Returns true if the computer is accepting tasks. Needed to allow retention strategies programmatic suspension of task scheduling that in preparation for going offline. Called by Computer.isAcceptingTasks()

Overrides:

isAcceptingTasks in class RetentionStrategy<SlaveComputer>

Parameters:

c - the computer.

Returns:

true if the computer is accepting tasks

check

public long check(SlaveComputer c)

Description copied from class: RetentionStrategy

This method will be called periodically to allow this strategy to decide what to do with its owning agent.

Specified by:

check in class RetentionStrategy<SlaveComputer>

Parameters:

c - Computer for which this strategy is assigned. This computer may be online or offline. This object also exposes a bunch of properties that the callee can use to decide what action to take.
