Constructor Detail

FilteringIterator

public FilteringIterator(java.util.Iterator<? extends Dom> delegate,
                         Condition<? super Dom> condition)

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<E extends Dom>

next

public E next()

Specified by:

next in interface java.util.Iterator<E extends Dom>

remove

public void remove()

Works after call next() until call hasNext()

Specified by:

remove in interface java.util.Iterator<E extends Dom>

Throws:

java.lang.IllegalStateException - if hasNext() called

peek

public E peek()

Specified by:

peek in interface PeekableIterator<E extends Dom>

Returns:

the current element. Upon iterator creation should return the first element. After Iterator.hasNext() returned false might throw NoSuchElementException.

skipNulls

public static <T> java.util.Iterator<T> skipNulls(java.util.Iterator<? extends T> iterator)

create

public static <T> java.util.Iterator<T> create(java.util.Iterator<? extends T> iterator,
                                               Condition<? super T> condition)

alwaysTrueCondition

public static <T> Condition<T> alwaysTrueCondition(java.lang.Class<T> aClass)

instanceOf

public static <T> FilteringIterator.InstanceOf<T> instanceOf(java.lang.Class<T> aClass)

createInstanceOf

public static <T> java.util.Iterator<T> createInstanceOf(java.util.Iterator<?> iterator,
