在api调用中将对象保存到Android Realm DB中

Question

我想将从API调用接收的对象存储到领域db。

示例Obj：

[
        {
            "obj_type": "ClassSession",
            "_id": "0341bd22-1182-4db3-a667-c8647012741e",
            "version": "b2",
            "createdOn": "2017-04-01 12:57:39 +0530",
            "stage": "SCHEDULED",
            "type": "Class Session",
            "scheduled_at": "2017-04-01 12:58:39 +0530"
        },
        {
            "obj_type": "Assignment",
            "_id": "CmsRsrc2",
            "version": "b3",
            "name": "Homework",
            "type": "HOMEWORK",
            "parent": {
                "type": "topic",
                "id": "parent_id1"
            },
            "resource_id": "CmsRsrc2",
            "assignmentProperty": {}
        },
        {
            "obj_type": "Task",
            "_id": "21b72bc0eb3e6d4a1c2bb332593ee19bbc527c92c9249585bed785fc6339e155",
            "version": "b0",
            "source": {
                "type": "T_PROBLEM",
                "id": "problem_id1_1"
            },
            "correctAnswer": 1
        },
        {
            "obj_type": "TaskRecord",
            "_id": "ff0748aea74431786a20629ad57676fc84eaa7396b153206540ee9eac1d9bfc8",
            "assignmentId": "CmsRsrc2",
            "version": "b0/",
            "status": "ACTIVE",
            "marking_scheme": {},
            "sequence": 1
        }
    ]

我有每个obj_type的realm类但我不知道如何从api接收obj，因为从api收到的响应obj不属于任何领域类。

所以我正在寻找一种方法来接收api发送的obj并将其保存到相应的realm类。
