Accessing process instance variables from ProcessInstanceQuery

Question

What is the proper way to query process instance variables in Camunda?

In Activiti there is a getProcessVariables() method available on the org.activiti.engine.runtime.ProcessInstance but it was removed from org.camunda.bpm.engine.runtime.ProcessInstance.

Answer 1

camunda introduced a new, separate query for process instance variables:

VariableInstance v = 
  runtimeService.createVariableInstanceQuery()
    .processInstanceIdIn(pId)
    .variableName("myVariable")
  .singleResult();
