Abstract base class for the subtask of `DefineVisitsTask` that is responsible for grouping exposures into visits. Subclasses should be registered with `GroupExposuresTask.registry` to enable use by `DefineVisitsTask`, and should generally correspond to a particular 'visit_system' dimension value. They are also responsible for defining visit IDs and names that are unique across all visit systems in use by an instrument. Parameters ---------- config : `GroupExposuresConfig` Configuration information. **kwargs Additional keyword arguments forwarded to the `Task` constructor.

Get schema catalogs for all tasks in the hierarchy, combining the results into a single dict. Returns ------- schemacatalogs : `dict` Keys are butler dataset type, values are a empty catalog (an instance of the appropriate `lsst.afw.table` Catalog type) for all tasks in the hierarchy, from the top-level task down through all subtasks. Notes ----- This method may be called on any task in the hierarchy; it will return the same answer, regardless. The default implementation should always suffice. If your subtask uses schemas the override `Task.getSchemaCatalogs`, not this method.

Get metadata for all tasks. Returns ------- metadata : `lsst.daf.base.PropertySet` The `~lsst.daf.base.PropertySet` keys are the full task name. Values are metadata for the top-level task and all subtasks, sub-subtasks, etc. Notes ----- The returned metadata includes timing information (if ``@timer.timeMethod`` is used) and any metadata set by the task. The name of each item consists of the full task name with ``.`` replaced by ``:``, followed by ``.`` and the name of the item, e.g.:: topLevelTaskName:subtaskName:subsubtaskName.itemName using ``:`` in the full task name disambiguates the rare situation that a task has a subtask and a metadata item with the same name.

Get the task name as a hierarchical name including parent task names. Returns ------- fullName : `str` The full name consists of the name of the parent task and each subtask separated by periods. For example: - The full name of top-level task "top" is simply "top". - The full name of subtask "sub" of top-level task "top" is "top.sub". - The full name of subtask "sub2" of subtask "sub" of top-level task "top" is "top.sub.sub2".

Get the name of the task. Returns ------- taskName : `str` Name of the task. See also -------- getFullName

Get the schemas generated by this task. Returns ------- schemaCatalogs : `dict` Keys are butler dataset type, values are an empty catalog (an instance of the appropriate `lsst.afw.table` Catalog type) for this task. Notes ----- .. warning:: Subclasses that use schemas must override this method. The default implementation returns an empty dict. This method may be called at any time after the Task is constructed, which means that all task schemas should be computed at construction time, *not* when data is actually processed. This reflects the philosophy that the schema should not depend on the data. Returning catalogs rather than just schemas allows us to save e.g. slots for SourceCatalog as well.

Get a dictionary of all tasks as a shallow copy. Returns ------- taskDict : `dict` Dictionary containing full task name: task object for the top-level task and all subtasks, sub-subtasks, etc.

Tuple[int, str] lsst.obs.base.defineVisits.GroupExposuresTask.getVisitSystem | ( | self | ) |
Return identifiers for the 'visit_system' dimension this algorithm implements. Returns ------- id : `int` Integer ID for the visit system (given an instrument). name : `str` Unique string identifier for the visit system (given an instrument).
Reimplemented in lsst.obs.base.defineVisits._GroupExposuresByGroupMetadataTask, and lsst.obs.base.defineVisits._GroupExposuresOneToOneTask.

Iterable[VisitDefinitionData] lsst.obs.base.defineVisits.GroupExposuresTask.group | ( | self, | |
List[DimensionRecord] | exposures | ||
) |
Group the given exposures into visits. Parameters ---------- exposures : `list` [ `DimensionRecord` ] DimensionRecords (for the 'exposure' dimension) describing the exposures to group. Returns ------- visits : `Iterable` [ `VisitDefinitionData` ] Structs identifying the visits and the exposures associated with them. This may be an iterator or a container.
Reimplemented in lsst.obs.base.defineVisits._GroupExposuresByGroupMetadataTask, and lsst.obs.base.defineVisits._GroupExposuresOneToOneTask.

Make a `lsst.pex.config.ConfigurableField` for this task. Parameters ---------- doc : `str` Help text for the field. Returns ------- configurableField : `lsst.pex.config.ConfigurableField` A `~ConfigurableField` for this task. Examples -------- Provides a convenient way to specify this task is a subtask of another task. Here is an example of use: .. code-block:: python class OtherTaskConfig(lsst.pex.config.Config): aSubtask = ATaskClass.makeField("brief description of task")

Create a subtask as a new instance as the ``name`` attribute of this task. Parameters ---------- name : `str` Brief name of the subtask. keyArgs Extra keyword arguments used to construct the task. The following arguments are automatically provided and cannot be overridden: - "config". - "parentTask". Notes ----- The subtask must be defined by ``Task.config.name``, an instance of `~lsst.pex.config.ConfigurableField` or `~lsst.pex.config.RegistryField`.

Context manager to log performance data for an arbitrary block of code. Parameters ---------- name : `str` Name of code being timed; data will be logged using item name: ``Start`` and ``End``. logLevel A `lsst.log` level constant. Examples -------- Creating a timer context: .. code-block:: python with self.timer("someCodeToTime"): pass # code to time See also -------- timer.logInfo
