org.apache.tools.ant.taskdefs.condition.ConditionBase
   org.apache.tools.ant.taskdefs.WaitFor

WaitFor
public class WaitFor extends ConditionBase (Code)
Wait for an external event to occur. Wait for an external process to start or to complete some task. This is useful with the parallel task to synchronize the execution of tests with server startup. The following attributes can be specified on a waitfor task:
  • maxwait - maximum length of time to wait before giving up
  • maxwaitunit - The unit to be used to interpret maxwait attribute
  • checkevery - amount of time to sleep between each check
  • checkeveryunit - The unit to be used to interpret checkevery attribute
  • timeoutproperty - name of a property to set if maxwait has been exceeded.
The maxwaitunit and checkeveryunit are allowed to have the following values: millisecond, second, minute, hour, day and week. The default is millisecond. For programmatic use/subclassing, there are two methods that may be overrridden, processSuccess and processTimeout
since:
   Ant 1.5

Inner Class :public static class Unit extends EnumeratedAttribute


Constructor Summary
public  WaitFor()
     Constructor, names this task "waitfor".

Method Summary
public  voidexecute()
     Check repeatedly for the specified conditions until they become true or the timeout expires.
protected  voidprocessSuccess()
     Actions to be taken on a successful waitfor. This is an override point.
protected  voidprocessTimeout()
     Actions to be taken on an unsuccessful wait. This is an override point.
public  voidsetCheckEvery(long time)
    
public  voidsetCheckEveryUnit(Unit unit)
    
public  voidsetMaxWait(long time)
     Set the maximum length of time to wait.
public  voidsetMaxWaitUnit(Unit unit)
    
public  voidsetTimeoutProperty(String p)
     Name the property to set after a timeout.


Constructor Detail
WaitFor
public WaitFor()(Code)
Constructor, names this task "waitfor".




Method Detail
execute
public void execute() throws BuildException(Code)
Check repeatedly for the specified conditions until they become true or the timeout expires.
throws:
  BuildException - on error



processSuccess
protected void processSuccess()(Code)
Actions to be taken on a successful waitfor. This is an override point. The base implementation does nothing.
since:
   Ant1.7



processTimeout
protected void processTimeout()(Code)
Actions to be taken on an unsuccessful wait. This is an override point. It is where the timeout processing takes place. The base implementation sets the timeoutproperty if there was a timeout and the property was defined.
since:
   Ant1.7



setCheckEvery
public void setCheckEvery(long time)(Code)
Set the time between each check
Parameters:
  time - a long value



setCheckEveryUnit
public void setCheckEveryUnit(Unit unit)(Code)
Set the check every time unit
Parameters:
  unit - an enumerated Unit value



setMaxWait
public void setMaxWait(long time)(Code)
Set the maximum length of time to wait.
Parameters:
  time - a long value



setMaxWaitUnit
public void setMaxWaitUnit(Unit unit)(Code)
Set the max wait time unit
Parameters:
  unit - an enumerated Unit value



setTimeoutProperty
public void setTimeoutProperty(String p)(Code)
Name the property to set after a timeout.
Parameters:
  p - the property name
