## org.jbpm.persistence.processinstance
Class ProcessInstanceInfo

    java.lang.Object
      org.jbpm.persistence.processinstance.ProcessInstanceInfo

    public class ProcessInstanceInfo

extends Object

This is the object that contains the marshalled byte stream of information representing the ProcessInstance class. Because of Hibernate 3.3.x/3.4.x <-> 4.x compatibility issues, the mapping for this class has been moved to

Constructor Detail

### ProcessInstanceInfo

    protected ProcessInstanceInfo()

### ProcessInstanceInfo

    public ProcessInstanceInfo(ProcessInstance processInstance)

### ProcessInstanceInfo

    public ProcessInstanceInfo(ProcessInstance processInstance,
                               Environment env)

Method Detail

### getProcessInstanceId

    public Long getProcessInstanceId()

  Added in order to satisfy Hibernate AND the JBPMorm.xml:
  - Hibernate needs getter/setters for a the field that's mapped.
    - (field access is inefficient/dangerous, and not necessary)
  - The JBPMorm.xml queries reference .processInstanceId as well.
  If we mapped the field using 'name="id"', the queries would thus fail. So instead of that, we just add the getters and use 'name="processInstanceId"'.

  Returns:
    The processInstanceId field value.

### setProcessInstanceId

    public void setProcessInstanceId(Long processInstanceId)

### getId

    public Long getId()

### setId

    public void setId(Long processInstanceId)

### getProcessId

    public String getProcessId()

### getStartDate

    public Date getStartDate()

### getLastModificationDate

    public Date getLastModificationDate()

### getLastReadDate

    public Date getLastReadDate()

### updateLastReadDate

    public void updateLastReadDate()

### getState

    public int getState()

### getProcessInstance

    public ProcessInstance getProcessInstance(org.drools.common.InternalKnowledgeRuntime kruntime,
                                              Environment env)

### update

    public void update()

  Adding @PrePersist breaks things, because:
  - We retrieve/generate the marshaller (see below).
  - ..and the marshaller retrieves the context instance
  - ..which actually (re)sets all variables in `VariableScopeInstance`.setContextInstanceContainer(...)
  - This of course causes `ProcessEventSupport`.fireBeforeVariableChanged(...) to fire.
  - Then the `JPAWorkingMemoryDbLogger` ends up logging a variable change -- but the associated process instance hasn't been persisted yet.
  - So the variable instance change is associated with process instance "0"
  - ...and can never be retrieved, because "0" is not a valid id.
  Normally, the variable change is logged after the following method has completed.

### equals

    public boolean equals(Object obj)

  Overrides:
    `equals` in class `Object`

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `Object`

### getVersion

    public int getVersion()

### getEventTypes

    public Set<String> getEventTypes()

### getProcessInstanceByteArray

    public byte[] getProcessInstanceByteArray()

### clearProcessInstance

    public void clearProcessInstance()

### getEnv

    public Environment getEnv()

### setEnv

    public void setEnv(Environment env)
