org.deegree.model.feature
Class DefaultFeature

java.lang.Object
  org.deegree.model.feature.AbstractFeature
      org.deegree.model.feature.DefaultFeature

All Implemented Interfaces:

Serializable, Feature

public class DefaultFeature
extends AbstractFeature
implements Serializable

Features are, according to the Abstract Specification, digital representations of real world entities. Feature Identity thus refers to mechanisms to identify such representations: not to identify the real world entities that are the subject of a representation. Thus two different representations of a real world entity (say the Mississippi River) will be two different features with distinct identities. Real world identification systems, such as title numbers, while possibly forming a sound basis for an implementation of a feature identity mechanism, are not of themselves such a mechanism.

Method Detail

validate

public void validate()
              throws FeatureException

TODO type checks!

Throws:

FeatureException

getProperties

public FeatureProperty[] getProperties()

Returns all properties of the feature in their original order.

Specified by:

getProperties in interface Feature

Returns:

all properties of the feature

getProperties

public FeatureProperty[] getProperties(QualifiedName name)

Returns the properties of the feature with the given name in their original order.

Specified by:

getProperties in interface Feature

Parameters:

name - name of the properties to look up

Returns:

the properties of the feature with the given name or null if the feature has no property with that name

getDefaultProperty

public FeatureProperty getDefaultProperty(PropertyPath path)
                                   throws PropertyPathResolvingException

Returns the property of the feature identified by the given PropertyPath in their original order. 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 properties of the feature identified by the given PropertyPath or null if the feature has no such properties

Throws:

PropertyPathResolvingException

See Also:

PropertyPath

getDefaultProperty

public FeatureProperty getDefaultProperty(QualifiedName name)

Returns the first property of the feature with the given name.

Specified by:

getDefaultProperty in interface Feature

Parameters:

name - name of the property to look up

Returns:

the first property of the feature with the given name or null if the feature has no such property

getProperties

public FeatureProperty[] getProperties(int index)

Deprecated.

Returns the properties of the feature at the submitted index of the feature type definition.

Specified by:

getProperties in interface Feature

Parameters:

index - index of the properties to look up

Returns:

the properties of the feature at the submitted index

getGeometryPropertyValues

public Geometry[] getGeometryPropertyValues()

Returns the values of all geometry properties of the feature.

Specified by:

getGeometryPropertyValues in interface Feature

Returns:

the values of all geometry properties of the feature, or a zero-length array if the feature has no geometry properties

getDefaultGeometryPropertyValue

public Geometry getDefaultGeometryPropertyValue()

Returns the value of the default geometry property of the feature. If the feature has no geometry property, this is a Point at the coordinates (0,0).

Specified by:

getDefaultGeometryPropertyValue in interface Feature

Returns:

default geometry or Point at (0,0) if feature has no geometry

setProperty

public void setProperty(FeatureProperty property,
