成员函数说明

mainloop()

virtual void mainloop ( )

pure virtual

Called once through each main loop iteration to handle updates. Remote object mainloop() should call client_mainloop() and then call d_connection->mainloop(). Server object mainloop() should service the device and then call server_mainloop(), but should not normally call d_connection->mainloop().

实现了 vrpn_BaseClass.

在 vrpn_DreamCheeky_Drum_Kit 内被实现.

on_data_received()

void on_data_received ( size_t bytes, vrpn_uint8 * buffer )

protectedvirtual

Derived class reimplements this callback. It is called whenever a read returns some data.

WARNING! The data returned by this function differs when the device sends multiple report types and when it only has one. When it can have more than one, the report type is sent as the first byte. When it only has one, the report type is NOT included. This is the behavior of the HIDAPI library we are using. It is surprising to me, but that's how it behaves.

实现了 vrpn_HidInterface.

register_types()

int register_types ( void )

inlineprotectedvirtual

Register the types of messages this device sends/receives. Return 0 on success, -1 on fail.

实现了 vrpn_BaseClass.
