Method Detail

addItem

public boolean addItem(T item)

Description copied from interface: Algorithm

Adds an item to the algorithm

Parameters:

item - the item to be added

Returns:

true if the algorithm contents changed as a result of the call

addItems

public boolean addItems(java.util.Collection<T> items)

Description copied from interface: Algorithm

Adds a collection of items to the algorithm

Parameters:

items - the items to be added

Returns:

true if the algorithm contents changed as a result of the call

clearItems

public void clearItems()

removeItem

public boolean removeItem(T item)

Description copied from interface: Algorithm

Removes an item from the algorithm

Parameters:

item - the item to be removed

Returns:

true if this algorithm contained the specified element (or equivalently, if this algorithm changed as a result of the call).

removeItems

public boolean removeItems(java.util.Collection<T> items)

Description copied from interface: Algorithm

Removes a collection of items from the algorithm

Parameters:

items - the items to be removed

Returns:

true if this algorithm contents changed as a result of the call

updateItem

public boolean updateItem(T item)

Description copied from interface: Algorithm

Updates the provided item in the algorithm

Parameters:

item - the item to be updated

Returns:

true if the item existed in the algorithm and was updated, or false if the item did not exist in the algorithm and the algorithm contents remain unchanged.
