encodePrimitives

public static void encodePrimitives(IList<java.lang.Object> os,
                                    IDurableEncoding.Primitive encoding,
                                    DurableOutput out)

encodeSingleton

public static void encodeSingleton(java.lang.Object o,
                                   IDurableEncoding encoding,
                                   DurableOutput out)

encodeBlock

public static void encodeBlock(IList<java.lang.Object> os,
                               IDurableEncoding encoding,
                               DurableOutput out)

decodeCollection

public static IDurableCollection decodeCollection(BlockPrefix prefix,
                                                  IDurableCollection.Root root,
                                                  IDurableEncoding encoding,
                                                  DurableInput.Pool pool)

Decodes a singleton collection. This does NOT advance the input.

decodeBlock

public static IDurableEncoding.SkippableIterator decodeBlock(DurableInput in,
                                                             IDurableCollection.Root root,
                                                             IDurableEncoding encoding)

Decodes a block of encoded values, which may or may not be a singleton collection. This does NOT advance the input.

writeVLQ

public static void writeVLQ(long val,
                            DurableOutput out)

Writes a signed variable-length quantity.

readVLQ

public static long readVLQ(DurableInput in)

Reads a signed variable-length quantity.

writeUVLQ

public static void writeUVLQ(long val,
                             DurableOutput out)

Writes an unsigned variable-length quantity.

readUVLQ
