Class IteratorFactory.NeighbourIterator<E>

java.lang.Object
chemaxon.util.iterator.IteratorFactory.NeighbourIterator<E>
All Implemented Interfaces:
Iterator<E>
Direct Known Subclasses:
IteratorFactory.AtomNeighbourIterator, IteratorFactory.BondNeighbourIterator
Enclosing class:
IteratorFactory
public abstract class IteratorFactory.NeighbourIterator<E> extends Object implements Iterator<E>
The NeighbourIterator class provides an iterator to process the bonds connecting to the specified atom according to the atom and bond related behavior of this factory.

  • Field Summary

    Modifier and Type
    Field
    Description
    protected MolAtom
    atom
    The atom whose the neighbours are processed.
    protected int
    currentBond
    Current bond pointer of the iterator.
    protected List<MolBond>
    secondaryBonds
    Secondary bonds that replace a coordinate bond to the multicenter with coordinate bonds from the metal to the represented atoms (in the MulticenterSgroup of the multicenter).

    Method
    Description
    protected MolBond
    getBond(int index)
    Returns a bond of a specified index.
    boolean
    hasNext()
    Decides whether the iteration has more element.
    protected int
    nextBondIndex(int index)
    Returns the next bond index in the iteration according to the atom and bond related behavior specified in the factory.
    void
    remove()
    The remove operation is not supported by this Iterator implementation.

  • Field Details

    • atom

      protected MolAtom atom
      The atom whose the neighbours are processed.

    • currentBond

      protected int currentBond
      Current bond pointer of the iterator.

    • secondaryBonds

      protected List<MolBond> secondaryBonds
      Secondary bonds that replace a coordinate bond to the multicenter with coordinate bonds from the metal to the represented atoms (in the MulticenterSgroup of the multicenter). These secondary bonds are not added to the molecule of the factory, so do not use Molecule.indexOf for the secondary bonds! In the future, secondary bonds may be implemented for other types of connections too.

  • Constructor Details

    • NeighbourIterator

      protected NeighbourIterator(MolAtom atom)
      Constructs an iterator to process the bonds connecting to the specified atom. The following bonds are excluded:
      • bonds excluded in the bond related behavior of the factory and
      • bonds connecting to atoms that are excluded in the atom related behavior of the factory.
      Parameters:
      atom - the atom whose bonds to be iterated

  • Method Details

    • getBond

      protected MolBond getBond(int index)
      Returns a bond of a specified index.
      Parameters:
      index - the specified index of the bond
      Returns:
      the bond of the specified index

    • hasNext

      public boolean hasNext()
      Decides whether the iteration has more element.
      Specified by:
      hasNext in interface Iterator<E>
      Returns:
      true if the iteration has more element, false otherwise.

    • nextBondIndex

      protected int nextBondIndex(int index)
      Returns the next bond index in the iteration according to the atom and bond related behavior specified in the factory.
      Parameters:
      index - the current index to get the subsequent index from
      Returns:
      the subsequent index

    • remove

      public void remove()
      The remove operation is not supported by this Iterator implementation.
      Specified by:
      remove in interface Iterator<E>
      Throws:
      UnsupportedOperationException
