Filtering

Operations requiring selection of entities based on attribute values may
provide a filter construct.

This filter construct may be based on primitive.filter or be associated
via common operations stereotypes (see common operations).

A common operation stereotype may define a filter as being a template
or a combination of a template and a query filter.

A query filter is mapped to a string which is implementation technology specific. For example in XML it is filled by the implementation with an XPATH expression. In java it is filled by a JPA query expression.

A template filter is mapped to a sequence of attribute matching filters
(using associative lookup).

When both template and query filters are specified then a choice construct
is being generated.

Operation using primitive filters as input arguments are mapped to operations
using query filters.
