DESCRIPTION

Provides a class to invoke asynchronous services. Its use is very similar to MOBY::Client::Service, but it also provides additional methods in order to have more control over the asynchronous service execution.

METHODS

new

Name       :    new
Function   :    create a service connection.
Usage      :    $Service = MOBY::Client::Service->new(@args)
Args       :    service - string with a WSDL defining an asynchronous
                          MOBY service
Returns    :    MOBY::Async::Service object, undef if no wsdl.

silent

Name       :    silent
Function   :    get/set silent mode; if silent is not set, status messages
                reported when execute method is invoked.
Usage      :    $Service->silent()
                $Service->silent($boolean)
Args       :    $boolean - 0 or 1 (default).
Returns    :    0 or 1.

execute

 Name       :    execute
 Function   :    execute the asynchronous MOBY service; this method invoke
                 internally to the submit, poll and result methods. It
		 calculates polling time according to the status messages
		 received from the provider. If from that messages is not
		 possible to infer the polling time, it calculates a
		 pseudo-random polling time, whoose value increases until
		 is up to around 1 hour.
 Usage      :    $result = $Service->execute(%args)
 Args       :    XMLinputlist => \@data
 Returns    :    a MOBY message containing whatever the service provides
                 as output.
 Comment    :    for more information about arguments look up execute
                 method at MOBY::Client::Service.

enumerated_execute

Name       :    enumerated_execute
Function   :    execute the asynchronous MOBY service using self-enumerated
                inputs; this method invoke internally to the enumerated_submit,
                poll and result methods. It calculates polling time according
                to the status messages received from the provider. If from
                that messages is not possible to infer the polling time, it
                calculates a pseudo-random polling time, whoose value increases
                until is up to around 1 hour.
Usage      :    $result = $Service->execute(%args)
Args       :    Input => \%data
Returns    :    a MOBY message containing whatever the service provides
                as output.
Comment    :    for more information about arguments look up enumerated_execute
                method at MOBY::Client::Service.

submit

Name       :    submit
Function   :    submit the asynchronous MOBY service.
Usage      :    ($EPR, @queryIDs) = $Service->submit(%args)
Args       :    XMLinputlist => \@data
Returns    :    WSRF::WS_Address object with an EPR and the input queryIDs.
Comment    :    for more information about arguments look up execute
                method at MOBY::Client::Service.

enumerated_submit

Name       :    enumerated_submit
Function   :    submit the asynchronous MOBY service using self-enumerated
                inputs.
Usage      :    ($EPR, @queryIDs) = $Service->submit(%args)
Args       :    XMLinputlist => \%data
Returns    :    WSRF::WS_Address object with an EPR and the input queryIDs.
Comment    :    for more information about arguments look up enumerated_execute
                method at MOBY::Client::Service.

poll

Name       :    poll
Function   :    gets the status of a set of queryIDs.
Usage      :    @status = $Service->poll($EPR, @queryIDs)
Args       :    $EPR      - WSRF::WS_Address object.
                @queryIDs - an array containing queryIDs values.
Returns    :    an array of LSAE::AnalysisEventBlock objects.

result

Name       :    result
Function   :    get the result of a set of queryIDs.
Usage      :    @result = $Service->result($EPR, @queryIDs)
Args       :    $EPR      - WSRF::WS_Address object.
                @queryIDs - an array containing queryIDs values.
Returns    :    an array of MOBY messages.

destroy

Name       :    destroy
Function   :    destroy the resource associated to the execution of
                an asynchronous MOBY service.
Usage      :    $Service->result($EPR);
Args       :    $EPR - WSRF::WS_Address object.
Returns    :    nothing.
