Definition at line 775 of file SbeMessage.h.

iterator_category

template<class EntryType, class BlockLength, class NumInGroup, class Length>

typedef std::input_iterator_tag iterator_category

Definition at line 771 of file SbeMessage.h.

reference

template<class EntryType, class BlockLength, class NumInGroup, class Length>

Constructor & Destructor Documentation

Iterator() [1/2]

template<class EntryType, class BlockLength, class NumInGroup, class Length>

Iterator ( )

defaultnoexcept

Initializes a singular iterator that compares equal to another singular iterator.

Iterator() [2/2]

template<class EntryType, class BlockLength, class NumInGroup, class Length>

Iterator ( typename Entries::Iterator iterator )

inlineexplicitnoexcept

Wraps an existing repeating group iterator.

Parameters

iterator

Position in the borrowed message storage.

Definition at line 786 of file SbeMessage.h.

Member Function Documentation

operator!=()

template<class EntryType, class BlockLength, class NumInGroup, class Length>

bool operator!= ( const Iterator & other ) const

inlinenoexcept

Compares positions within the same repeating group.

Parameters

other

Iterator to compare, or another singular iterator if this is singular.

Returns

Whether the positions differ.

Definition at line 833 of file SbeMessage.h.

operator*()

template<class EntryType, class BlockLength, class NumInGroup, class Length>

EntryType operator* ( ) const

inline

Reads an entry view without transferring ownership of its bytes.

Returns

A view of the current entry.

Definition at line 793 of file SbeMessage.h.

operator++() [1/2]

template<class EntryType, class BlockLength, class NumInGroup, class Length>

Iterator & operator++ ( )

inline

Advances to the next entry.

Returns

This iterator after advancing.

Definition at line 807 of file SbeMessage.h.

operator++() [2/2]

template<class EntryType, class BlockLength, class NumInGroup, class Length>

Iterator operator++ ( int )

inline

Advances while retaining the previous position.

Returns

An independent iterator at the previous entry.

Definition at line 815 of file SbeMessage.h.

operator->()

template<class EntryType, class BlockLength, class NumInGroup, class Length>

pointer operator-> ( ) const

inline

Provides pointer-like access to the current entry view.

Returns

A proxy holding an entry view and borrowing its message bytes.

Definition at line 800 of file SbeMessage.h.

operator==()

template<class EntryType, class BlockLength, class NumInGroup, class Length>

bool operator== ( const Iterator & other ) const

inlinenoexcept

Compares positions within the same repeating group.

Parameters

other

Iterator to compare, or another singular iterator if this is singular.

Returns

Whether the positions are equal.

Definition at line 825 of file SbeMessage.h.
