=head1 Name
SPVM::Document::NativeAPI::ClassFile - Class File Native APIs
=head1 Description
The class file native APIs of L<SPVM> are the APIs to get and set class file information.
=head1 Usage
SPVM_API_CLASS_FILE* api_class_file = env->api->class_file;
void* class_file = env->api->compiler->get_class_file(compiler, "MyClass");
const char* class_name = api_class_file->get_class_name(compiler, class_file);

=head2 get_class_name
const char* (*get_class_name)(void* compiler, void* class_file);
Returns the class name of the class file I<class_file>.
=head2 get_file
const char* (*get_file)(void* compiler, void* class_file);
Returns the file path for display. This is a field of the class file I<class_file>.
=head2 set_file
void (*set_file)(void* compiler, void* class_file, const char* file);
Copies I<file> and sets it to the file path for display. This is a field of the class file I<class_file>.
=head2 get_dir
const char* (*get_dir)(void* compiler, void* class_file);
Returns the directory where the class is loaded. This is a field of the class file I<class_file>.
=head2 set_dir
void (*set_dir)(void* compiler, void* class_file, const char* dir);
Copies the directory path I<dir>, and sets it to the directory where the class is loaded. This is a field of the class file I<class_file>.
=head2 get_rel_file
const char* (*get_rel_file)(void* compiler, void* class_file);
Returns the relative file path of the class file I<class_file>.
=head2 set_rel_file
void (*set_rel_file)(void* compiler, void* class_file, const char* rel_file);
Copies I<rel_file> and sets it to the relative file path of the class file I<class_file>.
=head2 get_content
const char* (*get_content)(void* compiler, void* class_file);
Returns the content of the class file I<class_file>.
=head2 set_content
void (*set_content)(void* compiler, void* class_file, const char* content);
Copies the content I<content> and sets it to the content of the class file I<class_file>.
=head2 get_content_length
int32_t (*get_content_length)(void* compiler, void* class_file);
Returns the length of the content of the class file I<class_file>.
=head2 set_content_length
void (*set_content_length)(void* compiler, void* class_file, int32_t content_length);
Sets I<content_length> to the length of the content of the class file I<class_file>.
