Detailed Description

Base class for all Mox comparators.

A Comparator can be used as a parameter to a mocked method when the exact
value is not known.  For example, the code you are testing might build up a
long SQL string that is passed to your mock DAO. You're only interested that
the IN clause contains the proper primary keys, so you can set your mock
up as follows:

mock_dao.RunQuery(StrContains('IN (1, 2, 4, 5)')).AndReturn(mock_result)

Now whatever query is passed in must contain the string 'IN (1, 2, 4, 5)'.

A Comparator may replace one or more parameters, for example:
# return at most 10 rows
mock_dao.RunQuery(StrContains('SELECT'), 10)

or

# Return some non-deterministic number of rows
mock_dao.RunQuery(StrContains('SELECT'), IsA(int))
