Class KeepAliveInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable

    public class KeepAliveInputStream
    extends java.io.FilterInputStream
    Class that can be used to wrap System.in without getting anxious about any client closing the stream.

    In code-language it means that it is not necessary to do:

     if (out != System.in) {
       in.close();
     }
     
    Since:
    Ant 1.6
