Usage

Encoding Example

ByteArrayOutputStream baos = new ByteArrayOutputStream();
CborEncoder encoder = new CborEncoder(baos);
encoder.encode(new CborBuilder()
    .add("text")                // add string
    .add(1234)                  // add integer
    .add(new byte[] { 0x10 })   // add byte array
    .addArray()                 // add array
        .add(1)
        .add("text")
        .end()
    .build());
byte[] encodedBytes = baos.toByteArray();

Decoding Example

ByteArrayInputStream bais = new ByteArrayInputStream(encodedBytes);
CborDecoder decoder = new CborDecoder(bais);
List<DataItem> dataItems = decoder.decode();
for(DataItem dataItem : dataItems) {
    // process data item
}

Streaming Decoding Example

ByteArrayInputStream bais = new ByteArrayInputStream(encodedBytes);
CborDecoder decoder = new CborDecoder(bais);
decoder.decode(new DataItemListener() {

    @Override
    public void onDataItem(DataItem dataItem) {
        // process data item
    }

});
