Implementations must block until tool execution is complete, and must re-throw any java.lang.InterruptedException caught, because this exception informs the ToolAgent.invokeApplication method that the tool has been terminated. Implementations must update the values of INOUT and OUT parameters if they changed as a result of tool execution. There is no need to clear IN parameter values, because this is done automatically by ToolAgent.invokeApplication . Parameters:   ti - Tool invocation details and parameters. The tool's exit code. One of AbstractToolAgent.EXIT_NORMAL,AbstractToolAgent.EXIT_CANCEL. throws:   InterruptedException - if AbstractToolAgent.terminateApp() was called. throws:   InvocationTargetException - If any other exception occurred whileinvoking the tool. getWorkflowContext protected static WorkflowContext getWorkflowContext()(Code) Describes the workflow context in which the tool is being invoked. N.B. This method will return null if the tool agent was invoked by a remote client. The workflow context, if known. invokeApplication final public int invokeApplication(ToolInvocation ti) throws InvocationTargetException(Code) renderInvocationScript public void renderInvocationScript(ToolInvocation ti, Writer writer) throws IOException(Code) requestAppStatus public int requestAppStatus()(Code) terminateApp final public void terminateApp()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
