Detailed Description

Interface for getting asynchronously computed data into Lua.

The class is designed to be a general interface to some process which is computing values. The getObject function returns the "current" value and some control information. The subclass is responsible for all aspects of the asynchronous operation: Starting/stopping, data synchronization, and serialization/deserialization. The Lua framework will hold on to this object as a shared pointer.

Member Function Documentation

virtual luabind::object DtLuaAsyncJob::getObject ( lua_State *  L, int &  index, std::string &  message  )

pure virtual

Retrieve current value.

Parameters

L	Lua state.
index	Index of returned value, returned in Lua as the second return value. Allows implementation to distinguish between different values computed over time.
message	Error message, returned in Lua as the third return value.

Returns

Computed value.

Implemented in DtLuaNavPointOfInterestJob, DtLuaNavRandomPointJob, DtLuaPathJob, and DtLuaNavJob.

void DtLuaAsyncJob::init ( void *  userData )

virtual

Called by framework with userData set to the DtSimManager.

Reimplemented from DtAsciiSerializable.
