DownloadServlet.ContentSource (Payara Project 6.2022.1.Alpha3 API)

All Known Implementing Classes:

ClientStubsContentSource, LBConfigContentSource, LogFilesContentSource, LogViewerContentSource

Enclosing class:

DownloadServlet
```
public static interface DownloadServlet.ContentSource
```
Implement this interface to provide an Object that is capable of providing data to DownloadServlet. ContentSource implementations must be thread safe. The DownloadServlet will reuse the same instance when 2 requests are made to the same ContentSource type. Instance variables, therefore, should not be used; you may use the context to store local information.
