Class JobManager.ThrottleJobItem

java.lang.Object
  org.apache.manifoldcf.crawler.jobs.JobManager.ThrottleJobItem

Enclosing class:

JobManager

protected static class JobManager.ThrottleJobItem
extends java.lang.Object

This class represents the information stored PER JOB in the throttling structure. In this structure, "remaining" counts are kept for each bin. When the bin becomes empty, then no more documents that would map to that bin will be returned, for this query. The way in which the maximum count per bin is determined is not part of this class.

Field Summary

protected java.util.HashMap	binCounts This is a map of the bins and their current counts.
protected java.util.ArrayList	throttleLimits These are the bin limits.

Constructor Summary

JobManager.ThrottleJobItem()
Constructor.

Method Summary

void	addLimit(java.lang.String regexp, int maxCount) Add a bin limit.
void	decrement(java.lang.String binName) Decrement specified bin.
JobManager.ThrottleJobItem	duplicate() Create a duplicate of this item.
protected int	findMaxCount(java.lang.String binName) Given a bin name, find the max value for it using the regexps that are in place.
boolean	isEmpty(java.lang.String binName) Check if the specified bin is empty.

throttleLimits

protected java.util.ArrayList throttleLimits

These are the bin limits. This is an array of ThrottleLimitSpec objects.

public JobManager.ThrottleJobItem()

Constructor.

addLimit

public void addLimit(java.lang.String regexp,
                     int maxCount)

Add a bin limit.

Parameters:

maxCount - is the maximum number of fetches allowed for that bin.

duplicate

public JobManager.ThrottleJobItem duplicate()

Create a duplicate of this item.

Returns:

the duplicate.

isEmpty

public boolean isEmpty(java.lang.String binName)

Check if the specified bin is empty.

Parameters:

binName - is the bin name.

Returns:

true if empty.

decrement

public void decrement(java.lang.String binName)

Decrement specified bin.

Parameters:

binName - is the bin name.

findMaxCount

protected int findMaxCount(java.lang.String binName)

Given a bin name, find the max value for it using the regexps that are in place.

Parameters:

binName - is the bin name.

Returns:

the max count for that bin, or -1 if infinite.
