Method Details

transformQueryToIdsOnly

protected Query transformQueryToIdsOnly()

Build the query for execute on index source partial Implementation manages pagination by itself, so remove bounds from query

Overrides:

transformQueryToIdsOnly in class IndexedMappingFeatureIterator

Returns:

Query

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.)

Returns:

true if more Features exist, false otherwise.

next

public Feature next()

Description copied from interface: FeatureIterator

Get the next Feature in this iteration.

Returns:

The next Feature

close

public void close()

Description copied from interface: FeatureIterator

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