Hi @zhangping Thanks for raising this!

According to the Mermaid documentation, the * symbol is used as a classifier to indicate an abstract method, and it can be placed after the () or the return type:

Abstract e.g.:

someAbstractMethod()*
or
someAbstractMethod() int*

**Suggested Direction
If support for pointer types is desired, this issue would be better categorized as an enhancement.

**Suggested improvements:

Add syntax-level support for pointer types (e.g., int*, char*, MyClass*)

Improve the parser to distinguish between:

int* (return type with pointer)

int* * (return type + abstract classifier)

Let me know if you'd like help implementing this or discussing possible solutions. Happy to contribute!
