Constructs a reader that decodes bytes from the given channel using the given decoder.

The resulting stream will contain an internal input buffer of at least minBufferCap bytes. The stream's read methods will, as needed, fill the buffer by reading bytes from the underlying channel; if the channel is in non-blocking mode when bytes are to be read then an IllegalBlockingModeException will be thrown. The resulting stream will not otherwise be buffered, and it will not support the mark or reset methods. Closing the stream will in turn cause the channel to be closed.

Parameters:

ch     The channel from which bytes will be read

dec     The charset decoder to be used

minBufferCap     The minimum capacity of the internal byte buffer, or -1 if an implementation-dependent default capacity is to be used

Returns: A new reader

`ch`		The channel from which bytes will be read
`dec`		The charset decoder to be used
`minBufferCap`		The minimum capacity of the internal byte buffer, or `-1` if an implementation-dependent default capacity is to be used
