RWTPtrMapIterator provides a const
iterator interface to the C++ Standard Library-based RWTPtrMap collection. As a const
iterator, it prohibits any change to the collection upon which it iterates.
The order of iteration over an RWTPtrMap is dependent on the comparator object supplied as applied to the key values of the stored associations.
The current item referenced by this iterator is undefined after construction or after a call to reset(). The iterator becomes valid after being advanced with either a preincrement or operator()().
For both operator++() and operator()(), iterating past the last element returns a value equivalent to boolean false
. Continued increments return a value equivalent to false
until reset() is called.
The value
type must have operator==
and operator<
defined. This requirement is imposed by the C++ Standard Library.
None
|
inline |
Creates a const
iterator for the map rwm. The iterator begins in an undefined state and must be advanced before the first element is accessible.
|
inline |
Creates a const
iterator from the iterator itr. The const
iterator begins in an undefined state and must be advanced before the first element is accessible.
|
inline |
Returns a pointer to the collection being iterated over.
|
inline |
Returns the key portion of the association currently referenced by self. Undefined if self is not referencing a value within the map.
|
inline |
Advances self to the next element, dereferences the resulting iterator, and returns its key. If the iterator has advanced past the last item in the container, rwnil will be returned.
|
inline |
Advances self to the next element. If the iterator has been reset or just created self now references the first element. If, before iteration, self referenced the last association in the multimap, self now points to an undefined value, and a value equivalent to false
is returned. Otherwise, a value equivalent to true
is returned.

inline |
Resets the iterator so that after being advanced, it will reference the first element of the collection.
|
inline |
Resets the iterator so that after being advanced, it will reference the first element of the collection m.
|
inline |
Returns the value portion of the association pointed to by self. Undefined if self is not referencing a value within the map.
