Class Collection

object --+    
         |    
      list --+
             |
            Collection

Multiple objects (organized as a list).

Methods are applied to all objects in the Collection and returned as new Collection:

>>> from gromacs.analysis.collections import Collection
>>> animals = Collection(['ant', 'boar', 'ape', 'gnu'])
>>> animals.startswith('a')
Collection([True, False, True, False])

Similarly, attributes are returned as a Collection.

Using :meth:`Collection.save` one can save the whole collection to disk and restore it later with the :meth:`Collection.load` method

>>> animals.save('zoo')
>>> arc = Collection()
>>> arc.load('zoo')
>>> arc.load('zoo', append=True)
>>> arc
['ant', 'boar', 'ape', 'gnu', 'ant', 'boar', 'ape', 'gnu']
