Abstract
Abstract A computer method and system for invoking a function member of an object that is exposed to a client computer program by a source computer program are provided. In a preferred embodiment, the source computer program instantiates the object which has a dispatching interface. The dispatching interface has an invoking function member for receiving a name of a function member and arguments for the function member. When a client computer program wishes to invoke the function member, the client computer program invokes the invoking function member of the dispatching interface passing the name of the function member and arguments for the function member. The invoking function member invokes the function member with the passed name passing the arguments. When the function member returns, the invoking function member returns to the client computer program.
