| Method Summary | |
| public int | available(int _index)
Returns the available bytes of this BLOB beginning at index. | | public void | init(int _pageSize)
| | public void | onDelete()
| | protected int | pageNum(int index)
| | protected int | pageOff(int index)
| | public byte[] | read(int index, int len)
| | public void | write(int _index, byte[] b, int off, int len)
Writes the content of the Array into the BLOB starting at index. |
| DEFAULT_PAGE_SIZE | | final protected static int DEFAULT_PAGE_SIZE(Code) | | |
| debug | | protected boolean debug(Code) | | |
| pageSize | | protected int pageSize(Code) | | |
| BLOBContainerImpl | | public BLOBContainerImpl()(Code) | | |
| available | | public int available(int _index) throws Exception(Code) | | Returns the available bytes of this BLOB beginning at index.
NEVER WRITE ON BLOB WHILE EXECUTING THIS METHOD!
Parameters:
_index - the startposition the number of available bytes after _index
exception:
Exception - (some kind of databaseexception ?) |
| init | | public void init(int _pageSize)(Code) | | |
| onDelete | | public void onDelete() throws Exception(Code) | | THIS MUST BE CALLED ON DELETE TO KILL ALL REFERENCED BLOBPAGES !
(hope the database does this for me...)
|
| pageNum | | protected int pageNum(int index)(Code) | | |
| pageOff | | protected int pageOff(int index)(Code) | | |
| write | | public void write(int _index, byte[] b, int off, int len) throws Exception(Code) | | Writes the content of the Array into the BLOB starting at index.
Parameters:
_index - the write startposition in the BLOB
Parameters:
b - the bytearray to be stored
Parameters:
off - the startindex in the bytearray
Parameters:
len - the number of bytes to be written into the BLOB
exception:
Exception - |
