Wrapping method, registration method, device, and rendering apparatus

A rendering apparatus, comprising:

• an execution engine, configured to send an initialization instruction for initializing a wrapper object to a virtual machine, wherein the initialization instruction is acquired by loading a target code through the execution engine, and to receive an execution code corresponding to the target code from the virtual machine;
• the virtual machine, configured to receive the initialization instruction from the execution engine;
• to send a registration instruction through a registration interface for registering the wrapper object to a registry component according to the initialization instruction, wherein the registration instruction comprises an identification of the wrapper object to be registered, in the target code;
• to acquire the execution code corresponding to the target code by a compilation, according to a mapping relation between a wrapper object and a native code of an operating system;
• and to send the execution code to the execution engine for execution;
• and
• the registry component, configured to receive the registration instruction from the virtual machine through the registration interface;
• and send a creation instruction to a wrapper module through a creation interface, to create a corresponding wrapper object in the wrapper module according to the identification of the wrapper object in the creation instruction.
