boolean	isClosed() Check if the batcher has been closed or not.
void	setBatchSize(int batchSize) Sets the batch size.

Method Detail

getBatchSize

int getBatchSize()

Get the current batch size of the batcher. The batch size indicates how many individual items a batcher is caching in memory before they are automatically flushed to the database.

Returns:

The current batch size, or 0 if automatic flushing is turned of

setBatchSize

void setBatchSize(int batchSize)

Sets the batch size. The batch size indicates how many individual items a batcher is caching in memory before they are automatically flushed to the database.

Parameters:

batchSize - Size of the batch, or 0 to disable automatic flushing

isClosed

boolean isClosed()

Check if the batcher has been closed or not. A closed batcher will not accept any more data for insert, update or delete. Note! A batcher that uses an underlying DbControl to connect to the database will automatically be closed when the DbControl is closed.

Returns:

TRUE if the batcher is closed, FALSE otherwise
