How to get all the selected objects of a given class
====================================================

In this example we will show how to get all the selected objects of the class *Channel*.

First, perform the import statements::

    from OrsLibraries.workingcontext import WorkingContext
    from ORSModel import Channel
    from ORSModel import OrsSelectedObjects

Then, request the selected objects of the class *Channel*, kept in the entity named with the tag *OrsSelectedObjects*::

    allSelectedDatasets = WorkingContext.getEntitiesOfClass(aPluginInstance, OrsSelectedObjects, Channel.getClassNameStatic())

where *aPluginInstance* is a plugin instance. This plugin instance is used to determine from what context this
information should be taken from (since there is a dictionary of entities per context); the information is taken
from the context in which this plugin instance belongs.
However, in the situation where there is only one context or the request is made for the current context,
*None* can be used instead of *aPluginInstance*::

    allSelectedDatasets = WorkingContext.getEntitiesOfClass(None, OrsSelectedObjects, Channel.getClassNameStatic())

*allSelectedDatasets* is a Python list of the selected objects (as contained in the dictionary of entities
kept by *WorkingContext*).
