Class SizeLimitedInputStream

java.lang.Object

java.io.InputStream

com.atlassian.confluence.util.http.SizeLimitedInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class SizeLimitedInputStream
extends InputStream

This is a wrapper around an InputStream that limits the amount of data that can be returned. This allows admins to set maximum download sizes for Confluence retrieved content, so that people can't, say, point the RSS macro at an ISO file and cause the system to collapse painfully.

If you try to retrieve more than the maximum allowed size, the read() methods will fail with an IOException
