Package io.netty.handler.codec.http.multipart

Class DefaultHttpDataFactory

java.lang.Object

io.netty.handler.codec.http.multipart.DefaultHttpDataFactory

All Implemented Interfaces:

HttpDataFactory

public class DefaultHttpDataFactory
extends Object
implements HttpDataFactory

Default factory giving Attribute and FileUpload according to constructor.

According to the constructor, Attribute and FileUpload can be:

• MemoryAttribute, DiskAttribute or MixedAttribute
• MemoryFileUpload, DiskFileUpload or MixedFileUpload

A good example of releasing HttpData once all work is done is as follow:

   for (InterfaceHttpData httpData: decoder.getBodyHttpDatas()) {
     httpData.release();
     factory.removeHttpDataFromClean(request, httpData);
   }
   factory.cleanAllHttpData();
   decoder.destroy();
