List of flushVariableCache() Examples

Examples of flushVariableCache()

org.camunda.bpm.engine.cdi.BusinessProcess.flushVariableCache()

This method allows to flush the cached variables to the Task or Execution.

If a Task instance is currently associated, the variables will be flushed using {@link TaskService#setVariables(String,Map)}
If an Execution instance is currently associated, the variables will be flushed using {@link RuntimeService#setVariables(String,Map)}
If neither a Task nor an Execution is currently associated, ProcessEngineCdiException is thrown.

A successful invocation of this method will empty the variable cache.

If this method is called from an active command (ie. from inside a Java Delegate). {@link ProcessEngineCdiException} is thrown.

@throws ProcessEngineCdiException if called from a process engine command or if neither a Task nor an Execution is associated.

    businessProcess.startTask(task.getId());


    businessProcess.setVariableLocal("aVariableName", "aVariableValue");


    // Flushing and re-getting should retain the value (CAM-1806):
    businessProcess.flushVariableCache();
    assertTrue(businessProcess.getVariableLocalCache().isEmpty());
    assertEquals("aVariableValue", businessProcess.getVariableLocal("aVariableName"));
  }


  @Test

  public void testFlushVariableCache() {
    BusinessProcess businessProcess = getBeanInstance(BusinessProcess.class);


    // cannot flush variable cache in absence of an association:
    try {
      businessProcess.flushVariableCache();
      fail("exception expected!");


    } catch (ProcessEngineCdiException e) {
      assertEquals("Cannot flush variable cache: neither a Task nor an Execution is associated.", e.getMessage());


    // the local variable is not yet present in the execution:
    assertNull(runtimeService.getVariable(businessProcess.getExecutionId(), "aVariableLocalName"));


    // flush the cache
    businessProcess.flushVariableCache();


    // the variable is flushed to the execution
    assertNotNull(runtimeService.getVariable(businessProcess.getExecutionId(), "aVariableName"));


    // the local variable is flushed to the execution
