A visitor to visit a Java class.

The methods of this trait must be called in the following order: visit -> visit_source -> visit_module -> (visit_field | visit_method)* -> visit_end.

Provided Methods

fn visit( &mut self, _major: u16, _minor: u16, _access_flags: u16, _name: &str, _super_name: Option<&str>, _interfaces: &[String], )

Visits the header of the class.

Arguments

• major - The major version number of the class file.
• minor - The minor version number of the class file.
• access_flags - The class’s access flags (see Opcodes).
• name - The internal name of the class.
• super_name - The internal name of the super class (e.g., java/lang/String, a/b/c). Use None for Object.
• interfaces - The internal names of the class’s interfaces.

fn visit_source(&mut self, _source: &str)

Visits the source file name of the class.

fn visit_module( &mut self, _name: &str, _access_flags: u16, _version: Option<&str>, ) -> Option<Box<dyn ModuleVisitor>>

Visits the JPMS module descriptor of this class, if this is a module-info.class.

fn visit_field( &mut self, _access_flags: u16, _name: &str, _descriptor: &str, ) -> Option<Box<dyn FieldVisitor>>

Visits a field of the class.

Returns an optional FieldVisitor to visit the field’s content.

fn visit_method( &mut self, _access_flags: u16, _name: &str, _descriptor: &str, ) -> Option<Box<dyn MethodVisitor>>

Visits a method of the class.

Returns an optional MethodVisitor to visit the method’s code.

fn visit_end(&mut self)

Visits the end of the class.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
