Detailed Description

template<typename T, std::size_t N>
class donut::graphics::ShaderArray< T, N >

Fixed-size array of uniform shader variable identifiers representing an array inside a ShaderProgram.

Template Parameters

T	the type of uniform shader variable identifier to use for each element of the array.
N	the number of elements in the array.

Examples

example_game.cpp.

Constructor & Destructor Documentation

ShaderArray()

template<typename T , std::size_t N>

donut::graphics::ShaderArray< T, N >::ShaderArray ( const ShaderProgram &  program, const char *  name  )

inline

Construct an array of uniform shader variable identifiers for a specific shader array.

Parameters

program	shader program in which the array resides.
name	name of the array.

Exceptions

std::bad_alloc

on allocation failure.

Note

If the array elements are not found, the resulting identifiers will be invalid.

Member Function Documentation

size()

template<typename T , std::size_t N>

std::size_t donut::graphics::ShaderArray< T, N >::size ( ) const

inlinenoexcept

Get the size of the array.

Returns

the number of elements in the array, which is always equal to template parameter N.

operator[]() [1/2]

template<typename T , std::size_t N>

T & donut::graphics::ShaderArray< T, N >::operator[] ( std::size_t  i )

inline

Access an element of the array.

Parameters

i	the index of the element to get. Must be less than the size of the array.

Returns

a reference to the element at index i.

operator[]() [2/2]

template<typename T , std::size_t N>

const T & donut::graphics::ShaderArray< T, N >::operator[] ( std::size_t  i ) const

inline

Access an element of the array.

Parameters

i	the index of the element to get. Must be less than the size of the array.

Returns

a read-only reference to the element at index i.

begin()

template<typename T , std::size_t N>

decltype(auto) donut::graphics::ShaderArray< T, N >::begin ( ) const

inlinenoexcept

Get an iterator to the beginning of the array.

Returns

the begin iterator.

end()

template<typename T , std::size_t N>

decltype(auto) donut::graphics::ShaderArray< T, N >::end ( ) const

inlinenoexcept

Get an iterator to the end of the array.

Returns

the end iterator.
