Method hasMoreSolutions

src/main/java/org/jpl7/Query.java:339–345

This method returns true if JPL was able to initiate a "call" of this Query within a Prolog engine. It is designed to be used with the nextSolution() method to retrieve one or more substitutions in the form of Maps. To iterate through all the solutions to a Query, for example, one might write

()

	 * @return true if the Prolog query succeeds; otherwise false.
