- All Implemented Interfaces:
ByteProvider
,java.io.Closeable
,java.lang.AutoCloseable
public class InputStreamByteProvider extends java.lang.Object implements ByteProvider
AByteProvider
implementation that wraps anInputStream
, allowing data to be read, as long as there are no operations that request data from a previous offset.In other words, this
ByteProvider
can only be used to read data at ever increasing offsets.
