org.eclipse.jgit.util.io.LimitedInputStream
- All Implemented Interfaces:
Closeable
,AutoCloseable
Wraps a
InputStream
, 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
