Netchannels.trans_out_obj_channel
A transactional output channel has a buffer for uncommitted data. * This means that all data written to this channel is collected in the * buffer until either commit_work
or rollback_work
is called. * * When the channel is closed, the buffer may optionally be committed. * This is implementation-defined. * * The method flush
does not have any effect on the transaction * buffer.
inherit out_obj_channel
Flushes the transaction buffer, and writes its contents to the * underlying resource.
