Detailed Description

Iterator to traverse and mutate a linear expression.

As const_iterator, but for non-constant linexpr1.

Caution: do not modify the expression during traversal, except through the iterator.

Sample code:

for (linexpr1::iterator i = m.begin();i.valid();++i) i.get_coeff().neg(); 

Constructor & Destructor Documentation

iterator() [1/3]

apron::linexpr1::iterator::iterator ( ap_linexpr1_t * l )

inlineprotected

Internal use only.

iterator() [2/3]

linexpr1::iterator::iterator ( linexpr1 & e )

inline

Starts a new iterator to traverse the linear expression.

iterator() [3/3]

linexpr1::iterator::iterator ( const iterator & i )

inline

Duplicates the iterator.

Member Function Documentation

get_coeff()

coeff & linexpr1::iterator::get_coeff ( ) const

inline

Returns a (modifiable) reference to the coefficient at the current iterator position.

Exceptions

std::out_of_range

if valid() returns false (we are past the last position).

operator=()

linexpr1::iterator & linexpr1::iterator::operator= ( const iterator & i )

inline

Assigns the iterator.
