public abstract class LimitedInputStream extends java.io.FilterInputStream
Wraps aInputStream
, limiting the number of bytes which can be read. This class was copied and modifed from the Google Guava 16.0. Differently from the original Guava code, when a caller tries to read from this stream past the given limit and the wrapped stream hasn't yet reached its EOF this class will call the limitExceeded method instead of returning EOF.- Since:
- 3.3

limitExceeded
protected abstract void limitExceeded() throws java.io.IOException
Called when trying to read past the givenlimit
and the wrapped InputStreamFilterInputStream.in
hasn't yet reached its EOF- Throws:
java.io.IOException
- subclasses can throw anIOException
when the limit is exceeded. The throws java.io.IOException will be forwarded back to the caller of the read method which read the stream past the limit.
