Method Details

[hide private]

do_check(self)

source code

Subclasses can implement me to run any checks before the component performs setup.

Messages can be added to the component state's 'messages' list key. Any error messages added will trigger the component going to sad, with flumotion.common.errors.ComponentSetupError being raised before getting to setup stage; do_setup() will not be called.

In the event of a fatal problem that can't be expressed through an error message, this method should raise an exception or return a failure.

It is not necessary to chain up in this function. The return value may be a deferred.

Overrides: component.BaseComponent.do_check: (inherited documentation)

get_pipeline_string(self, properties)

source code

Method that must be implemented by subclasses to produce the gstparse string for the component's pipeline. Subclasses should not chain up; this method raises a NotImplemented error.

Returns: a new pipeline string representation.

Overrides: feedcomponent.ParseLaunchComponent.get_pipeline_string: (inherited documentation)

configure_pipeline(self, pipeline, properties)

source code

Method that can be implemented by subclasses if they wish to interact with the pipeline after it has been created and set on the component.

This could include attaching signals and bus handlers.

Overrides: feedcomponent.ParseLaunchComponent.configure_pipeline: (inherited documentation)
