Detailed Description

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

This class provides all public-facing non-const-qualified methods of slices. It only re-implements the const-qualified versions as non-const.

Constructor & Destructor Documentation

◆ MutableSliceBase()

template<template< typename > class storage_type, typename data_type>
Exiv2::Internal::MutableSliceBase< storage_type, data_type >::MutableSliceBase ( data_type &  data,
size_t  begin,
size_t  end 
)
inline

Forwards everything to the constructor of const_slice_base

Todo:
use using once we have C++11

Member Function Documentation

◆ at()

template<template< typename > class storage_type, typename data_type>
value_type& Exiv2::Internal::MutableSliceBase< storage_type, data_type >::at ( size_t  index)
inline

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

Exceptions
std::out_of_rangewhen index is out of bounds of the slice

◆ begin()

template<template< typename > class storage_type, typename data_type>
iterator Exiv2::Internal::MutableSliceBase< storage_type, data_type >::begin ( )
throw (
)
inline

Obtain an iterator to the first element in the slice.

◆ end()

template<template< typename > class storage_type, typename data_type>
iterator Exiv2::Internal::MutableSliceBase< storage_type, data_type >::end ( )
throw (
)
inline

Obtain an iterator to the first element beyond the slice.

◆ subSlice()

template<template< typename > class storage_type, typename data_type>
template<typename slice_type >
slice_type Exiv2::Internal::MutableSliceBase< storage_type, data_type >::subSlice ( size_t  begin,
size_t  end 
)
inlineprotected

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

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

◆ to_const_base()

template<template< typename > class storage_type, typename data_type>
ConstSliceBase<storage_type, const data_type> Exiv2::Internal::MutableSliceBase< storage_type, data_type >::to_const_base ( ) const
throw (
)
inlineprotected

Explicitly convert this instance into a base-class of the appropriate constant version of this slice.

This function is required to properly implement the subSlice() const function for mutable slices. The problem here is, that a slice<T> and a slice<const T> actually don't share the same base class ConstSliceBase<storage_type, T>. Instead slice<T> inherits from ConstSliceBase<storage_type, T> and slice<const T> inherits from ConstSliceBase<storage_type, const T>.

Now, slice<T> can call the subSlice() const method from its base class, but that will return a mutable slice<T>! Instead we use this function to convert the `slice<T> into the parent of the appropriate slice<const T> and call its subSlice() const, which returns the correct type.
