Detailed Description

Iterate over all bonds in an OBMol.

To facilitate iteration through all bonds in a molecule, without resorting to bond indexes (which may change in the future), a variety of iterators are provided.

This has been made significantly easier by a series of macros in the obiter.h header file:

      \#define FOR_BONDS_OF_MOL(b,m)     for( OBMolBondIter     b(m); b; ++b )

Here is an example:

      #include <openbabel/obiter.h>
      #include <openbabel/mol.h>

      OBMol mol;
      unsigned int bondOrderSum = 0;
      FOR_BONDS_OF_MOL(b, mol)
      {
         // The variable b behaves like OBBond* when used with -> and * but
         // but needs to be explicitly converted when appearing as a parameter
         // in a function call - use &*b
         bondOrderSum +=  b->GetBO();
      }

Member Function Documentation

OBMolBondIter & operator= ( const OBMolBondIter bi  ) 

operator bool (  )  const [inline]

Returns:
Whether the iterator can still advance (i.e., visit more bonds)

OBMolBondIter & operator++ (  ) 

Preincrement -- advance to the next bond and return.

OBMolBondIter operator++ ( int   ) 

Postincrement -- return the current bond and advance to the next.

OBBond* operator-> (  )  const [inline]

Returns:
a pointer to the current bond

OBBond& operator * (  )  const [inline]

Returns:
a reference to the current bond
