Example 3 with HigherOrderDeclException

use of kodkod.engine.fol2sat.HigherOrderDeclException in project org.alloytools.alloy by AlloyTools.

the class TranslateAlloyToKodkod method execute_commandFromBook.

/**
 * Based on the specified "options", execute one command and return the
 * resulting A4Solution object.
 * <p>
 * Note: it will first test whether the model fits one of the model from the
 * "Software Abstractions" book; if so, it will use the exact instance that was
 * in the book.
 *
 * @param rep - if nonnull, we'll send compilation diagnostic messages to it
 * @param sigs - the list of sigs; this list must be complete
 * @param cmd - the Command to execute
 * @param opt - the set of options guiding the execution of the command
 * @return null if the user chose "save to FILE" as the SAT solver, and nonnull
 *         if the solver finishes the entire solving and is either satisfiable
 *         or unsatisfiable.
 *         <p>
 *         If the return value X is satisfiable, you can call X.next() to get
 *         the next satisfying solution X2; and you can call X2.next() to get
 *         the next satisfying solution X3... until you get an unsatisfying
 *         solution.
