Method Detail

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

Overrides:

toManchesterSyntaxString in class DatatypeValueRestriction

Returns:

The manchester syntax string for this description.

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.

getStringValue

public String getStringValue()

toKBSyntaxString

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

Specified by:

toKBSyntaxString in interface KBElement

Overrides:

toKBSyntaxString in class DatatypeValueRestriction
