Member Function Documentation

addRequest()

void RequestManager::addRequest

(

Request *

request

)

Add the specified request to the RequestMap.

This routine should only be called if shouldRequestBeAdded returns 1.

Parameters

request

pointer to the request to be added to the map

disableRequestProcessing()

void RequestManager::disableRequestProcessing

(

int64_t

handle

)

Mark the Request Handle, so that the Request won't be applied.

This method is used to Handle Untune Requests, as soon as an Untune Request for Handle h1 is received, we call this Rountine for h1, so that it doesn't get serviced in case it has not been inserted into the Coco Table yet. Note: If the Request was already inserted, then it will be untuned as and when the Untune Request gets serviced by the RequestQueue.

Parameters

handle

Request Identifier, for which processing needs to be disabled.

getActiveReqeustsCount()

int64_t RequestManager::getActiveReqeustsCount

(

)

Get the current Global Active Requests Count.

Returns

: int64_t

getRequestFromMap()

Request * RequestManager::getRequestFromMap

(

int64_t

handle

)

Retrieve the Request with the given Handle.

Parameters

handle

Request Handle

Returns

Request*:

• Pointer to the request with the specified index.

moveToPendingList()

void RequestManager::moveToPendingList

(

)

Handles Device Mode transition from RESUME to SUSPEND.

As part of this routine, the CocoTable will be drained out, i.e. all active Requests will be untuned, and the Resources restored to their original values. Requests which are not eligible for background processing will be removed from the Active List and put into the Pending List, so that they get processed again when the Device transitions back to the RESUME mode.
