java.io.InputStream

org.apache.hc.core5.http.impl.io.IdentityInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class IdentityInputStream
extends InputStream

Input stream that reads data without any transformation. The end of the content entity is demarcated by closing the underlying connection (EOF condition). Entities transferred using this input stream can be of unlimited length.

Note that this class NEVER closes the underlying stream, even when close() gets called. Instead, the stream will be marked as closed and no further reading will be permitted.

Since:

4.0
