org.jets3t.service.io.RepeatableInputStream
public class RepeatableInputStream
A repeatable input stream wrapper for any input stream. This input stream relies on buffered data to repeat, and can therefore only be repeated when less data has been read than this buffer can hold.
Note: Always use a RepeatableFileInputStream
instead of this class if you are
sourcing data from a file, as the file-based repeatable input stream can be repeated without
any limitations.
This class uses properties obtained through Jets3tProperties
. For more information on
these properties please refer to

public RepeatableInputStream(java.io.InputStream inputStream, int bufferSize)
inputStream
- an input stream to wrap. The data read from the wrapped input stream is buffered as it is
read, up to the buffer limit specified.bufferSize
- the number of bytes buffered by this class.Method Detail |

in class java.io.InputStream
UnrecoverableIOException
- when the available buffer size has been exceeded, in which case the input stream data cannot
be repeated.
