Constructor & Destructor Documentation

QNumSpace()

uni20::QNumSpace::QNumSpace ( QNum  qnum, std::string  label = {}  )

inlineexplicit

Parameters

qnum	Irrep label and its required symmetry context.
label	Semantic leg label.

Member Function Documentation

label()

auto uni20::QNumSpace::label ( ) const -> std::string const&

inline

Return the semantic leg label.

Returns

Label, which may be empty.

operator==()

auto uni20::QNumSpace::operator== ( QNumSpace const &  other ) const -> bool=default

default

Compare irrep and label.

Parameters

other

Other QNum space.

Returns

true when structure and label are equal.

qnum()

auto uni20::QNumSpace::qnum ( ) const -> QNum const&

inline

Return the irrep label.

Returns

Stored quantum number.

set_label()

void uni20::QNumSpace::set_label ( std::string  label )

inline

Replace the semantic leg label without changing the irrep.

Parameters

label

New label.

symmetry()

auto uni20::QNumSpace::symmetry ( ) const -> Symmetry

inline

Return the symmetry of the irrep label.

Returns

QNum-space symmetry.
