Unity and codegeneration

While working on Unity plugin project I need to map JSON to the C# objects. For this task I used modification of the fastJSON library. But fastJSON use codegeneration for creating special methods for reading/writing object properties. It looks like:

if (fieldInfo.FieldType.IsValueType)
    il.Emit(OpCodes.Unbox_Any, fieldInfo.FieldType);
il.Emit(OpCodes.Stfld, fieldInfo);

This solution provide great performance, but make it impossible to use this library in the iOS environment. To fix this I add option to the JSON parameters class to use alternative approach for creating methods for reading/writing object properties. Approach is to use anonymous methods:

if (parameters.WithoutDynamicMethodsGeneration) 
	return (target, val) =>
		fieldInfo.SetValue(target, val);
		return target;

This fix implemented in commit e52135c
