public interface Predicate

The Predicate class currently represents (1) first-order predicts, (2) function symbols, and (3) logical operators (e.g. join, left join)

Method Summary

Modifier and Type	Method and Description
int	getArity() Get the number of elements of the predicate.
String	getName() Get the name of the predicate.

Method Detail

getName

String getName()

Get the name of the predicate. In practice, the predicate name is constructed as a URI to indicate a unique resource.

Returns:

the resource identifier (URI).

getArity

int getArity()

Get the number of elements of the predicate.

Returns:

an integer number.
