inline

operator+() [1/2]

WALBERLA_HOST_DEVICE Cell walberla::cell::Cell::operator+ ( ) const

inline

Unary plus operator.

Returns

*this unmodified.

operator+() [2/2]

WALBERLA_HOST_DEVICE Cell walberla::cell::Cell::operator+ ( const Cell & rhs ) const

inline

Operator for component-wise addition of two cells.

Parameters

[in]

rhs

The cell added to this.

Returns

a Cell which components are the sum of this and rhs components

operator+=()

WALBERLA_HOST_DEVICE Cell & walberla::cell::Cell::operator+= ( const Cell & rhs )

inline

Additive compound assignment operator.

Parameters

[in]

rhs

The cell added to this.

Returns

Reference to this.

operator-() [1/2]

WALBERLA_HOST_DEVICE Cell walberla::cell::Cell::operator- ( ) const

inline

Unary negation operator.

Returns

Cell with negated components.

operator-() [2/2]

WALBERLA_HOST_DEVICE Cell walberla::cell::Cell::operator- ( const Cell & rhs ) const

inline

Operator for component-wise subtraction of two cells.

Parameters

[in]

rhs

The cell subtracted from this.

Returns

a Cell which components are the difference of this and rhs components

operator-=()

operator<()

WALBERLA_HOST_DEVICE bool walberla::cell::Cell::operator< ( const Cell & rhs ) const

inline

Less-than comparison operator for Cells.

Compares a cell's coordinates lexicographically (first z, then y, then x).

Parameters

[in]

rhs

the cell compared to *this.

Returns

true if this cell is lexicographically smaller than rhs when comparing coordinates in the order z, then y, then x.

operator==()

WALBERLA_HOST_DEVICE bool walberla::cell::Cell::operator== ( const Cell & rhs ) const

inline

Equal comparison operator for Cells.

Compares a cell's coordinates for equality (first x, then eventually y and (if necessary) finally z).

Parameters

[in]

rhs

The cell compared to *this.

Returns

(this->x == rhs.x) && (this->y == rhs.y) && (this->z == rhs.z) 

operator[]() [1/2]

WALBERLA_HOST_DEVICE cell_idx_t & walberla::cell::Cell::operator[] ( std::size_t idx )

inline

Operator providing element access of a Cell.

Parameters

[in]

idx

Zero-based index of the cell's coordinate component.

Returns

The idx-th coordinate component. This is equal to this->cell[i].

operator[]() [2/2]

WALBERLA_HOST_DEVICE cell_idx_t walberla::cell::Cell::operator[] ( std::size_t idx ) const

inline

Operator providing read-only element access of a const Cell.

Parameters

[in]

idx

Zero-based index of the cell's coordinate component.

Returns

The idx-th coordinate component. This is equal to this->cell[i].
