Method Detail

getLiteral

java.lang.String getLiteral()

Gets the string literal that this constant represents.

isTyped

boolean isTyped()

Determines if this constant is typed (i.e. an instance of OWLTypedConstant)

Returns:

true if the constant is typed, or false if the constant is untyped.

asOWLTypedConstant

OWLTypedConstant asOWLTypedConstant()

If this constant is a typed constant (i.e. if the isTyped method returns true then this method obtains this constant as a typed constant. If isTyped returns false because this constant is not a typed constant then calling this method will cause an OWLRuntimeException to be thrown.

asOWLUntypedConstant

OWLUntypedConstant asOWLUntypedConstant()

If this constant is an untyped constant (i.e. if the isTyped method returns false then this method obtains this constant as an untyped constant. If the isTyped method returns true because this method is a typed constant, then calling this method will cause an OWLRuntimeException to be thrown.
