详细描述

An iterator that goes forward in an EndpointContainer skipping the NULLs, that also acts a bit like a pointer/smart pointer (can treat it as a vrpn_Endpoint *)

Because we know at design time that it iterates through pointers, we have pointer-related operator overloads that mean there's no need to double-dereference.

Fulfills the InputIterator concept: http://en.cppreference.com/w/cpp/concept/InputIterator

All end() iterators compare equal to each other and to the default-constructed iterator. They are the only invalid iterators: incrementing an iterator past the end makes it the same as the default-constructed iterator.

That is, for all EndpointIterators it, we enforce the class invariant it.valid() || (it == EndpointIterator()) (and that's actually an XOR)

构造及析构函数说明

EndpointIterator() [1/3]

EndpointIterator ( )

inline

Default constructor, equal to all other default-constructed instances and all end()

函数调用图:

EndpointIterator() [2/3]

EndpointIterator ( container_type & container )

inline

Constructor with container, points to beginning of container.

EndpointIterator() [3/3]

EndpointIterator ( container_type & container, size_type index )

inline

Constructor with container and raw index into container.

成员函数说明

get_pointer()

pointer get_pointer ( ) const

inline

Extract the pointer (NULL if iterator is invalid)

这是这个函数的调用关系图:

operator pointer()

operator pointer ( ) const

inline

Implicit conversion operator to pointer.

函数调用图:

operator++()

type & operator++ ( )

inline

prefix ++ operator, increments (and skips any nulls)

Invariant might be invalid here, since the user might have just deleted something.

valid()

bool valid ( ) const

inline

Does this iterator refer to a valid element?

Class invariant: valid() || (*this == type()) That is, there is only one invalid value.
