Constructor Detail

StockItemImpl

public StockItemImpl(String sName)

Create a new StockItemImpl.

Parameters:

sName - the name of the new item.

Method Detail

getStock

public Stock getStock()

Get the Stock that contains this StockItem.

Specified by:

getStock in interface StockItem

Override:

Never

getAssociatedItem

public CatalogItem getAssociatedItem(DataBasket db)

Get the CatalogItem that is associated with this StockItem.

If the StockItem has a Stock, the associated CatalogItem is the CatalogItem of the same name that is found in the Stock's associated Catalog. Otherwise, it is null.

Specified by:

getAssociatedItem in interface StockItem

Parameters:

db - the DataBasket used to determine visibility.

Override:

Never

setStock

protected void setStock(StockImpl sti)

Set the Stock that contains this StockItem.

Override:

Never

clone

public Object clone()

Clone this StockItem.

Specified by:

clone in interface StockItem

Override:

Always

getShallowClone

public StockItemImpl getShallowClone()

Get a shallow clone of this item.

For a normal item, shallow and deep clones are identical, which is why the default implementation returns ((StockItemImpl) clone()). However, when making a shallow clone of a Stock, the individual StockItems will not be cloned.

Override:

Sometimes The default implementation returns (StockItemImpl) clone().

equals

public boolean equals(Object o)

Check whether this StockItem equals the given object.

Override:

Sometimes The default implementation returns (this == o).

compareTo

public int compareTo(Object o)

Compare this StockItem to the given object.

Specified by:

compareTo in interface Comparable

Throws:

ClassCastException - if the given object cannot be converted into a StockItem.

Override:

Sometimes The default implementation will assume o to be a StockItem and will compare the names. Stocks, however, will always be greater than StockItems.

toString

public String toString()

Return a String representation of the item.

Override:

Sometimes
