Class SFSObject

All Implemented Interfaces:

ISFSObject

Direct Known Subclasses:

SFSObjectLite

public class SFSObject
extends java.lang.Object
implements ISFSObject

SFSObject and SFSArray represent a platform-neutral, high level objects that abstract the data transport between client and server. They are used to respectively represent data in form of a Map/Dictionary or List/Array and they can be nested and transport many different data types (from bytes to integers, doubles, strings and a lot more)

These two classes provide a fine-grained control over each data item sent over the network and provide high speed serialization using the default SFS2X binary protocol.

Let's consider this simple example: we need to send the data relative to a combat vehicle in a multiplayer game.

 ISFSObject sfso = new SFSObject();
 sfso.putByte("id", 10);
 sfso.putShort("health", 5000);
 sfso.putIntArray("pos", Arrays.asList(120,150));
 sfso.putUtfString("name", "Hurricane"); 
 

In the above code we can use a single Byte (signed 8-bit) to send any small integer value, a Short (signed 16-bit) for larger values and integers for any number that should be represented as regular 32-bit value.

The following is a list of type supported by the SFSObject class:

• null
• boolean
• byte
• short
• int
• long
• float
• double
• utf-string
• boolean array
• byte array
• short array
• int array
• long array
• float array
• double array
• utf-string array
• SFSObject
• SFSArray

NOTE: UTF-8/multi-byte strings are not supported in key names. In other words you should restrict key names to standard ASCII characters.

It is also recommended to keep key names very short to save bandwidth. Strings values, instead, are handled via UTF-8 encoding, to support all languages and character sets. SFSObjects and SFSArrays can be nested to create complex data structures.

Limitations: UTF Strings length is expressed using a signed short integer which means that a string can be up to 32768 characters. (Sending a larger text can be done via set/getText methods) The same applies to all the array types whose length is encoded in the same way, thus limiting the max length of an array to 32768 elements.

NOTE: SFSObject is not thread safe.

public SFSObject()

Method Detail

newFromObject

public static SFSObject newFromObject(java.lang.Object o)

Converts any POJO (Plain Old Java Object) into an SFSObject providing a number of conventions and supported data types.

Supported types:

• null
• boolean, Boolean
• byte, Byte
• short, Short
• int, Integer
• long, Long
• float, Float
• double, Double
• String
• Collection
• Map
• Array types
• Nested POJOs

Other rules:

• Private fields are accessed from regular Java getters/setters, if they don't exist fields are ignored
• Public fields are accessed directly
• Static fields are ignored
• Transient fields are ignored

Conventions: When de-serialized on the other end the system will look for a Class with the same fully qualified name and will attempt to instantiate it and populate with the received data via reflection.

NOTE: complex objects might take up a significantly large amount of bytes compared to regular SFSObjects. If message size is a critical element and Class serialization seem to create too large packets we recommend to add a toSFSObject() and fromSFSObject() methods on your classes to generate smaller representations of the data you need to transfer.
Also, if possible, try to export only the fields that are strictly necessary and using the most suitable data type (e.g a byte or short for small numbers, etc...)
