The CDesiredTypes predicate is a ring item
type selector that skips all ring item types except those in its
item/flag list. The flag determines if the data for that item type are
sampled (if true) or if all items of that type are
accepted (if false).
addDesiredType is used to build up the list
of desired item types.
CDesiredTypesPredicate();
Constructs the predicate with an empty list of desired types.
If no types are added via addDesiredType,
the predicate will skip all of the data in the ring
(not very useful).
CDesiredTypesPredicate(unsigned int nType, uint32_t* types);
Constructs the predicate with nType types
in its acceptance list. These types are specified in the
array types. The sample flags on all of these
types is set to false
so that all items of these types are accepted.
CDesiredTypesPredicate(unsigned int nType, uint32_t* types, bool* sample);
Same as the previous constructor, however the sample flags for
each item type are explicitly specified by the
sample
array.
CDesiredTypesPredicate(const CDesiredTypesPredicate& rhs);
Provides support for creating a new predicate by copying a previously existing one.
CDesiredTypesPredicate& operator=(const CDesiredTypesPredicate& rhs);
Provides support for replacing the acceptance list of an existing
object with the acceptance list of rhs.
const int operator==(const CDesiredTypesPredicate& rhs);
Provides a mechanism for comparing two predicates for equality.
const int operator!=(const CDesiredTypesPredicate& rhs);
Provides the mechanism for comparing two predicates for inequality.
void addDesiredType(uint32_t type, bool sample = false);
Adds a type to the set of item types that may be accepteed by the
predicate. type is the type id, and
sample the flag that determines if the types
are accepted in sampled mode.
