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.

Method Summary

Method Detail

getPosition

public long getPosition()

Returns the current position in the InputStream as an offset from the beginning of the InputStream.

newStream

public java.io.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.

Parameters:

start - the start position

end - the end position + 1
