[keywords transfer copy channel {data destination} receiver]
[para]
This package pulls data destinations and connection setup together
into a combined object for the reception of information coming in over
a socket. These objects understand all the options from objects
created by the packages [package transfer::data::destination] and
[package transfer::connect].

[list_begin definitions]
[call [cmd transfer::receiver] \
[arg object] \
[opt [arg options]...]]
This command creates and configures a new receiver
[arg object]. The fully qualified name of the object command is
returned as the result of the command.
[nl]
See the packages [package transfer::data::destination]
and [package transfer::connect] for the main options recognized. Here
we describe only the options which go beyond the referenced set.
[list_begin opt]
[opt_def -command [arg cmdprefix]]
This option specifies the command to invoke when the transmission of
the information in the data source has been completed. The arguments
given to this command are the same as given to the completion callback
of method [cmd receive], see package
[package transfer::data::destination].
[list_end]
[call [arg object] [method destroy]]
This method destroys the object. Doing so while a reception is on
progress will cause errors later on, when the reception completes
and tries to access the now missing data structures of the destroyed
object.
[call [arg object] [method start]]
This method initiates the data reception, setting up the connection
first and then copying the received information into the
destination. The method will throw an error if a reception is
already/still in progress. I.e. it is not possible to run two
receptions in parallel, only in sequence. Errors will also be thrown
if the configuration of the data destination is invalid, or if no
completion callback was specified.
The result returned by the method the same as the result of method
[method connect], see package [package transfer::connect].
[call [arg object] [method busy]]
This method returns a boolean value telling us whether a reception
is in progress ([const True]), or not ([const False]).
