Constructor Detail

CronTask

public CronTask(java.lang.String strClassName,
                java.lang.String strMethodName,
                java.lang.String[] strParams)

Constructor of a task.

Parameters:

strClassName - Name of the Class

strParams - Parameters for the class or the Method

CronTask

public CronTask()

Constructor of a task. We always call the constructor with no arguments, because the tasks are created dinamically (by Class.forName). You should call the method setParams inmediatly after creating a new task

Method Detail

setParams

public final void setParams(Crontab cront,
                            int iTaskID,
                            java.lang.String strClassName,
                            java.lang.String strMethodName,
                            java.lang.String[] strExtraInfo)

Selects the initial parameters for the task. As a task is created loaded dinamically from the class name, the default constructor called is the one with no arguments. You should call this method after creating the new instance of the task.

Parameters:

cront - The Crontab that creates and executes this task. It should be used to have access to other tasks, in order to wait for them or other tasks operations.

iTaskID - Identifier of the task

strExtraInfo - Extra information given to the task when created

getExtraInfo

protected final java.lang.String[] getExtraInfo()

Returns the aditional parameters given to the task in construction

Returns:

The aditional parameters given to the task in construction

getMethodName

protected final java.lang.String getMethodName()

Returns the Method Name given to the task in construction

Returns:

The aditional parameters given to the task in construction

runTask

public void runTask()

Runs this task. This method does the whole enchilada. This method decides wich method call in the given class

run

public final void run()

Runs this task

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread
