Detailed Description

template<int RANK, bool IS_CONST>
class DimensionsBookkeeper< RANK, IS_CONST >

Stores and manipulates dimensions of constructs over composite Hilbert spaces of arbitrary arity.

It can be either constant or non-constant depending on the second template parameter.

Template Parameters
RANKarity of the Hilbert space
IS_CONSTGoverns the constness

Constructor & Destructor Documentation

template<int RANK, bool IS_CONST>
DimensionsBookkeeper< RANK, IS_CONST >::DimensionsBookkeeper ( mpl::bool_< IS_CONST >  = mpl::false_())
inlineexplicit

Constructor usable only in the IS_CONST=false case.

The aim of the dummy argument with a default value – which creates a nonsensical function signature for IS_CONST=true – is that this constructor only compile for IS_CONST=false because it is only in the non-constant case that we allow default construction of the class.

Since from a template only such parts are compiled as are actually used, a client can use the class in the case IS_CONST=true without problems, getting a compile-time error only when trying to default-construct such an object.
