extended_environment
method input_ch_async : Uq_engines.async_in_channel
input_ch
channel taken as asynchonous channel. This type of
channel indicates when data is available to read, and also sends notifications.
Note that this is only an alternate interface of the input_ch
object.
The method can_input
returns true when there is at least one byte of
the body to read, or the EOF has been seen. The channel buffers any arriving
data (which can be limited in amount by config_pipeline_size
).
The behaviour of this channel is influenced by the configuration option
config_input_flow_control
.
method output_ch_async : Uq_engines.async_out_channel
output_ch
channel taken as asynchronous channel. This type of
channel indicates when space is available for further output, and also sends
notifications.
Note that this is only an alternate interface of the output_ch
object.
The method can_output
returns true
only when the internal buffer is empty,
i.e. all data have been transmitted to the client. Independent of this, the
channel buffers all data written to it.
The behaviour of this channel is influenced by the configuration option
config_output_flow_control
.
