Description:
The query component facilitates the process of search and retrieval of model
elements of interest in a flexible yet controlled and structured manner.
Provides API support for the basic EObject based Condition objects that are
used to formulate queries for EMF models.
* The IEObjectSource interface provides the search scope elements to be used
   in a query.
 * The SELECT class implements a template-function that does the iteration over
   model elements and applies the search condition on each; it collects the
   resulting elements into a QueryResultSet object and returns it to the caller
 * The FROM class represents the elements to search. It is responsible of
   providing an appropriate iterator for the elements in the search space.
 * The WHERE class applies the search conditions over the elements in the
   search set.
 * The UPDATE class passes the elements who satisfy the search condition to a
   caller-supplied modification function. It collects the modified elements
   into a QueryResultSet object and returns it to the caller.
 * The QueryResultSet class represents the set of elements returned by a given
   query.
 * The EObjectCondition class is the abstract parent of all conditions that
   deal with model-elements (i.e., EObjects). It incorporates the services of a
   PruneHandler in order to answers whether or not to prune the element tree at
   a specific element and thus ignore its children.
 * The ConditionPolicy class is used to allow the user to decide how to apply a
   given condition on a collection of a model-element EAttributes or
   EReferences values. Supports both the: exists (ANY) and for-all (ALL)
   semantics.
 * The EObjectStructuralFeatureValueCondition class is the parent class for
   conditions that are responsible for checking the values held in model-
   elements attributes or references.
