Detailed Description

Specifies a single triangular prism in a tetrahedron.

If a tetrahedron contains normal quads, slicing along these quads splits the tetrahedron into two triangular prisms (and possibly some additional product regions). Each triangular prism contains two of the vertices and one of the edges of the original tetrahedron.

These objects are small enough to pass by value and swap with std::swap(), with no need for any specialised move operations or swap functions.

Precondition

This class should only be used with embedded normal surfaces.

Constructor & Destructor Documentation

PrismSpec() [1/3]

regina::PrismSpec::PrismSpec ( )

default

Creates a new uninitialised prism specifier.

PrismSpec() [2/3]

regina::PrismSpec::PrismSpec ( size_t newTetIndex, int newEdge )

inline

Creates a new prism specifier containing the given values.

Parameters

newTetIndex	the index in the triangulation of the tetrahedron containing the prism.
newEdge	the edge of the tetrahedron that is contained in this prism; this must be between 0 and 5 inclusive.

PrismSpec() [3/3]

regina::PrismSpec::PrismSpec ( const PrismSpec & cloneMe )

default

Creates a new prism specifier that is a clone of the given specifier.

Parameters

cloneMe

the prism specifier to clone.

Member Function Documentation

operator!=()

bool regina::PrismSpec::operator!= ( const PrismSpec & other ) const

inline

Determines if this and the given prism specifier contain different information.

Parameters

other

the prism specifier to compare with this.

Returns

true if and only if this and the given prism specifier contain different information.

operator=()

PrismSpec & regina::PrismSpec::operator= ( const PrismSpec & cloneMe )

default

Copies the values from the given prism specifier into this specifier.

Parameters

cloneMe

the prism specifier whose values should be copied.

Returns

a reference to this prism specifier.

operator==()

bool regina::PrismSpec::operator== ( const PrismSpec & other ) const

inline

Determines if this and the given prism specifier contain identical information.

Parameters

other

the prism specifier to compare with this.

Returns

true if and only if this and the given prism specifier contain identical information.

Friends And Related Symbol Documentation

operator<<

std::ostream & operator<< ( std::ostream & out, const PrismSpec & spec )

friend

Writes the given prism specifier to the given output stream.

The prism specifier will be written as a pair (tetIndex, edge).

Parameters

out	the output stream to which to write.
spec	the prism specifier to write.

Returns

a reference to out.

Member Data Documentation

edge

int regina::PrismSpec::edge

The edge of the tetrahedron that is contained in this prism.

tetIndex

size_t regina::PrismSpec::tetIndex

The index in the triangulation of the tetrahedron containing the prism.
