Class MarkShieldInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    public class MarkShieldInputStream
extends ProxyInputStream
    This is an alternative to ByteArrayInputStream which removes the synchronization overhead for non-concurrent access; as such this class is not thread-safe. Proxy stream that prevents the underlying input stream from being marked/reset.

    This class is typically used in cases where an input stream that supports marking needs to be passed to a component that wants to explicitly mark the stream, but it it is not desirable to allow marking of the stream.

    Since:
    2.8.0
