Constructor Detail

CatalogItemImpl

public CatalogItemImpl(String sName)
Create a new CatalogItemImpl. The item's value defaults to an IntegerValue of 0.

Parameters:
sName - the name of the new item.

CatalogItemImpl

public CatalogItemImpl(String sName,
                       Value vValue)
Create a new CatalogItemImpl.

Parameters:
sName - the name of the new item.
vValue - the value of the item.
Method Detail

getValue

public Value getValue()
Get the item's value.

Specified by:
getValue in interface CatalogItem
Returns:
a clone of the item's value.
Override:
Never

setValue

protected void setValue(Value vNew)
Set the item's value. This method is protected so that subclasses can decide whether or not to allow clients to set the value of a CatalogItem once it has been created.

The method will fire a property change event for the "value" property.

Override:
Sometimes

isEditable

public boolean isEditable()
Return true if this CatalogItem is editable.

Override:
Never

getCatalog

public Catalog getCatalog()
Get the Catalog of this CatalogItem.

Specified by:
getCatalog in interface CatalogItem
Override:
Never

toString

public String toString()
Return a String representation of the item.

Override:
Sometimes

getShallowClone

protected abstract CatalogItemImpl getShallowClone()
Get a shallow clone of the CatalogItem. For normal CatalogItems there is no difference between a shallow and a deep clone.

Override:
Always

compareTo

public int compareTo(Object o)
Compare this CatalogItem to an object.

Specified by:
compareTo in interface Comparable
Throws:
ClassCastException - if the given object cannot be cast into a CatalogItem.
Override:
Sometimes The default implementation assumes that the given object is also a CatalogItem and compares the names of these two CatalogItems.

equals

public boolean equals(Object o)
Check whether two objects are equal.

Override:
Sometimes The default implementation returns true iff o is identical to this object.

addValueListener

public void addValueListener(PropertyChangeListener pcl)
Add a PropertyChangeListener that will receive events whenever the "value" property changes.

Specified by:
addValueListener in interface CatalogItem
Override:
Never

removeValueListener

public void removeValueListener(PropertyChangeListener pcl)
Remove a PropertyChangeListener for the "value" property.

Specified by:
removeValueListener in interface CatalogItem
Override:
Never
