class LimitedInputStream extends java.io.InputStream
Implementation of theInputStream
abstract class, which is used to restrict reading bytes from input stream i.e. if more bytes are read than the readingByteLimit, anReadingByteLimitException
exception will be thrown. Note that the readingByteLimit is not taken into account in theskip(long)
,available()
,mark(int)
andreset()
methods.
