Method Detail- 
getDatabasepublic FbWireDatabase getDatabase() - Specified by:
- getDatabasein interface- FbBlob
- Overrides:
- getDatabasein class- AbstractFbBlob
- Returns:
- The database connection that created this blob
 
 - 
getHandlepublic final int getHandle() 
 - 
setHandleprotected final void setHandle(int blobHandle) - Parameters:
- blobHandle- The Firebird blob handle identifier
 
 - 
releaseBlobprotected void releaseBlob(int releaseOperation) throws java.sql.SQLExceptionRelease this blob with the specified operation.Implementations should only do the operation and not perform any further clean up or checks on attached database and active transaction, as those checks and clean up should be done by the caller. - Parameters:
- releaseOperation- Either- WireProtocolConstants.op_close_blobor- WireProtocolConstants.op_cancel_blob
- Throws:
- java.sql.SQLException- For database communication errors.
 
 - 
closeImplprotected void closeImpl() throws java.sql.SQLExceptionDescription copied from class:AbstractFbBlobInternal implementation ofAbstractFbBlob.close(). The implementation does not need to check for attached database and active transaction, nor does it need to mark this blob as closed.- Specified by:
- closeImplin class- AbstractFbBlob
- Throws:
- java.sql.SQLException
 
 - 
cancelImplprotected void cancelImpl() throws java.sql.SQLExceptionDescription copied from class:AbstractFbBlobInternal implementation ofAbstractFbBlob.cancel(). The implementation does not need to check for attached database and active transaction, nor does it need to mark this blob as closed.- Specified by:
- cancelImplin class- AbstractFbBlob
- Throws:
- java.sql.SQLException
 
 - 
releaseResourcesprotected void releaseResources() Description copied from class:AbstractFbBlobRelease Java resources held. This should not communicate with the Firebird server.- Specified by:
- releaseResourcesin class- AbstractFbBlob
 
 - 
getBlobInfopublic byte[] getBlobInfo(byte[] requestItems, int bufferLength) throws java.sql.SQLExceptionDescription copied from interface:FbBlobRequest blob info.- Specified by:
- getBlobInfoin interface- FbBlob
- Parameters:
- requestItems- Array of info items to request
- bufferLength- Response buffer length to use
- Returns:
- Response buffer
- Throws:
- java.sql.SQLException
