Representation of a task in a TaskGraph. Each Task has, at creation:
|
|
|
|
- kind: the name of the task kind
|
|
- label; the label for this task
|
|
- attributes: a dictionary of attributes for this task (used for filtering)
|
|
- task: the task definition (JSON-able dictionary)
|
|
- optimizations: optimizations to apply to the task (see taskgraph.optimize)
|
|
- dependencies: tasks this one depends on, in the form {name: label}, for example
|
|
{'build': 'build-linux64/opt', 'docker-image': 'build-docker-image-desktop-test'}
|
|
|
|
And later, as the task-graph processing proceeds:
|
|
|
|
- task_id -- TaskCluster taskId under which this task will be created
|
|
- optimized -- true if this task need not be performed
|
|
|
|
This class is just a convenience wraper for the data type and managing
|
|
display, comparison, serialization, etc. It has no functionality of its own.
