Examples of org.apache.tika.io.CloseShieldInputStream

org.apache.tika.io.CloseShieldInputStream
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 Apache Tika 0.4, copied from Commons IO 1.4
