Example 1 with EventBInvariant

use of de.prob.model.eventb.EventBInvariant in project prob2 by bendisposto.

the class MachineXmlHandler method addInvariant.

private void addInvariant(final Attributes attributes) {
    String source = attributes.getValue("org.eventb.core.source");
    String internalName = source.substring(source.lastIndexOf('#') + 1, source.length());
    internalName = internalName.replace("\\", "");
    String filePath = source.substring(0, source.indexOf('|'));
    String machineName = filePath.substring(filePath.lastIndexOf('/') + 1, filePath.lastIndexOf('.'));
    if (machineName.equals(machine.getName())) {
        String label = attributes.getValue("org.eventb.core.label");
        String predicate = attributes.getValue("org.eventb.core.predicate");
        boolean theorem = "true".equals(attributes.getValue("org.eventb.core.theorem"));
        EventBInvariant inv = new EventBInvariant(label, predicate, theorem, typeEnv);
        invariants.add(inv);
        invariantCache.get(machine.getName()).put(internalName, inv);
    } else {
