Class AtomContainer

java.lang.Object
org.openscience.cdk.silent.ChemObject
org.openscience.cdk.silent.AtomContainer
All Implemented Interfaces:
Serializable, Cloneable, IAtomContainer, ICDKObject, IChemObject, IChemObjectListener
Direct Known Subclasses:
Crystal, Monomer, Polymer, Ring, Strand

public class AtomContainer extends ChemObject implements IAtomContainer, IChemObjectListener, Serializable, Cloneable
Base class for all chemical objects that maintain a list of Atoms and ElectronContainers.

Looping over all Bonds in the AtomContainer is typically done like:

 Iterator iter = atomContainer.bonds();
 while (iter.hasNext()) {
   IBond aBond = (IBond) iter.next();
 }

    • removeAtom

      public void removeAtom(IAtom atom)
      Safely remove an atom from the container.
      Removes a single atom from the container updating all internal state to be consistent. All bonds connected to the atom will be deleted as well as all stereo elements. If multiple atoms/bonds are being deleted they should be gathered into a single transaction and removed with IAtomContainer.remove(IAtomContainer).
      If you are removing hydrogens one of the utility methods (e.g. AtomContainerManipulator.removeHydrogens(IAtomContainer)) is preferable.
      Specified by:
      removeAtom in interface IAtomContainer
      Parameters:
      atom - the atom to be removed
    • removeAtom
