Class FeatureTupleCollection

java.lang.Object
  org.deegree.model.feature.AbstractFeature
      org.deegree.model.feature.AbstractFeatureCollection
          org.deegree.model.feature.FeatureTupleCollection

All Implemented Interfaces:

Serializable, Feature, FeatureCollection

public class FeatureTupleCollection
extends AbstractFeatureCollection
implements Serializable

Represents a FeatureCollection that only contains wfs:featureTuple elements (as introduced by the draft WFS 1.2 spec).

NOTE: Some concepts of ordinary feature collections (like adding and removing of features) do not match well to this special kind of feature collection, mostly because it uses a FeatureArrayPropertyType for the wfs:featureTuple element. Thus, many methods inherited from AbstractFeatureCollection have no clear semantic and are not available.

Constructor Detail

FeatureTupleCollection

FeatureTupleCollection(String id,
                       List<Feature[]> tuples,
                       int tupleLength)

Method Detail

clear

public void clear()

Description copied from interface: FeatureCollection

removes all features from a collection

Specified by:

clear in interface FeatureCollection

getTuple

public Feature[] getTuple(int index)

Returns the feature tuple at the given index.

Parameters:

index -

Returns:

the feature tuple at the given index

numTuples

public int numTuples()

Returns the number of feature tuples contained in this collection.

Returns:

the number of feature tuples contained in this collection

tupleLength

public int tupleLength()

Returns the length (number of features) of each tuple.

Returns:

the length (number of features) of each tuple.

getBoundedBy

public Envelope getBoundedBy()
                      throws GeometryException

Description copied from class: AbstractFeature

Returns the envelope / boundingbox of the feature. The bounding box will be created in a recursion. That means if a property of the feature (a) contains another feature (b) the bounding box of b will be merged with the bounding box calculated from the geometry properties of a. A feature has no geometry properties and no properties that are features (and having a bounding box theirself) null will be returned.

Specified by:

getBoundedBy in interface Feature

Overrides:

getBoundedBy in class AbstractFeature

Returns:

the envelope / bounding box of the feature

Throws:

GeometryException

size

public int size()

Description copied from interface: FeatureCollection

returns the number of features within the collection

Specified by:

size in interface FeatureCollection

add

public void add(Feature feature)

Description copied from interface: FeatureCollection

adds a feature to the collection

Specified by:

add in interface FeatureCollection

getFeature

public Feature getFeature(int index)

Description copied from interface: FeatureCollection

returns the feature at the submitted index

Specified by:

getFeature in interface FeatureCollection

getFeature

public Feature getFeature(String id)

Description copied from interface: FeatureCollection

returns the feature identified by it's id

Specified by:

getFeature in interface FeatureCollection

iterator

public Iterator iterator()

Description copied from interface: FeatureCollection

returns an Iterator on the feature contained in a collection

Specified by:

iterator in interface FeatureCollection

Returns:

an Iterator on the feature contained in a collection

remove

public Feature remove(Feature feature)

Description copied from interface: FeatureCollection

removes the submitted feature from the collection

Specified by:

remove in interface FeatureCollection

remove

public Feature remove(int index)

Description copied from interface: FeatureCollection

removes the feature at the submitted index from the collection

Specified by:

remove in interface FeatureCollection

toArray

public Feature[] toArray()

Description copied from interface: FeatureCollection

returns an array of all features

Specified by:

toArray in interface FeatureCollection

addProperty

public void addProperty(FeatureProperty property)

Description copied from interface: Feature

Adds the given property to the feature's properties. The position of the property is determined by the feature type. If the feature already has a property with this name, it is inserted behind it.

Specified by:

addProperty in interface Feature

Parameters:

property - property to insert

getDefaultProperty

public FeatureProperty getDefaultProperty(PropertyPath path)
                                   throws PropertyPathResolvingException

Description copied from interface: Feature

Returns the property of the feature identified by the given PropertyPath. NOTE: Current implementation does not handle multiple properties (on the path) or index addressing in the path.

Specified by:

getDefaultProperty in interface Feature

Parameters:

path - the path of the property to look up

Returns:

the property of the feature identified by the given PropertyPath

Throws:

PropertyPathResolvingException

See Also:

PropertyPath

Description copied from interface: Feature

Removes the properties with the given name.

Specified by:

removeProperty in interface Feature

Parameters:

propertyName - name of the properties to remove

replaceProperty

public void replaceProperty(FeatureProperty oldProperty,
                            FeatureProperty newProperty)

Description copied from interface: Feature

Replaces the given property with a new one.

Specified by:

Parameters:

oldProperty - property to be replaced

newProperty - new property

setProperty

public void setProperty(FeatureProperty property,
                        int index)

Description copied from interface: Feature

Sets the value for the given property. The index is needed to specify the occurences of the property that is to be replaced. Set to 0 for properties that may only occur once.

Specified by:

setProperty in interface Feature

Parameters:

property - property name and the property's new value

index - position of the property that is to be replaced
