Method Detail

addElement

boolean addElement(Object key)

Adds an element to this TaskRunnable.

Parameters:

key - Element to be added to this TaskRunnable

Returns:

a boolean to indicate whether the add success

removeElement

boolean removeElement(Object key)

Removes an element from this TaskRunnable.

Parameters:

key - Element to be removed from this TaskRunnable

Returns:

A boolean to indicate whether the remove success

isEmpty

boolean isEmpty()

Indicates whether this TaskRunnable is empty.

Returns:

A boolean to indicate whether this TaskRunnable is empty

setNext

void setNext(TaskRunnable task)

Sets the TaskRunnable next to this TaskRunnable in the linked-list. It is for internal use only.

Parameters:

task - The next TaskRunnable

setPrevious

void setPrevious(TaskRunnable task)

Sets the TaskRunnable previous to this TaskRunnable in the linked-list. It is for internal use only.

Parameters:

task - The previous TaskRunnable

setHeadTask

void setHeadTask(HeadTaskRunnable headTask)

Sets the head task for this linkable TaskRunnable. The head task of this TaskRunnable will be set. HeadTask works as a lock when the elements of the linked task is going to be changed. It is for internal use only.

Parameters:

headTask - The HeadTaskRunnable

getHeadTask

HeadTaskRunnable getHeadTask()

Returns the head task for this linkable TaskRunnable. The head task of this TaskRunnable will be returned or null if it doesn't have one. HeadTask works as a lock when the elements of the linked task is going to be changed.

Returns:

The head task of this linkable TaskRunnable

getRunPeriod

long getRunPeriod()

Returns the run period of this TaskRunnable.

Returns:

A long value to indicate the run period

next

TaskRunnable next()

Returns the TaskRunnable next to this TaskRunnable in the linked-list.

Returns:

next TaskRunnable object or null if it is not set

previous

TaskRunnable previous()

Returns the TaskRunnable previous to this TaskRunnable in the linked-list.

Returns:

previous TaskRunnable object or null if it is not set

scheduledExecutionTime

long scheduledExecutionTime()

Returns the scheduled time of this TaskRunnable.

Returns:

A long value indicate the time this TaskRunnable is scheduled, or -1 if it is not scheduled yet

cancel

void cancel()

Cancel the task from scheduled Timer.
