Examples of org.activiti.engine.runtime.ExecutionQuery

org.activiti.engine.runtime.ExecutionQuery
Allows programmatic querying of {@link Execution}s. @author Joram Barrez @author Frederik Heremans

    
    Calendar oneYearAgo = Calendar.getInstance();
    oneYearAgo.add(Calendar.YEAR, -1);    
    
    // Query on single short variable, should result in 2 matches
    ExecutionQuery query = runtimeService.createExecutionQuery().variableValueEquals("dateVar", date1);
    List<Execution> executions = query.list();
    assertNotNull(executions);
    assertEquals(2, executions.size());
  
    // Query on two short variables, should result in single value
    query = runtimeService.createExecutionQuery().variableValueEquals("dateVar", date1).variableValueEquals("dateVar2", date2);
    Execution execution = query.singleResult();
    assertNotNull(execution);
    assertEquals(processInstance2.getId(), execution.getId());
    
    // Query with unexisting variable value
    Date unexistingDate = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss").parse("01/01/1989 12:00:00");
