Class LimitedInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    class LimitedInputStream
extends java.io.InputStream
    Implementation of the InputStream abstract class, which is used to restrict reading bytes from input stream i.e. if more bytes are read than the readingByteLimit, an ReadingByteLimitException exception will be thrown. Note that the readingByteLimit is not taken into account in the skip(long), available(), mark(int) and reset() methods.
