Constructor Detail

DynamicFeatureCollection

public DynamicFeatureCollection(ConnectionDescriptor connectionDescriptor,
                                ConnectionManager connectionManager,
                                FilterQuery spatialQuery)

Method Detail

setFeatureLimit

public void setFeatureLimit(Integer featureLimit)

getFeatureSchema

public FeatureSchema getFeatureSchema()

Description copied from interface: FeatureCollection

Returns information about this FeatureCollection

Specified by:

getFeatureSchema in interface FeatureCollection

Returns:

the types of the attributes of the features in this collection

query

public List<Feature> query(org.locationtech.jts.geom.Envelope envelope)

Description copied from interface: FeatureCollection

A quick search for features, using an envelope comparison.

Specified by:

query in interface FeatureCollection

Parameters:

envelope - the envelope to query against

Returns:

features whose envelopes intersect the given envelope

add

public void add(Feature feature)

Description copied from interface: FeatureCollection

Adds a feature to this collection.

Specified by:

add in interface FeatureCollection

Parameters:

feature - a Feature to add to the end of this collection

addAll

public void addAll(Collection features)

Description copied from interface: FeatureCollection

Adds multiple features to this collection. To be preferred over #add for adding multiple features, because in some systems (like the JUMP Workbench) fewer events will be fired.

Specified by:

addAll in interface FeatureCollection

removeAll

public void removeAll(Collection features)

Description copied from interface: FeatureCollection

Removes multiple features from this collection. To be preferred over #remove for removing multiple features, because in some systems (like the JUMP Workbench) fewer events will be fired.

Specified by:

removeAll in interface FeatureCollection

remove

public void remove(Feature feature)

Description copied from interface: FeatureCollection

Removes a feature from this collection.

Specified by:

remove in interface FeatureCollection

Parameters:

feature - a Feature to remove from this collection

clear

public void clear()

Description copied from interface: FeatureCollection

Removes all features from this collection.

Specified by:

clear in interface FeatureCollection

remove

public Collection<Feature> remove(org.locationtech.jts.geom.Envelope env)

Description copied from interface: FeatureCollection

Removes the features which intersect the given envelope

Specified by:

remove in interface FeatureCollection

Returns:

the removed features

getEnvelope

public org.locationtech.jts.geom.Envelope getEnvelope()

Description copied from interface: FeatureCollection

Returns the bounds of this collection.

Specified by:

getEnvelope in interface FeatureCollection

Returns:

the smallest Envelope enclosing all the Features in this collection

See Also:

FeatureCollection.getEnvelope()

size

public int size()

Description copied from interface: FeatureCollection

Returns the number of features in this collection.

Specified by:

size in interface FeatureCollection

Returns:

the number of features in this collection

isEmpty

public boolean isEmpty()

Description copied from interface: FeatureCollection

Returns whether this collection has no features.

Specified by:

whether or not the size of this collection is 0

getFeatures

public List<Feature> getFeatures()

Description copied from interface: FeatureCollection

Returns an unmodifiable List of the features in this collection

Specified by:
