Method Detail

getDelegate

public FeatureIterator<F> getDelegate()

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<F extends Feature>
Returns:
true if more Features exist, false otherwise.

next

public F next()
Description copied from interface: FeatureIterator
Get the next Feature in this iteration.

Specified by:
next in interface FeatureIterator<F extends Feature>
Returns:
The next Feature

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 Closeable
Specified by:
