Detailed Description

template<template< typename data_type > class storage_type, typename data_type>
struct Exiv2::Internal::ConstSliceBase< storage_type, data_type >

This class provides the public-facing const-qualified methods of a slice.

The public methods are implemented in a generic fashion using a storage_type. This type contains the actual reference to the data to which the slice points and provides the following methods:

• (const) value_type& unsafeAt(size_t index) (const) Return the value at the given index of the underlying container, without promising to perform a range check and without any knowledge of the slices' size
• const_iterator/iterator unsafeGetIteratorAt(size_t index) (const) Return a (constant) iterator at the given index of the underlying container. Again, no range checks are promised.
• Constructor(data_type& data, size_t begin, size_t end) Can use begin & end to perform range checks on data, but should not store both values. Must not take ownership of data!
• Must save data as a public member named data_.
• Must provide appropriate typedefs for iterator, const_iterator and value_type

Constructor & Destructor Documentation

ConstSliceBase()

template<template< typename data_type > class storage_type, typename data_type >

Exiv2::Internal::ConstSliceBase< storage_type, data_type >::ConstSliceBase ( data_type &  data, size_t  begin, size_t  end  )

inline

Default constructor, requires begin to be smaller than end, otherwise an exception is thrown. Also forwards all parameters to the constructor of storage_

Member Function Documentation

at()

template<template< typename data_type > class storage_type, typename data_type >

const value_type& Exiv2::Internal::ConstSliceBase< storage_type, data_type >::at ( size_t  index ) const

inline

Obtain a constant reference to the element with the specified index in the slice.

Exceptions

std::out_of_range

when index is out of bounds of the slice

cbegin()

template<template< typename data_type > class storage_type, typename data_type >

const_iterator Exiv2::Internal::ConstSliceBase< storage_type, data_type >::cbegin ( ) const

inlinenoexcept

Obtain a constant iterator to the first element in the slice.

References Exiv2::Internal::SliceBase::begin_, and Exiv2::Internal::ConstSliceBase< storage_type, data_type >::storage_.

cend()

template<template< typename data_type > class storage_type, typename data_type >

const_iterator Exiv2::Internal::ConstSliceBase< storage_type, data_type >::cend ( ) const

inlinenoexcept

Obtain a constant iterator to the first beyond the slice.

References Exiv2::Internal::ConstSliceBase< storage_type, data_type >::storage_.

subSlice()

template<template< typename data_type > class storage_type, typename data_type >

template<typename slice_type >

slice_type Exiv2::Internal::ConstSliceBase< storage_type, data_type >::subSlice ( size_t  begin, size_t  end  ) const

inline

Create a constant sub-slice with the given bounds (with respect to the current slice).

Template Parameters

slice_type

Type of the slice that this function shall return. Provide it with the type of the class that derives from mutable_slice_base.
