Method Detail

encodeSingleValue

public static int encodeSingleValue(String mapName,
                                    String key,
                                    Object value,
                                    ByteBuffer buffer)

Encodes a single value as a complete binary map. Does nothing if the value is null. Returns the number of maps encoded - 0 or 1

encodeMap

public static int encodeMap(String mapName,
                            Map<String,?> map,
                            ByteBuffer buffer)

Encodes a map as binary. Does nothing if the value is null. Returns the number of maps encoded - 0 or 1

encodeMultiMap

public static <T> int encodeMultiMap(String mapName,
                                     Map<String,List<T>> map,
                                     ByteBuffer buffer)

Encodes a multi-map as binary. Does nothing if the value is null. Returns the number of maps encoded - 0 or 1
