Method Detail

addItem

boolean addItem(T item)

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

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

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

void clearItems()

removeItem

boolean removeItem(T item)

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).

updateItem

boolean updateItem(T item)

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.

removeItems

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

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

getClusters

java.util.Set<? extends Cluster<T>> getClusters(float zoom)

getItems

java.util.Collection<T> getItems()

setMaxDistanceBetweenClusteredItems

void setMaxDistanceBetweenClusteredItems(int maxDistance)

getMaxDistanceBetweenClusteredItems

int getMaxDistanceBetweenClusteredItems()

lock

void lock()

unlock
