Class GeoSpatialServiceFactory.GeoSpatialInputBindingsIterator

java.lang.Object

com.bigdata.rdf.sparql.ast.eval.GeoSpatialServiceFactory.GeoSpatialInputBindingsIterator

All Implemented Interfaces:

ICloseable, ICloseableIterator<IBindingSet>, Iterator<IBindingSet>

Enclosing class:

GeoSpatialServiceFactory

public static class GeoSpatialServiceFactory.GeoSpatialInputBindingsIterator
extends Object
implements ICloseableIterator<IBindingSet>

Iterates a geospatial search over a set of input bindings. This is done incrementally, in a binding by binding fashion.

Method Detail

hasNext

public boolean hasNext()

Checks whether there are more results available.

Specified by:

hasNext in interface Iterator<IBindingSet>

Returns:

next

public IBindingSet next()

Specified by:

next in interface Iterator<IBindingSet>

remove

public void remove()

Specified by:

remove in interface Iterator<IBindingSet>

close

public void close()

Description copied from interface: ICloseableIterator

Closes the iterator, releasing any associated resources. This method MAY be invoked safely if the iterator is already closed. Implementations of this interface MUST invoke ICloseableIterator.close() if Iterator.hasNext() method returns false to ensure that the iterator is closed (and its resources release) as soon as it is exhausted.

Note: Implementations that support Iterator.remove() MUST NOT eagerly close the iterator when it is exhausted since that would make it impossible to remove the last visited statement. Instead they MUST wait for an explicit ICloseableIterator.close() by the application.

Specified by:

close in interface ICloseable

Specified by:

close in interface ICloseableIterator<IBindingSet>
