Constructor Detail

SubRequestIteratorSupport

public SubRequestIteratorSupport(Iterator<?> subRequests)

Creates a SubRequestIterator that decorates an Iterator.

Parameters:

subRequests - an Iterator on SubRequest instances or instances of other objects if mapToSubRequest(Object element) is implemented (overwritten) accordingly.

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: SubRequestIterator

Returns true if there are more sub-requests to process. In other words, returns true if next would return an element rather than throwing an exception.

Specified by:

hasNext in interface Iterator<S extends SubRequest<?>>

Specified by:

hasNext in interface SubRequestIterator<S extends SubRequest<?>>

Returns:

true if there are more sub-requests.

next

public S next()

Description copied from interface: SubRequestIterator

Gets the next sub-request that is pending.

Specified by:

next in interface Iterator<S extends SubRequest<?>>

Specified by:

next in interface SubRequestIterator<S extends SubRequest<?>>

Returns:

an unprocessed SubRequest instance.

remove

public void remove()

Specified by:

remove in interface Iterator<S extends SubRequest<?>>

mapToSubRequest

protected S mapToSubRequest(Object element)

Returns the SubRequest contained or represented by the supplied object (element of the iterator). The default implementation simply casts the supplied object to SubRequest.

Parameters:

element - an Object from which a SubRequest can be deduced.

Returns:

a SubRequest instance.
