Constructor Detail

GenericFeatureCollection

public GenericFeatureCollection(FeatureCollectionType ft,
                                String fid,
                                List<Property> props,

                                GMLVersion version)

Creates a new GenericFeatureCollection instance with type information and content specified using properties.

Parameters:

ft - feature collection type, must not be null

fid - feature id, may be null

props - properties (including feature member/feature member array properties), must not be null

version - GML version (determines the names/types of the standard properties), or null (then no standard GML properties are allowed)

GenericFeatureCollection

public GenericFeatureCollection(String fid,
                                Collection<Feature> memberFeatures)

Creates a new GenericFeatureCollection instance without type information that contains the given features.

Parameters:

fid -

memberFeatures -

GenericFeatureCollection

public GenericFeatureCollection()

Creates a new empty GenericFeatureCollection instance without type information.

Method Detail

getName

public QName getName()

Description copied from interface: Feature

Returns the name of the feature.

In a GML representation of the feature, this corresponds to the feature element's name.

Specified by:

getName in interface Feature

Overrides:

getName in class AbstractFeature

Returns:

the name of the feature instance, never null

getProperties

public Property[] getProperties()

Description copied from interface: Feature

Returns all properties in order, excluding standard GML properties such as gml:name.

Returns:

all properties, excluding standard GML properties, may be empty, but never null

setProperties

public void setProperties(List<Property> props)
                   throws IllegalArgumentException

Description copied from interface: Feature

Called during construction to initialize the properties of the feature.

Throws:

IllegalArgumentException - if the property names or values are not compatible with the feature type

iterator

public Iterator<Feature> iterator()

add

public boolean add(Feature e)

addAll

public boolean addAll(Collection<? extends Feature> c)

clear

public void clear()

contains

public boolean contains(Object o)

containsAll

public boolean containsAll(Collection<?> c)

isEmpty

public boolean isEmpty()

remove

public boolean remove(Object o)

removeAll

public boolean removeAll(Collection<?> c)

retainAll

public boolean retainAll(Collection<?> c)

size

public int size()

toArray

public Object[] toArray()

toArray

setPropertyValue

public void setPropertyValue(QName propName,
                             int occurrence,
                             TypedObjectNode value)

Description copied from interface: Feature

Sets the value of a specific occurrence of a property with a given name (or removes the property feature).

Parameters:

propName - property name

occurrence - index of the property, starting with zero. If the property is not a multi-property (i.e. maxOccurs=1), this is always zero.

value - new value of the property or null (removes the property)

getProperties

public Property[] getProperties(QName propName)

Description copied from interface: Feature

Returns the properties with the given name, in order.

Parameters:

propName - name of the requested properties

Returns:

the properties with the given name, in order, may be empty, but never null

getProperty

public Property getProperty(QName propName)

Description copied from interface: Feature

Returns the property with the given name.

Parameters:

propName - name of the requested property

Returns:

the property with the given name

getGeometryProperties

public Property[] getGeometryProperties()

Description copied from interface: Feature

Returns all geometry-valued properties in order.

Returns:

all geometry properties
