Syntaxvar retval = msStreamReader.readAsBlob(stream, size);
- stream [in]
Object that holds the MSStream object to read.
- size [in, optional]
Type: signed long long
String that specifies the maximum size of the object to read.
The Blob that was created from the specified stream.
The readAsBlob method is used by msStreamReader to create a Blob object from an MSStream. When the read begins, the readyState property is set to the
LOADING state on MSStreamReader and the onloadstart event is fired. Progress for the read is monitored by the onprogress event. When the read completes, the onloadend event fires and readyState is set to
DONE and MSStreamReader.result returns the new Blob object.
A read operation can be interrupted if an error occurs or the abort method is run. If an error occurs, the onerror event fires. This stops the read operation, fires the onloadendevent, sets the readyState to
DONE, and passes the error using the error property.
For a code example, see MSStreamReader.
