Method Detail

containsInternal

protected boolean containsInternal(Object o)

Specified by:

containsInternal in class AbstractContext<T>

iteratorInternal

protected Iterator<T> iteratorInternal()

Specified by:

iteratorInternal in class AbstractContext<T>

sizeInternal

protected int sizeInternal()

Specified by:

sizeInternal in class AbstractContext<T>

addInternal

protected boolean addInternal(T o)

Specified by:

addInternal in class AbstractContext<T>

removeInternal

protected boolean removeInternal(Object obj)

Specified by:

removeInternal in class AbstractContext<T>

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<T>

Overrides:

removeAll in class AbstractCollection<T>

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<T>

Overrides:

retainAll in class AbstractCollection<T>

getObjects

public IndexedIterable<T> getObjects(Class<?> clazz)

Gets a IndexedIterable over the all the objects in this context (and thus in the sub contexts) that are of the specified type.

Parameters:

clazz - the type of objects to return

Returns:

a IndexedIterable over the all the objects in this context (and thus in the sub contexts) that are of the specified type.

getRandomObjects

public Iterable<T> getRandomObjects(Class<? extends T> clazz,
                                    long count)

Gets an iterable over a collection of objects chosen at random. The number of objects is determined by the specified count and the type of objects by the specified class. If the context contains less objects than the specified count, all the appropriate objects in the context will be returned.

If this is repeatedly called with a count equal to the number of objects in the context, the iteration order will be shuffled each time.

Parameters:

clazz - the class of the objects to return

count - the number of random objects to return

Returns:

an iterable over a collection of random objects

getRandomObject

public T getRandomObject()

Gets an object in this context chosen at random from a uniform distribution.

Returns:

an object in this context chosen at random from a uniform distribution.
