## Class CloseShieldInputStream

- java.lang.Object
- - java.io.InputStream
  - - java.io.FilterInputStream
    - - org.apache.commons.io.input.ProxyInputStream

- All Implemented Interfaces:
    Closeable, AutoCloseable

      public class CloseShieldInputStream
      extends ProxyInputStream

  Proxy stream that prevents the underlying input stream from being closed.

  This class is typically used in cases where an input stream needs to be passed to a component that wants to explicitly close the stream even if more input would still be available to other components.

  Since:
    1.4

    Constructor and Description
    `CloseShieldInputStream(InputStream inputStream)` Deprecated. Using this constructor prevents IDEs from warning if the underlying input stream is never closed. Use `wrap(InputStream)` instead.

    `void` | `close()` Replaces the underlying input stream with a `ClosedInputStream` sentinel.

    - #### CloseShieldInputStream

          @Deprecated
          public CloseShieldInputStream(InputStream inputStream)

      Deprecated. Using this constructor prevents IDEs from warning if the underlying input stream is never closed. Use `wrap(InputStream)` instead.
      Creates a proxy that shields the given input stream from being closed.
      Parameters:
        `inputStream` - underlying input stream

  - ### Method Detail

    - #### wrap

          public static CloseShieldInputStream wrap(InputStream inputStream)

      Creates a proxy that shields the given input stream from being closed.
      Parameters:
        `inputStream` - the input stream to wrap
      Returns:
        the created proxy
      Since:
        2.9.0

    - #### close

          public void close()

      Replaces the underlying input stream with a `ClosedInputStream` sentinel. The original input stream will remain open, but this proxy will appear closed.
