Constructor Detail

Zipper

public Zipper(BitWriter bitwriter)

Create a new encoder. It may be used for an entire session or subsession.

Parameters:

bitwriter - The BitWriter this encoder will output to. Don't forget to flush.

Method Detail

flush

public void flush()
           throws JSONException

Finish the final byte and flush the bitwriter. This does the same thing as pad(8).

Throws:

JSONException

pad

public void pad(int width)
         throws JSONException

Pad the output to fill an allotment of bits.

Parameters:

width - The size of the bit allotment. A value of 8 will complete and flush the current byte. If you don't pad, then some of the last bits might not be sent to the Output Stream.

Throws:

JSONException

encode

public void encode(JSONObject jsonobject)
            throws JSONException

Encode a JSONObject.

Parameters:

jsonobject - The JSONObject.

Throws:

JSONException

encode

public void encode(JSONArray jsonarray)
            throws JSONException

Encode a JSONArray.

Parameters:

jsonarray - The JSONArray.

Throws:

JSONException
