Method Detail

getName

public String getName()

Specified by:

getName in interface NamedKBElement

getURI

public URI getURI()

Specified by:

getURI in interface Entity

getLength

public int getLength()

Description copied from interface: KBElement

Gets the length of this knowledge base element. For instance, A AND B should have length 3 (as three constructs are involved). There are different ways to define the length of an axiom, class description etc., but this method provides a straightforward definition of it.

Specified by:

getLength in interface KBElement

Returns:

The syntactic length of the KB element, defined as the number of syntactic constructs not including brackets.

getArity

public int getArity()

Specified by:

getArity in class Description

toString

public String toString(String baseURI,
                       Map<String,String> prefixes)

Specified by:

toString in interface KBElement

toKBSyntaxString

public String toKBSyntaxString(String baseURI,
                               Map<String,String> prefixes)

Specified by:

toKBSyntaxString in interface KBElement

accept

public void accept(DescriptionVisitor visitor)

Specified by:

accept in class Description

accept

public void accept(KBElementVisitor visitor)

Specified by:

accept in interface KBElement

toManchesterSyntaxString

public String toManchesterSyntaxString(String baseURI,
                                       Map<String,String> prefixes)

Description copied from class: Description

Returns a manchester syntax string of this description. For a reference, see here and here (PDF).

Specified by:

toManchesterSyntaxString in interface KBElement

Specified by:

toManchesterSyntaxString in class Description

Returns:

The manchester syntax string for this description.

compareTo

public int compareTo(NamedClass o)

Specified by:

compareTo in interface Comparable<NamedClass>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
