Description

CategoryManagerIter [constructor]

Create an iterator providing non‐modifiable access to the categories in the specified categoryManager that is initialized to refer to the first category in the sequence of categories in the registry of categoryManager, if one exists, and is initialized to be invalid otherwise. The order of iteration is undefined. The behavior is undefined unless the lifetime of categoryManager is at least as long as the lifetime of this iterator.

operator()

Return a const reference to the category currently referred to by this iterator. The behavior is undefined unless this iterator is valid.

operator++

Advance this iterator to refer to the next unvisited category. If no such category exists, this iterator becomes invalid. The behavior is undefined unless this iterator is initially valid. Note that the order of iteration is undefined.

operator void const*

Return a non‐zero value if this iterator is valid, and 0 otherwise.
