JPDA Architecture Research 15-agent access VMS using environment pointers (field access)

Introduced:

We've explored how agents can access VMS using environment pointers (object-level operations), and now we're talking about letting agents access the fields of the class using an environment pointer.

Category 10: Field access

A.getfieldname. Getting a field name for a class

Jvmtierrorgetfieldname (jvmtienv* env, Jclass Klass, Jfieldid field, char** name_ptr, char** signature_ptr, char** generic_ptr)

B.getfielddeclaringclass. Gets the class that declares the field

Jvmtierrorgetfielddeclaringclass (jvmtienv* env, Jclass Klass, Jfieldid field, Jclass* Dec LARING_CLASS_PTR)

C.getfieldmodifiers. Gets the access modifier for a field of a class

Jvmtierrorgetfieldmodifiers (jvmtienv* env, Jclass Klass, Jfieldid field, jint* Modifiers_ ptr

D.isfieldsynthetic. Determine if a field in a class is a fictional field

Jvmtierrorisfieldsynthetic (jvmtienv* env, Jclass Klass, Jfieldid field, jboolean* Is_synt HETIC_PTR)

The so-called imaginary fields are the fields generated by the compiler rather than directly defined in the source code.
