Method Detail

features

public FeatureIterator<Feature> features()

Description copied from class: BaseFeatureCollection

Subclasses required to implement this method to traverse FeatureCollection contents.

Note that FeatureIterator#close() is available to clean up after any resource use required during traversal.

Specified by:

features in interface FeatureCollection<FeatureType,Feature>

Specified by:

features in class BaseFeatureCollection<FeatureType,Feature>

Returns:

A FeatureIterator.

getSchema

public FeatureType getSchema()

Description copied from interface: FeatureCollection

The schema for the child feature members of this collection.

Represents the most general FeatureType in common to all the features in this collection.

• For a collection backed by a shapefiles (or database tables) the FeatureType returned by getSchema() will complete describe each and every child in the collection.
• For mixed content FeatureCollections you will need to check the FeatureType of each Feature as it is retrived from the collection
• The degenerate case returns the "_Feature" FeatureType, where the only thing known is that the contents are Features.

Specified by:

getSchema in interface FeatureCollection<FeatureType,Feature>

Overrides:

getSchema in class BaseFeatureCollection<FeatureType,Feature>

Returns:

FeatureType describing the "common" schema to all child features of this collection

subCollection

public FeatureCollection<FeatureType,Feature> subCollection(Filter filter)

Description copied from class: BaseFeatureCollection

Convenience implementation that just wraps this collection into a FilteringFeatureCollection. Subclasses might want to override this in case the filter can be cascaded to their data sources.

Specified by:

subCollection in interface FeatureCollection<FeatureType,Feature>

Overrides:

subCollection in class BaseFeatureCollection<FeatureType,Feature>

Returns:

SimpleFeatureCollection identified as subset.
