Constructor Details

FeatureImpl

public FeatureImpl(Collection<Property> properties,
 AttributeDescriptor desc,
 FeatureId id)

Create a Feature with the following content.

Parameters:

properties - Collectio of Properties (aka Attributes and/or Associations)

desc - Nested descriptor

id - Feature ID

FeatureImpl

public FeatureImpl(Collection<Property> properties,
 FeatureType type,
 FeatureId id)

Create a Feature with the following content.

Parameters:

properties - Collectio of Properties (aka Attributes and/or Associations)

type - Type of feature to be created

id - Feature ID

Method Details

getType

public FeatureType getType()

Description copied from interface: Property

The type of the property.

The type contains information about the value or content of the property such as its java class.

This value is also available via getDescriptor().getType().

Specified by:

getType in interface Attribute

Specified by:

getType in interface ComplexAttribute

Specified by:

getType in interface Feature

Specified by:

getType in interface Property

Overrides:

getType in class ComplexAttributeImpl

Returns:

The property type.

See Also:

• Property.getType()

getIdentifier

public FeatureId getIdentifier()

Description copied from interface: Attribute

Unique Identifier for the attribute.

This value is non-null in the case that getType().isIdentifiable() is true.

Specified by:

getIdentifier in interface Attribute

Specified by:

getIdentifier in interface Feature

Overrides:

getIdentifier in class AttributeImpl

Returns:

A unique identifier for the attribute, or null if the attribute is non-identifiable.

getBounds

public BoundingBox getBounds()

Get the total bounds of this feature which is calculated by doing a union of the bounds of each geometry this feature is associated with.

Specified by:

getBounds in interface Feature

Returns:

An Envelope containing the total bounds of this Feature.

TODO:

REVISIT: what to return if there are no geometries in the feature? For now we'll return a null envelope, make this part of interface? (IanS - by OGC standards, all Feature must have geom)

getDefaultGeometryProperty

public GeometryAttribute getDefaultGeometryProperty()

Description copied from interface: Feature

The default geometric attribute of the feature.

This method returns null in the case where no such attribute exists.

Specified by:

getDefaultGeometryProperty in interface Feature

Returns:

The default geometry attribute, or null.

setDefaultGeometryProperty

public void setDefaultGeometryProperty(GeometryAttribute defaultGeometry)

Description copied from interface: Feature

Sets the default geometric attribute of the feature.

This value must be an attribute which is already defined for the feature. In other words, this method can not be used to add a new attribute to the feature.

Specified by:

setDefaultGeometryProperty in interface Feature

Parameters:

defaultGeometry - The new geomtric attribute.
