Detailed Description

This class encapsulates a CursorableLinkedList<CollectorData>, which holds all monitor collector references together with their data that got harvested by a blobber. It allows calls to add(CollectorData) and remove(CollectorData) while iterating over the list of CollectorData objects using methods next() or hasNext().

The only added value compared to using the CursorableLinkedList directly is the synchronization of concurrent calls and the type casts (CursorableLinkedList does not support generics).

Member Function Documentation

CollectorListStatus alma.acs.monitoring.blobber.CollectorList.add

(

String

inCollectorName

)

Creates and adds a CollectorData object for the given collector ID.

See also:

add(CollectorData)

Referenced by alma.acs.monitoring.blobber.BlobberWorker.addCollector().

CollectorListStatus alma.acs.monitoring.blobber.CollectorList.add

(

CollectorData

inData

)

Parameters:

inData

The object that identifies a collector and holds its data.

Returns:

ADDED if the CollectorData object was added to this list, or KNOWN if it was already in the list.

CollectorListStatus alma.acs.monitoring.blobber.CollectorList.contains

(

CollectorData

inData

)

[protected]

This method is currently used only from contains(String). Make it public if it should be used from outside.

CollectorListStatus alma.acs.monitoring.blobber.CollectorList.contains

(

String

inCollectorName

)

Parameters:

inCollectorName

The ID of the collector for which we check the list.

Returns:

KNOWN if the given collector is already in this list, or UNKNOWN otherwise.

Referenced by alma.acs.monitoring.blobber.BlobberWorker.containsCollector().

boolean alma.acs.monitoring.blobber.CollectorList.hasNext

(

)

Returns:

true if a subsequent call to next() will return another CollectorData object from the current iteration; false otherwise.

Referenced by alma.acs.monitoring.blobber.BlobberWorker.run().

CollectorData alma.acs.monitoring.blobber.CollectorList.next

(

)

Returns:

The next CollectorData from the list.

Exceptions:

NoSuchElementException

if we are at the end of the list. Should have checked with hasNext(), and called resetIterator().

CollectorListStatus alma.acs.monitoring.blobber.CollectorList.remove

(

String

inCollectorName

)

Parameters:

inCollectorName

Returns:

REMOVED if the given collector was in this list and got removed, or UNKNOWN otherwise.

Referenced by alma.acs.monitoring.blobber.BlobberWorker.removeCollector().

synchronized CollectorListStatus alma.acs.monitoring.blobber.CollectorList.remove

(

CollectorData

inData

)

[protected]

This method is currently used only from remove(String). Make it public if it should be used from outside.

void alma.acs.monitoring.blobber.CollectorList.resetIterator

(

)

Referenced by alma.acs.monitoring.blobber.CollectorList.CollectorList(), and alma.acs.monitoring.blobber.BlobberWorker.run().

int alma.acs.monitoring.blobber.CollectorList.size

(

)

Returns:

The number of monitor collectors in this list.
