PostFilteringMappingFeatureIterator

All Implemented Interfaces:

Closeable, AutoCloseable, Iterator<Feature>, IMappingFeatureIterator, FeatureIterator<Feature>

public class PostFilteringMappingFeatureIterator
extends Object
implements IMappingFeatureIterator

An extension to DataAccessMappingFeatureIterator where filter is present. Unlike with FilteringMappingFeatureIterator The filter is applied on the complex feature

Method Detail

close

public void close()

Description copied from interface: FeatureIterator

Closes this iterator and releases any system resources associated with it.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface FeatureIterator<Feature>

getFilteredNext

protected Feature getFilteredNext()

hasNext

public boolean hasNext()

Description copied from interface: FeatureIterator

Does another Feature exist in this Iteration.

Iterator defin: Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface FeatureIterator<Feature>

Specified by:

hasNext in interface Iterator<Feature>

Returns:

true if more Features exist, false otherwise.

next

public Feature next()

Description copied from interface: FeatureIterator

Get the next Feature in this iteration.

Specified by:

next in interface FeatureIterator<Feature>

Specified by:

next in interface Iterator<Feature>

Returns:

The next Feature

remove

public void remove()

Specified by:

remove in interface Iterator<Feature>
