer)
Sets a new buffer for this holder. |
| TempBufferHolder | | protected TempBufferHolder(boolean autoRewind, ByteOrder order)(Code) | | |
| clear | | abstract public void clear()(Code) | | Releases any referenced memory.
|
| getBuffer | | final public ByteBuffer getBuffer(PageChannel pageChannel, int size)(Code) | | Returns a ByteBuffer of at least the given size, with the limit set to
the given size, and the predefined byteOrder. Will be rewound iff
autoRewind is enabled for this buffer.
|
| getExistingBuffer | | abstract public ByteBuffer getExistingBuffer()(Code) | | null |
| getModCount | | public int getModCount()(Code) | | the modification count of the current buffer (this count ischanged every time the buffer is reallocated) |
| getPageBuffer | | final public ByteBuffer getPageBuffer(PageChannel pageChannel)(Code) | | Returns a ByteBuffer of at least the defined page size, with the limit
set to the page size, and the predefined byteOrder. Will be rewound iff
autoRewind is enabled for this buffer.
|
| newHolder | | public static TempBufferHolder newHolder(Type type, boolean autoRewind)(Code) | | Creates a new TempBufferHolder.
Parameters:
type - the type of reference desired for any created buffer
Parameters:
autoRewind - whether or not every get automatically rewinds thebuffer |
| newHolder | | public static TempBufferHolder newHolder(Type type, boolean autoRewind, ByteOrder order)(Code) | | Creates a new TempBufferHolder.
Parameters:
type - the type of reference desired for any created buffer
Parameters:
autoRewind - whether or not every get automatically rewinds thebuffer
Parameters:
order - byte order for all allocated buffers |
| setNewBuffer | | abstract protected void setNewBuffer(ByteBuffer newBuffer)(Code) | | Sets a new buffer for this holder.
