Do we need this, or could we just pass in a vector of length 1?

[lanwei, 2016/10/30 23:23:13]

Because most of the cases that we will only have one action_params, so I delete
the constructor of std::vector<SyntheticPointerActionParams>. Is it ok?

[tdresser, 2016/10/31 14:22:57]

Acknowledged.

+  SyntheticPointerActionListParams(
+      std::vector<SyntheticPointerActionParams>& param_list);
+  SyntheticPointerActionListParams(
+      const SyntheticPointerActionListParams& other);

[tdresser, 2016/10/26 18:28:40]

Do we need to be able to copy these?

[lanwei, 2016/10/30 23:23:13]

Yes, because SyntheticGestureParams has it, all of its sub-classes have it

+  ~SyntheticPointerActionListParams() override;
+
+  GestureType GetGestureType() const override;
+
+  std::vector<SyntheticPointerActionParams> param_list;
+
+  static const SyntheticPointerActionListParams* Cast(
+      const SyntheticGestureParams* gesture_params);
+};
+
+}  // namespace content
+
+#endif  // CONTENT_COMMON_INPUT_SYNTHETIC_POINTER_ACTION_LIST_PARAMS_H_
