JakartaPostOperation

public class StreamedUploadOperation
extends AbstractPostOperation

Performs a streamed modification of the content. Each File body encountered will result in a session save operation, to cause the underlying Resource implementation to stream content from the request to the target. This implements PostOperation but does not touch the normal Sling Request processing which is not streamed. The map of available fields is built up as the request is streamed. It is advisable to submit the request with all the form fields at the start of the request (normally based on DOM order) to ensure they are available before the streamed bodies are processed. The implementation does not implement the full Sling protocol aiming to keep it simple, and just deal with a streaming upload operation. The implementation binds to the Sling Resource API rather than JCR to keep it independent of the type of persistence.
