Member Function Documentation

flat()

template<int dim>

std::int64_t qugar::TensorIndexRangeTP< dim >::Iterator::flat ( ) const

nodiscard

Transforms the current tensor index into a flat one by considering the upper bound as associated size.

Returns

Computed flat index.

operator!=()

template<int dim>

bool qugar::TensorIndexRangeTP< dim >::Iterator::operator!= ( const Iterator & rhs ) const

nodiscard

Compares if two iterators are different. They are considered to be different if at least one of the components of their indices or bounds are different.

Parameters

rhs	Iterator to compare to the current one.

Returns

Whether both iterators are different.

operator*()

template<int dim>

const TensorIndexTP< dim > & qugar::TensorIndexRangeTP< dim >::Iterator::operator* ( ) const

nodiscard

Dereference operator.

Returns

Reference to the index pointed by the iterator.

operator++() [1/2]

template<int dim>

Iterator & qugar::TensorIndexRangeTP< dim >::Iterator::operator++

(

)

Pre increments the iterator.

Returns

Updated iterator.

operator++() [2/2]

template<int dim>

Iterator qugar::TensorIndexRangeTP< dim >::Iterator::operator++

(

int

)

Post increments the iterator.

Returns

Updated iterator.

operator->()

template<int dim>

const TensorIndexTP< dim > * qugar::TensorIndexRangeTP< dim >::Iterator::operator-> ( ) const

nodiscard

Indirection operator.

Returns

Pointer to the index pointed by the iterator.

operator==()

template<int dim>

bool qugar::TensorIndexRangeTP< dim >::Iterator::operator== ( const Iterator & rhs ) const

nodiscard

Compares if two iterators are equal. They are considered to be equal if their indices and bounds are equal for all the components.

Parameters

rhs	Iterator to compare to the current one.

Returns

Whether both iterators are equal.
