Serialisation – Arma Reforger

This page talks about SCR_JsonSaveContext/SCR_JsonLoadContext and SCR_BinSaveContext/SCR_BinLoadContext.

JSON

Serialisation

SCR_JsonSaveContext context = new SCR_JsonSaveContext(); string stringValue = "data"; int integerValue = 123; context.WriteValue("key1", stringValue); context.WriteValue("key2", integerValue); // process saved data (export, send, save...), in this case data are exported as json string dataString = context.ExportToString();

Deserialisation

SCR_JsonLoadContext context = new SCR_JsonLoadContext(); context.ImportFromString(dataString); string stringValue; int integerValue; // order does not matter for JSON as it uses key names context.ReadValue("key2", integerValue); context.ReadValue("key1", stringValue);

Binary

Serialisation

SCR_BinSaveContext context = new SCR_BinSaveContext(); string stringValue = "data"; int integerValue = 123; context.WriteValue("key1", stringValue); context.WriteValue("key2", integerValue); // process saved data (export, send, save...), in this case data are saved to "file.bin" context.SaveToFile("file.bin");

Deserialisation

SCR_BinLoadContext context = new SCR_BinLoadContext(); context.LoadFromFile("file.bin"); string stringValue; int integerValue; // order matters for Binary serialisation, as Binary ignores names context.ReadValue("key1", stringValue); context.ReadValue("key2", integerValue);

Object Serialisation

Simple

The following class set to serialise will serialise all its properties.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable; protected float m_fVariable = 33.3; };

NonSerialized

Adding the NonSerialized() decorator to a field will make the serialisation ignore it.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable = "Hello there"; [NonSerialized()] protected float m_fVariable = 33.3; };

Advanced

The following methods allow to define a custom serialisation per class. This is useful to avoid saving lengthy yet useless information for loading as well as load values in a certain order.

ⓘ

The NonSerialized decorator is only useful with the simple object serialisation - SerializationSave/SerializationLoad will ignore it.

SerializationSave

If an object has the SerializationSave method defined, the SaveContext will use it and not process object's properties automatically at all.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable = "Hello there"; protected float m_fVariable = 33.3; bool SerializationSave(BaseSerializationSaveContext context) { if (!context.IsValid()) return false; context.WriteValue("theString", m_sVariable); context.WriteValue("integer", m_iVariable); context.WriteValue("floatingpoint", m_fVariable); return true; } };

SerializationLoad

If an object has the SerializationLoad method defined, the SaveContext will use it and not process object's properties automatically at all.

class MyClass : Managed { protected int m_iVariable = 42; protected string m_sVariable = "Hello there"; protected float m_fVariable = 33.3; bool SerializationLoad(BaseSerializationLoadContext context) { if (!context.IsValid()) return false; context.ReadValue("theString", m_sVariable); context.ReadValue("integer", m_iVariable); context.ReadValue("floatingpoint", m_fVariable); return true; } };
