Constructor Detail

ChemObject

public ChemObject()

Constructs a new IChemObject.

ChemObject

public ChemObject(IChemObject chemObject)

Constructs a new IChemObject by copying the flags, and the identifier. It does not copy the listeners and properties.

Parameters:

chemObject - the object to copy

Method Detail

addListener

public void addListener(IChemObjectListener col)

Use this to add yourself to this IChemObject as a listener. In order to do so, you must implement the ChemObjectListener Interface.

Specified by:

addListener in interface IChemObject

Parameters:

col - the ChemObjectListener

See Also:

removeListener(org.openscience.cdk.interfaces.IChemObjectListener)

getListenerCount

public int getListenerCount()

Returns the number of ChemObjectListeners registered with this object.

Specified by:

getListenerCount in interface IChemObject

Returns:

the number of registered listeners.

removeListener

public void removeListener(IChemObjectListener col)

Use this to remove a ChemObjectListener from the ListenerList of this IChemObject. It will then not be notified of change in this object anymore.

Specified by:

removeListener in interface IChemObject

Parameters:

col - The ChemObjectListener to be removed

See Also:

addListener(org.openscience.cdk.interfaces.IChemObjectListener)

notifyChanged

public void notifyChanged()

This should be triggered by an method that changes the content of an object to that the registered listeners can react to it.

Specified by:

notifyChanged in interface IChemObject

notifyChanged

public void notifyChanged(IChemObjectChangeEvent evt)

This should be triggered by an method that changes the content of an object to that the registered listeners can react to it. This is a version of notifyChanged() which allows to propagate a change event while preserving the original origin.

Specified by:

notifyChanged in interface IChemObject

Parameters:

evt - A ChemObjectChangeEvent pointing to the source of where the change happened

setProperty

public void setProperty(Object description,
                        Object property)

Sets a property for a IChemObject.

Specified by:

setProperty in interface IChemObject

Parameters:

description - An object description of the property (most likely a unique string)

property - An object with the property itself

See Also:

getProperty(java.lang.Object), removeProperty(java.lang.Object)

removeProperty

public void removeProperty(Object description)

Removes a property for a IChemObject.

Specified by:

removeProperty in interface IChemObject

Parameters:

description - The object description of the property (most likely a unique string)

See Also:

setProperty(java.lang.Object, java.lang.Object), getProperty(java.lang.Object)

getProperty

public <T> T getProperty(Object description)

Returns a property for the IChemObject.

Specified by:

getProperty in interface IChemObject

Parameters:

description - An object description of the property (most likely a unique string)

Returns:

The object containing the property. Returns null if propert is not set.

See Also:

setProperty(java.lang.Object, java.lang.Object), removeProperty(java.lang.Object)

getProperty

public <T> T getProperty(Object description,
                         Class<T> c)

Specified by:

getProperty in interface IChemObject

getProperties

public Map<Object,Object> getProperties()

Returns a Map with the IChemObject's properties.

Specified by:

getProperties in interface IChemObject

Returns:

The object's properties as an Hashtable

See Also:

addProperties(java.util.Map<java.lang.Object, java.lang.Object>)

clone

public Object clone()
             throws CloneNotSupportedException

Clones this IChemObject. It clones the identifier, flags, properties and pointer vectors. The ChemObjectListeners are not cloned, and neither is the content of the pointer vectors.

Specified by:

clone in interface IChemObject

Overrides:

clone in class Object

Returns:

The cloned object

Throws:

CloneNotSupportedException

compare

Specified by:

setID in interface IChemObject

Parameters:

identifier - a String representing the ID value

                    boolean value)

Specified by:
