Struct MethodVisitor 

pub struct MethodVisitor { /* private fields */ }

A visitor to visit a Java method.

Used to generate the bytecode instructions, exception tables, and attributes for a specific method.

Implementations

impl MethodVisitor

pub fn new(access_flags: u16, name: &str, descriptor: &str) -> Self

pub fn visit_code(&mut self) -> &mut Self

Starts the visit of the method’s code.

pub fn visit_insn(&mut self, opcode: u8) -> &mut Self

Visits a zero-operand instruction (e.g., NOP, RETURN).

pub fn visit_var_insn(&mut self, opcode: u8, var_index: u16) -> &mut Self

Visits a local variable instruction (e.g., ILOAD, ASTORE).

pub fn visit_field_insn( &mut self, opcode: u8, owner: &str, name: &str, descriptor: &str, ) -> &mut Self

Visits a field instruction (e.g., GETFIELD, PUTSTATIC).

pub fn visit_method_insn( &mut self, opcode: u8, owner: &str, name: &str, descriptor: &str, _is_interface: bool, ) -> &mut Self

Visits a method instruction (e.g., INVOKEVIRTUAL).

pub fn visit_jump_insn(&mut self, opcode: u8, target: Label) -> &mut Self

pub fn visit_label(&mut self, label: Label) -> &mut Self

pub fn visit_line_number(&mut self, line: u16, start: LabelNode) -> &mut Self

pub fn visit_ldc_insn(&mut self, value: LdcInsnNode) -> &mut Self

Visits a constant instruction (LDC).

pub fn visit_maxs(&mut self, max_stack: u16, max_locals: u16) -> &mut Self

Visits the maximum stack size and number of local variables.

If COMPUTE_MAXS or COMPUTE_FRAMES was passed to the ClassWriter, these values may be ignored or recomputed.

pub fn visit_end(self, class: &mut ClassWriter)

Finalizes the method and attaches it to the parent ClassWriter.
