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

    public class LazySequenceInputStream
    extends java.io.InputStream
    A SequenceInputStream-like implementation with lazy input stream iterator. An input stream in the iterator is initialized and consumed only when the previous input stream is fully consumed.
