Class BaseListFilterStream<E>

java.lang.Object
  org.shapelogic.streams.BaseCommonStream<E>
      org.shapelogic.streams.BaseListCommonStream<E>
          org.shapelogic.streams.BaseListIndexedStream1<E,E>
              org.shapelogic.streams.BaseListFilterStream<E>

Type Parameters:

E -

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Iterator<E>, CalcValue<E>, ContextGettable, LazyCalc<E>, RecursiveContext, Predicate<E>, FilterStream<E>, IndexedInputStream1<E,E>, ListFilterStream<E>, ListStream<E>, NumberedStream<E>, Stream<E>, StreamProperties

Direct Known Subclasses:

PredicateListFilterStream

public abstract class BaseListFilterStream<E>
extends BaseListIndexedStream1<E,E>
implements ListFilterStream<E>

This is the abstract class to override to make a ListFilterStream. The code here is the same as what would be in the BaseFilterStream.

BaseListFilterStream

public BaseListFilterStream(NumberedStream<E> inputStream)

Method Detail

invoke

public E invoke(E input,
                int index)

Description copied from interface: IndexedInputStream1

Closure to calculated 1 individual element based on index and input for the same index. Should later just call the invoke on the closure. Maybe this should be moved up later.

Specified by:

invoke in interface IndexedInputStream1<E,E>

index - of element in list

next

public E next()

Description copied from class: BaseListCommonStream

Get next element and advance _current.

Specified by:

next in interface java.util.Iterator<E>

Overrides:

next in class BaseListCommonStream<E>

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<E>

Overrides:

hasNext in class BaseListCommonStream<E>

get

public E get(int index)

Description copied from class: BaseListCommonStream

Get next element without advancing _current.

Specified by:

get in interface NumberedStream<E>

Overrides:

get in class BaseListCommonStream<E>

Returns:
