ClippedFeatureIterator

public ClippedFeatureIterator(SimpleFeatureIterator delegate,
 Geometry clip,
 SimpleFeatureType schema,
 boolean preserveZ)

Method Details

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<SimpleFeature>

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<SimpleFeature>

Returns:

true if more Features exist, false otherwise.

prepareBuilderForNextFeature

protected boolean prepareBuilderForNextFeature(SimpleFeature f)

next

public SimpleFeature next()
                   throws NoSuchElementException

Description copied from interface: FeatureIterator

Get the next Feature in this iteration.

Specified by:

next in interface FeatureIterator<SimpleFeature>

Returns:

The next Feature

Throws:

NoSuchElementException - If no more Features exist.

hasElevations

protected boolean hasElevations(CoordinateSequence seq)
