Class CloseOnceInputStream<T>

java.lang.Object
  java.io.InputStream
      java.io.FilterInputStream
          com.gc.iotools.stream.is.CloseOnceInputStream<T>

All Implemented Interfaces:

Closeable

public class CloseOnceInputStream<T>
extends FilterInputStream

A CloseOnceInputStream contains some other input stream, which it uses as its basic source of data. The class CloseOnceInputStream pass all requests to the contained input stream, except the close() method that is passed only one time to the underlying stream.

Multiple invocation of the close() method will result in only one invocation of the same method on the underlying stream. This is useful with some buggy InputStream that don't allow close() to be called multiple times.

Since:

1.2.6
