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.- Version:
