Constructor Detail

AttributeInstance

public AttributeInstance(java.lang.String attribute_name,
                         java.lang.String source_label,
                         boolean is_inferred)

Creates a new instance of an attribute instance to be added to a semantic network, thereby associating it with a concept instance.

Parameters:

attribute_name - - the attribute name

source_label - - the source label

is_inferred - - whether this attribute instance is inferred

ConceptInstance, SemanticNetwork.addAttributeInstance(SemanticNetwork.AttributeInstance)

AttributeInstance

public AttributeInstance(java.lang.String source_label,
                         java.lang.String attribute_name)

Creates a new, non-inferred instance of an attribute instance to be added to a semantic network, thereby associating it with a concept instance.

Parameters:

source_label - - the source label

attribute_name - - the attribute name

ConceptInstance, SemanticNetwork.addAttributeInstance(SemanticNetwork.AttributeInstance)

AttributeInstance

public AttributeInstance(java.lang.String attribute_name,
                         java.lang.String source_label,
                         java.lang.String frame_name,
                         boolean is_inferred)

Creates a new instance of an attribute instance to be added to a semantic network, thereby associating it with a concept instance.

Parameters:

attribute_name - - the attribute name

source_label - - the source label

frame_name - - the frame this attribute is associated with

is_inferred - - whether this attribute instance is inferred

See Also:

getFrameName(), ConceptInstance, SemanticNetwork.addAttributeInstance(SemanticNetwork.AttributeInstance)

Method Detail

getAttributeName

public java.lang.String getAttributeName()

Returns the attribute name of this attribute instance.

Returns:

the attribute name

getClone

public AttributeInstance getClone()

Returns a deep clone of this attribute instance. All fields are copied by value.

Returns:

the clone

getFrameName

public java.lang.String getFrameName()

Returns the frame name of this attribute instance. A frame is an arbitrary collection of attributes sharing the same frame name. It is intended to improve clarity in the rendering of a semantic network by grouping related attributes into a single graphical node, thereby reducing the number of nodes and arcs.

Returns:

the frame name, or an empty string if none was set in the constructor

getSourceLabel

public java.lang.String getSourceLabel()

Returns the unique label of the concept instance that roots this attribute instance.

Returns:

the source label

isInferred

public boolean isInferred()

Returns whether this attribute instance is inferred.

Returns:

the infer state

serialize

public java.lang.String serialize()

Returns a serialized representation of this attribute instance.

Returns:

the serialization

setSemanticNetwork

protected void setSemanticNetwork(SemanticNetwork semantic_network)

Sets the semantic network this attribute instance was added to.

Parameters:

semantic_network - - the semantic network

toString

public java.lang.String toString()

Returns a string representation of this object.

Overrides:

toString in class java.lang.Object

Returns:

the String representation
