Method Detail

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.

Returns:

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

toString

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

toKBSyntaxString

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

toManchesterSyntaxString

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

getLang

public String getLang()

Returns:

the lang

hasLang

public boolean hasLang()

Returns:

the hasLang

accept

public void accept(KBElementVisitor visitor)

toString

public String toString()

Overrides:

toString in class Object

compareTo

public int compareTo(Constant o)
