Constructor Detail

FeatureNode

FeatureNode(FeatureGraph graph,
            FeatureId fid,
            Map<MappedFeaturePropertyType,List<FeatureId>> subFeatureProperties,
            Set<FeatureId> superFeatures)

Creates a new FeatureNode instance that represents the feature with the given FeatureId.

Parameters:

graph - FeatureGraph that the node belongs to

fid - id of the represented feature

subFeatureProperties - complex property types of the feature and the ids of the subfeatures that they contain

superFeatures - ids of all features that contain the represented feature as a subfeature

Method Detail

getFid

FeatureId getFid()

Returns the associated FeatureId.

Returns:

the associated FeatureId

getSubFeatureIds

Set<FeatureId> getSubFeatureIds()

Returns the ids of all subfeatures of the represented feature.

Returns:

the ids of all subfeatures of the represented feature

getSubFeatureIds

List<FeatureId> getSubFeatureIds(MappedFeaturePropertyType pt)

Returns the ids of all subfeatures stored in the specified property of the represented feature.

Returns:

the ids of all subfeatures of the represented feature

getSubFeatures

List<FeatureNode> getSubFeatures()

Returns all subfeatures of the represented feature.

Returns:

all subfeatures of the represented feature

getSuperFeatureIds

Set<FeatureId> getSuperFeatureIds()

Returns the ids of all superfeatures of the represented feature (features that contain the represented feature as a subfeature).

Returns:

the ids of all superfeatures of the represented feature

isDeletable

boolean isDeletable()

Returns whether the represented feature may be deleted.

Returns:

true, if the represented feature may be deleted, otherwise false

markAsUndeletable

void markAsUndeletable()

Marks this feature as undeletable. This is also applied to all it's descendant subfeatures.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

String toString(String indent,
                Set<FeatureNode> printedNodes)

Generates an indented string representation of this FeatureNode and all it's descendant subfeatures.

Parameters:

indent - current indentation (string consisting of spaces)

printedNodes - FeatureNodes that have all ready been encountered (to avoid endless recursion)

Returns:

an indented string representation
