## Class IdentityInputStream

- java.lang.Object
- - 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
