Detailed Description

Class: Expr::iterator Author: Sergey Berezin Created: Fri Dec 6 15:38:51 2002 Description: STL-like iterator API to the Expr's children. IMPORTANT: the iterator will not be valid after the originating expression is destroyed.

Member Function Documentation

bool CVCL::Expr::iterator::operator== (  const iterator &  i  )  const [inline]

Equality. Definition at line 225 of file expr.h. References d_it.

bool CVCL::Expr::iterator::operator!= (  const iterator &  i  )  const [inline]

Disequality. Definition at line 229 of file expr.h.

const Expr & CVCL::Expr::iterator::operator * (   )  const

Dereference operator. Definition at line 438 of file expr.cpp. References d_it. Referenced by operator->().

const Expr * CVCL::Expr::iterator::operator-> (   )  const

Dereference and member access. Definition at line 442 of file expr.cpp. References operator *().

iterator& CVCL::Expr::iterator::operator++ (   )  [inline]

Prefix increment. Definition at line 235 of file expr.h. References d_it.

Proxy CVCL::Expr::iterator::operator++ (  int   )  [inline]

Postfix increment. Returns: Proxy with the old Expr. Now, an expression like *i++ will return the current *i, and then advance the iterator. However, don't try to use Proxy for anything else. Definition at line 254 of file expr.h.
