Class AutoCloseableContentLengthVerifyingInputStream

java.lang.Object

All Implemented Interfaces:

Closeable, AutoCloseable

public class AutoCloseableContentLengthVerifyingInputStream
extends ContentLengthVerifyingInputStream

A wrapper over an InputStream whose length is known, which verifies that the length of the wrapped stream matches its known length and auto-closes the stream once the content length bytes of the stream have been read. This auto-close feature has been added to release the connection from the Apache connection pool which can otherwise lead to indefinite hangs

NOTE: This implementation of auto closesable content length verification does not support InputStream.reset() and throws an IOException when reset is called
