Method Detail

getFilterType

public Class<E> getFilterType()

Returns:

the filterType

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<E>

next

public E next()

Specified by:

next in interface Iterator<E>

remove

public void remove()

Removes the current element from the underlying collection. This method may only be called immediately after a call to next(). If you call hasNext() after next() but before remove(), we must throw an IllegalStateException because the underlying Iterator has already iterated further.

Specified by:

remove in interface Iterator<E>

Throws:

UnsupportedOperationException - if the underlying collection's iterator does not support remove

IllegalStateException - if you have called a method of this iterator after the last successful next() operation
