Interface SharedInputStream
public interface SharedInputStream
An InputStream backed by data that can be shared by multiple readers.
The users of such an InputStream can determine the current position in
the InputStream, and create new InputStreams representing a subset of
the data in the original InputStream.
The new InputStream will access the same underlying data as the original,
without copying the data in it.
long | getPosition() - Returns the current position in the InputStream as an offset from the
beginning of the InputStream.
|
InputStream | newStream(long start, long end) - Returns a new InputStream representing a subset of the data from this
InputStream, from
start (inclusive) up to
end (exclusive).

getPosition
public long getPosition()
Returns the current position in the InputStream as an offset from the
beginning of the InputStream.
newStream
public InputStream newStream(long start,
long end)
Returns a new InputStream representing a subset of the data from this
InputStream, from start
(inclusive) up to
end
(exclusive). start
must be non-negative.
If end
is -1, the new stream ends at the same place
as this stream. The returned InputStream will also implement the
SharedInputStream interface.
start
- the start positionend
- the end position + 1
