Method Detail

hasNext

boolean hasNext()
         throws BackingStoreException

Method inherited from Iterator that indicates whether there's another feature available.

Because no exceptions are thrown in the Iterator interface, any I/O exceptions that occur while executing this method must be wrapped in a BackingStoreException before being thrown.

Specified by:

hasNext in interface java.util.Iterator<Feature>

Throws:

BackingStoreException - If an error occurs while fetching the feature.

remove

void remove()
     throws java.lang.UnsupportedOperationException,
            BackingStoreException

If supported by the underlying FeatureCollection, invoking this method will remove the last Feature returned by Iterator.next().

Specified by:

remove in interface java.util.Iterator<Feature>

Throws:

java.lang.UnsupportedOperationException - If removing items is not supported by the underlying collection.

BackingStoreException - If an error occurs while removing the feature.

close

void close()
    throws java.io.IOException

If applicable, closes any connection to a persistent store that backs this iterator.

Throws:

java.io.IOException - if an error occurs while closing the iterator.
