Class ExecutorPluginContext

java.lang.Object
  org.gcube.common.core.plugins.GCUBEPluginContext
      org.gcube.vremanagement.executor.plugin.ExecutorPluginContext

public abstract class ExecutorPluginContext
extends org.gcube.common.core.plugins.GCUBEPluginContext

Extends GCUBEPluginContext to provide the service with information about its plugin.

Subclasses must indicate the class of an executable ExecutorTask (cf. getTaskClass()).
They may also provide examples of the any inputs the task may take and any output the task may produce (cf. addSampleInput(DescriptiveProperty), addSampleOutput(DescriptiveProperty...)).
Finally, they may also indicate the time after which task executions that are completed or have failed can be forgotten (cf. getTimeToLive()).
