All Implemented Interfaces:

Closeable, AutoCloseable

Direct Known Subclasses:

AutoCloseableContentLengthVerifyingInputStream

public class ContentLengthVerifyingInputStream
extends InputStream

A wrapper over an InputStream whose length is known, which verifies that the length of the wrapped stream matches its known length.

NOTE: This implementation of content length verification does not support InputStream.reset() and the verification is disabled upon invocation of InputStream.reset().
