Closeable,AutoCloseable
public class FilterInputStream2 extends InputStream
AFilterInputStream2contains anotherInputStream, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.Note: unlike
FilterInputStreamthis class delegates every method by default. This means to transformreadcalls, you need to override multiple methods. On the other hand, it is less trappy: a simple implementation that just overridesclosewill not force bytes to be read one-at-a-time.
