Happy new year!

Thanks. Same to you.

It seems this can be a struct, then you don't need the accessors.

[jrummell, 2015/01/05 22:17:59]

Done.

+ public:
+  enum KeyStatus {
+    USABLE = 0,
+    INTERNAL_ERROR = 1,
+    EXPIRED = 2,
+    OUTPUT_NOT_ALLOWED = 3
+  };
+
+  CdmKeyInformation(const std::string& key_id,
+                    KeyStatus status,
+                    uint32 system_code);
+  CdmKeyInformation(const uint8* key_id_data,
+                    uint32 key_id_length,
+                    KeyStatus status,
+                    uint32 system_code);

[xhwang, 2015/01/02 21:55:07]

See comment below, you don't need a version of ctor that takes uint8*/uint32.
Then you might just have a ctor that takes std::vector<uint8> directly.

[jrummell, 2015/01/05 22:17:59]

Simplified to a struct.

+  virtual ~CdmKeyInformation();

[xhwang, 2015/01/02 21:55:07]

It seems this is not a base class - no need to use "virtual" here.

[jrummell, 2015/01/05 22:17:59]

Done.

+
+  const std::vector<uint8>& KeyId() const { return key_id_; }
+  KeyStatus Status() const { return status_; }
+  uint32 SystemCode() const { return system_code_; }

[xhwang, 2015/01/02 21:55:07]

For accessor, use key_id()/status()/system_code().

[jrummell, 2015/01/05 22:17:59]

Not needed now that this is a struct.

+
+ private:
+  std::vector<uint8> key_id_;
+  KeyStatus status_;
+  uint32 system_code_;

[xhwang, 2015/01/02 21:55:07]

If you have only one ctor that takes std::vector<uint8>, you can make all these
three members const.

[jrummell, 2015/01/05 22:17:59]

Now a struct.
