}

Here is the call graph for this function:

void nsIStreamListener::onDataAvailable ( in nsIRequest  aRequest,
in nsISupports  aContext,
in nsIInputStream  aInputStream,
in unsigned long  aOffset,
in unsigned long  aCount 
) [inherited]

Called when the next chunk of data (corresponding to the request) may be read without blocking the calling thread.

The onDataAvailable impl must read exactly |aCount| bytes of data before returning.

Parameters:
aRequestrequest corresponding to the source of the data
aContextuser defined context
aInputStreaminput stream containing the data chunk
aOffsetNumber of bytes that were sent in previous onDataAvailable calls for this request. In other words, the sum of all previous count parameters. If that number is greater than or equal to 2^32, this parameter will be PR_UINT32_MAX (2^32 - 1).
aCountnumber of bytes available in the stream

NOTE: The aInputStream parameter must implement readSegments.

An exception thrown from onDataAvailable has the side-effect of causing the request to be canceled.

void nsIRequestObserver::onStartRequest ( in nsIRequest  aRequest,
in nsISupports  aContext 
) [inherited]

Called to signify the beginning of an asynchronous request.

Parameters:
aRequestrequest being observed
aContextuser defined context

An exception thrown from onStartRequest has the side-effect of causing the request to be canceled.

Here is the caller graph for this function:

void nsIRequestObserver::onStopRequest ( in nsIRequest  aRequest,
in nsISupports  aContext,
in nsresult  aStatusCode 
) [inherited]

Called to signify the end of an asynchronous request.

This call is always preceded by a call to onStartRequest.

Parameters:
aRequestrequest being observed
aContextuser defined context
aStatusCodereason for stopping (NS_OK if completed successfully)

An exception thrown from onStopRequest is generally ignored.

Here is the caller graph for this function:
