The RJCB-generated bridge code makes direct, interface-specific vtable calls.
RJCB 生成的桥代码可以进行直接的、针对特定接口的 vtable调用。
The performance of this sample and the pure vtable-based sample are exactly identical.
这个例子的性能和纯虚函数表例子是相同的。
For this reason, RJCB Bridges support only COM APIs that provide early-bound vtable interfaces.
出于这个原因，rjcb桥只支持那些提供前期绑定vtable接口的COMAPI。
It obtains the pointer to the vtable of the class from the first 4 bytes of the object's instance data.
它包含类的vtable表的指针，包含位置是在对象实例数据的前4字节里。
The RJCB code generator generates Java proxies for each vtable interface and coclass defined in the COM type library.
RJCB代码生成器为COM类型库中定义的每个vtable接口和 辅助类生成代理。
The memory image of an instance of a class has one pointer to the vtable of this class, stored in front of the actual data members of the object.
类的实例的内存快照里有一个vtable的指针，该指针位置在实际的成员变量前面。
Overhead in memory is very small: You basically have a 4- byte overhead per interface (the vtable pointers in the object's instance data) plus 4 bytes for the reference counter.
内存开销非常小：基本上每个接口需要额外4个字节（对象实例数据里虚函数表指针），加上引用计数的4个字节。
Code generated by a client's compiler can freely access all these tables through the vtable pointer, which is always located in the first 4 bytes of the memory image of the object.
客户端编译生成的代码能够自由存取vtable指针里的所有表，vtable始终在对象的内存映象的前4个字节里。
Code generated by a client's compiler can freely access all these tables through the vtable pointer, which is always located in the first 4 bytes of the memory image of the object.
