Constructor Detail

TaskRuntimeMBeanImpl

public TaskRuntimeMBeanImpl(String nameArg,
                            weblogic.management.runtime.RuntimeMBean parentArg,
                            boolean registerNow)
                     throws weblogic.management.ManagementException

Constructor for the RuntimeMBeanDelegate object

Throws:

weblogic.management.ManagementException

Method Detail

cancel

public void cancel()
            throws Exception

Attempts to cancel this task. An Exception is thrown to indicate failure to cancel the task. Not all tasks can be cancelled - do we also need isCancellable()?

Specified by:

cancel in interface TaskRuntimeMBean

Throws:

Exception

getBeginTime

public long getBeginTime()

Returns the time this task was started.

Specified by:

getBeginTime in interface TaskRuntimeMBean

Returns:

The beginTime value

getDescription

public String getDescription()

A description of this task.

Returns a description of this task

Specified by:

getDescription in interface TaskRuntimeMBean

Returns:

The description value

getEndTime

public long getEndTime()

The time this task was completed.

Returns the time this task was completed. Returns -1 if the task is currently running.

Specified by:

getEndTime in interface TaskRuntimeMBean

Returns:

The endTime value

getError

public Exception getError()

Returns an exception describing the error, if any, that occurred while performing this Task.

Specified by:

getError in interface TaskRuntimeMBean

Returns:

The error value

getParentTask

public TaskRuntimeMBean getParentTask()

Returns the task of which this task is a part (see getSubTasks), or null if there is none.

Specified by:

getParentTask in interface TaskRuntimeMBean

Returns:

The parentTask value

See Also:

TaskRuntimeMBean.getSubTasks()

getStatus

public String getStatus()

The status of this task.

Returns the status of this Task.

Specified by:

getStatus in interface TaskRuntimeMBean

Returns:

The status value

getSubTasks

public TaskRuntimeMBean[] getSubTasks()

Returns an array of TaskRuntimes describing a set of parallel tasks which are components of this task. Returns null if this task has no subtasks.

A simple example of a task with subtasks would be one which monitors a user's request to start a cluster; that task should return a set of subtasks indicating the individual server-startup processes which compose the overall cluster-startup task.

Specified by:

getSubTasks in interface TaskRuntimeMBean

Returns:

The subTasks value

isRunning

public boolean isRunning()

Returns true if the Task is still running.

Specified by:

isRunning in interface TaskRuntimeMBean

Returns:

The running value

isSystemTask

public boolean isSystemTask()

Indicates this task was initiated by the server.

Specified by:

isSystemTask in interface TaskRuntimeMBean

Returns:

The systemTask value

printLog

public void printLog(PrintWriter out)

Prints information that was logged during the processing of the task (e.g. server startup log) to the given Writer.

Specified by:

printLog in interface TaskRuntimeMBean

Parameters:

out -

setBeginTime

protected void setBeginTime(long beginTime)

setDescription

protected void setDescription(String description)

setEndTime

protected void setEndTime(long endTime)
