Constructor Detail

AbstractFeature

AbstractFeature(String id,
                FeatureType featureType)

Parameters:

id -

featureType -

AbstractFeature

AbstractFeature(String id,
                FeatureType featureType,
                FeatureProperty owner)

Parameters:

id -

featureType -

Method Detail

getDescription

public String getDescription()

Description copied from interface: Feature

Returns the description of the feature.

Specified by:

getDescription in interface Feature

Returns:

the description of the feature.

getName

public QualifiedName getName()

Description copied from interface: Feature

Returns the qualified name of the feature.

Specified by:

getName in interface Feature

Returns:

the qualified name of the feature

getBoundedBy

public Envelope getBoundedBy()
                      throws GeometryException

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

Returns:

the envelope / bounding box of the feature

Throws:

GeometryException

setEnvelopesUpdated

public void setEnvelopesUpdated()

Signals that the envelopes of the geometry properties have been updated.

Specified by:

setEnvelopesUpdated in interface Feature

getOwner

public FeatureProperty getOwner()

Description copied from interface: Feature

Returns the owner of the feature. This is the feature property that has this feature as value or null if this feature is a root feature.

Specified by:

getOwner in interface Feature

Returns:

the owner of the feature, or null if the feature does not belong to a feature property

getId

public String getId()

returns the id of the Feature. the id has to be a name space that must be unique for each feature. use the adress of the datasource in addition to a number for example .

Specified by:

getId in interface Feature

Returns:

the id of the feature

setId

public void setId(String fid)

Description copied from interface: Feature

Sets the id of the feature.

Specified by:

setId in interface Feature

Parameters:

fid - the id of the feature to be set

getFeatureType

public FeatureType getFeatureType()

returns the FeatureType of this Feature

Specified by:

getFeatureType in interface Feature

Returns:

the feature type of this feature

setFeatureType

public void setFeatureType(FeatureType ft)

Sets the feature type of this feature.

Specified by:

setFeatureType in interface Feature

Parameters:

ft - feature type to set

resetBounds

protected void resetBounds()

resets the envelope of the feature so the next call of getBounds() will force a re-calculation

getAttribute

public String getAttribute(String name)

Returns the attribute value of the attribute with the specified name.

Specified by:

getAttribute in interface Feature

Parameters:

name - name of the attribute

Returns:

the attribute value

getAttributes

public Map<String,String> getAttributes()

Returns all attributes of the feature.

Specified by:

getAttributes in interface Feature

Returns:

all attributes, keys are names, values are attribute values

setAttribute

public void setAttribute(String name,
                         String value)

Sets the value of the attribute with the given name.

Specified by:

setAttribute in interface Feature

Parameters:

name - name of the attribute

value - value to set

clone

public Object clone()
             throws CloneNotSupportedException

Specified by:

clone in interface Feature

Overrides:

clone in class Object

Returns:

a shallow clone of a feature. Property values will not be cloned except for properties that are features (DefaultFeature) or feature collections (DefaultFeatureCollection)

Throws:

CloneNotSupportedException
