      SQLite.Blob

public class Blob
extends Object

Class to represent SQLite3 3.4.0 incremental blob I/O interface. Note, that all native methods of this class are not synchronized, i.e. it is up to the caller to ensure that only one thread is in these methods at any one time.

Field Summary
`private long` | `handle` Internal handle for the SQLite3 blob.
`protected int` | `size` Cached size of blob, setup right after blob has been opened.

Constructor Summary
`Blob()`

Method Summary
`void` | `close()` Close blob.
`protected void` | `finalize()` Destructor for object.
`InputStream` | `getInputStream()` Return InputStream for this blob
`OutputStream` | `getOutputStream()` Return OutputStream for this blob
`private static void` | `internal_init()` Internal native initializer.
`(package private) int` | `read(byte[] b, int off, int pos, int len)` Internal blob read method.
`(package private) int` | `write(byte[] b, int off, int pos, int len)` Internal blob write method.
