OEIsMemberPtr¶
template<class C>
class OEIsMemberPtr : public OESystem::OEUnaryPredicate<C>
This class represents OEIsMemberPtr
template functor that
performs set membership tests. This functor differs
from the OEIsMember
functor in that the internal
storage type differs from the test type.
While instances of abstract classes cannot be easily
stored, however, pointers to abstract class instances do not pose
the same storage problems.
OEIsMemberPtr
stores pointers to
data types, while the template type of the class is a single
dereferenced version of the storage type.

Constructors¶
OEIsMemberPtr()
Default constructor.
OEIsMemberPtr(OESystem::OEIter<C> &i)
Constructs the functor using an iterator (OEIter
)
over values of the same type as the functor template argument.
Addresses instead of instances or references to the data are
stored internally.
OEIsMemberPtr(OESystem::OEIterBase<C> *i)
Constructs the functor using an iterator (OEIterBase
)
over values of the same type as the functor template argument.
Addresses instead of instances or references to the data are
stored internally.
template<class T> OEIsMemberPtr(T bgn, T end)
Constructs the functor using a sequence of values. The values from ‘bgn’ up to, but not including ‘end’ are used to construct the functor. Using this constructor, the functor may be constructed from arrays and STL containers.
operator=¶
OEIsMemberPtr<C> &operator=(const OEIsMemberPtr<C> &rhs)
Assignment operator that copies the data of the ‘rhs’ OEIsMemberPtr
object
into the right-hand side OEIsMemberPtr
object.
operator()¶
bool operator()(const C &arg) const
Returns true
if a pointer to the object ‘arg’ is contained in the
functor.
CreateCopy¶
OESystem::OEUnaryPredicate<C> *CreateCopy() const
Deep copy constructor that returns a copy of the object.
The memory for the returned OEIsMemberPtr
object is dynamically allocated and owned by the caller.
Set¶
template<class T>
bool Set(T bgn, T end)
