Class CloseOnceReader<T extends Reader>

java.lang.Object
  java.io.Reader
      java.io.FilterReader
          com.gc.iotools.stream.reader.CloseOnceReader<T>

Type Parameters:

T - Type of the Reader passed in the constructor.

All Implemented Interfaces:

Closeable, Readable

public class CloseOnceReader<T extends Reader>
extends FilterReader

A CloseOnceReader wraps some other Reader, which it uses as its basic source of data. The class CloseOnceReader 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 Reader that don't allow close() to be called multiple times.

Since:

1.2.7
