org.jbpm.graph.exe
Class Token

java.lang.Object
  org.jbpm.graph.exe.Token

All Implemented Interfaces:

java.io.Serializable

---

public class Token
extends java.lang.Object
implements java.io.Serializable

represents one path of execution and maintains a pointer to a node in the ProcessDefinition. Most common way to get a hold of the token objects is with ProcessInstance.getRootToken() or ProcessInstance.findToken(String).

Constructor Detail

Token

public Token()

---

Token

public Token(ProcessInstance processInstance)

creates a root token.

---

Token

public Token(Token parent,
             java.lang.String name)

creates a child token.

Method Detail

signal

public void signal()

provides a signal to the token. this method activates this token and leaves the current state over the default transition.

---

signal

public void signal(java.lang.String transitionName)

provides a signal to the token. this leave the current state over the given transition name.

---

signal

public void signal(Transition transition)

provides a signal to the token. this leave the current state over the given transition name.

---

end

public void end()

ends this token and all of its children (if any). this is the last active (=not-ended) child of a parent token, the parent token will be ended as well and that verification will continue to propagate.

---

end

public void end(boolean verifyParentTermination)

ends this token with optional parent ending verification.

Parameters:

verifyParentTermination - specifies if the parent token should be checked for termination. if verifyParentTermination is set to true and this is the last non-ended child of a parent token, the parent token will be ended as well and the verification will continue to propagate.

---

addComment

public void addComment(java.lang.String message)

---

addComment

public void addComment(Comment comment)

---

getComments

public java.util.List getComments()

---

hasActiveChildren

public boolean hasActiveChildren()

tells if this token has child tokens that have not yet ended.

---

addLog

public void addLog(ProcessLog processLog)

convenience method for adding a process log.

---

startCompositeLog

public void startCompositeLog(CompositeLog compositeLog)

convenience method for starting a composite log. When you add composite logs, make sure you put the endCompositeLog() in a finally block.

---

endCompositeLog

public void endCompositeLog()

convenience method for ending a composite log. Make sure you put this in a finally block.
