Detailed Description

An interface for const iterators on the expression (homogeneous) coefficients that are nonzero.

These iterators are invalidated by operations that modify the expression.

Member Function Documentation

template<typename Row >

Linear_Expression_Interface::const_iterator_interface * Parma_Polyhedra_Library::Linear_Expression_Impl< Row >::const_iterator::clone ( ) const

virtual

Returns a copy of *this. This returns a pointer to dynamic-allocated memory. The caller has the duty to free the memory when it's not needed anymore.

template<typename Row >

void Parma_Polyhedra_Library::Linear_Expression_Impl< Row >::const_iterator::operator++ ( )

virtual

Navigates to the next nonzero coefficient. Note that this method does *not* return a reference, to increase efficiency since it's virtual.

template<typename Row >

void Parma_Polyhedra_Library::Linear_Expression_Impl< Row >::const_iterator::operator-- ( )

virtual

Navigates to the previous nonzero coefficient. Note that this method does *not* return a reference, to increase efficiency since it's virtual.

template<typename Row >

Variable Parma_Polyhedra_Library::Linear_Expression_Impl< Row >::const_iterator::variable ( ) const

virtual

Returns the variable of the coefficient pointed to by *this.

template<typename Row >

bool Parma_Polyhedra_Library::Linear_Expression_Impl< Row >::const_iterator::operator== ( const const_iterator_interface & x ) const

virtual

Compares *this with x .

Parameters

x	The iterator that will be compared with *this.
