◆ operator>>() [1/2]

template<class K , class Allocator >

std::istream & operator>>	(	std::istream &	in,
		DynamicVector< K, Allocator > &	v
	)

Note: This operator is STL compliant, i.e., the content of v is only changed if the read operation is successful.

Parameters

[in]	in	std :: istream to read from
[out]	v	DynamicVector to be read

Returns: the input stream (in)

◆ operator>>() [2/2]

template<class K , int SIZE>

std::istream & operator>>	(	std::istream &	in,
		FieldVector< K, SIZE > &	v
	)

Note: This operator is STL compliant, i.e., the content of v is only changed if the read operation is successful.

Parameters

[in]	in	std :: istream to read from
[out]	v	FieldVector to be read

Returns: the input stream (in)

Random-access operator.

This method mimics the behavior of normal vector access with square brackets like, e.g., m[5] = .... The problem is that the return type is different for each value of the argument in the brackets. Therefore we implement a trick using std::integral_constant. To access the first row of a MultiTypeBlockMatrix named m write

std::integral_constant<size_type,0> _0;

m[_0] = ...

Dune::Indices::_0

constexpr index_constant< 0 > _0

Compile time index with value 0.

Definition: indices.hh:52

The name '_0' used here as a static replacement of the integer number zero is arbitrary. Any other variable name can be used. If you don't like the separate variable, you can write

m[std::integral_constant<size_type,0>()] = ...

◆ operator[]() [2/2]

template<typename FirstRow , typename... Args>

template<size_type index>

auto Dune::MultiTypeBlockMatrix< FirstRow, Args >::operator[] ( const std::integral_constant< size_type, index > indexVariable ) const -> decltype(std::get<index>(*this))

inline

Const random-access operator.

This is the const version of the random-access operator. See the non-const version for a full explanation of how to use it.
