Method Detail

addStrategies

public TraversalStrategies addStrategies(TraversalStrategy<?>... strategies)

Description copied from interface: TraversalStrategies

Add all the provided TraversalStrategy instances to the current collection. When all the provided strategies have been added, the collection is resorted. If a strategy class is found to already be defined, it is removed and replaced by the newly added one.

Specified by:

addStrategies in interface TraversalStrategies

Parameters:

strategies - the traversal strategies to add

Returns:

the newly updated/sorted traversal strategies collection

removeStrategies

public TraversalStrategies removeStrategies(Class<? extends TraversalStrategy>... strategyClasses)

Description copied from interface: TraversalStrategies

Remove all the provided TraversalStrategy classes from the current collection. When all the provided strategies have been removed, the collection is resorted.

Specified by:

removeStrategies in interface TraversalStrategies

Parameters:

strategyClasses - the traversal strategies to remove by their class

Returns:

the newly updated/sorted traversal strategies collection

toList

public List<TraversalStrategy<?>> toList()

Description copied from interface: TraversalStrategies

Return an immutable list of the TraversalStrategy instances.

Specified by:

toList in interface TraversalStrategies

iterator

public Iterator<TraversalStrategy<?>> iterator()

Description copied from interface: TraversalStrategies

Return an Iterator of the TraversalStrategy instances.

Specified by:

iterator in interface Iterable<TraversalStrategy<?>>

Specified by:

iterator in interface TraversalStrategies

getStrategy

public <T extends TraversalStrategy> Optional<T> getStrategy(Class<T> traversalStrategyClass)

Description copied from interface: TraversalStrategies

Return the TraversalStrategy instance associated with the provided class.

Specified by:

getStrategy in interface TraversalStrategies

Type Parameters:

T - the strategy class type

Parameters:

traversalStrategyClass - the class of the strategy to get

Returns:

an optional containing the strategy instance or not

clone

public DefaultTraversalStrategies clone()

Specified by:

clone in interface TraversalStrategies

Overrides:

clone in class Object

toString

public String toString()

Overrides:

toString in class Object
