Struct Method

pub struct Method { /* private fields */ }

Implementations

impl Method

pub fn new<S: AsRef<str>>( access_flags: MethodAccessFlags, name: S, descriptor: S, max_stack: usize, max_locals: usize, code: Vec<Instruction>, line_numbers: Vec<LineNumber>, exception_table: Vec<ExceptionTableEntry>, ) -> Result<Self>

Create a new class method

Errors

if the method descriptor cannot be parsed

pub fn from(class_file: &ClassFile, definition: &Method) -> Result<Self>

Create a new class method with the given definition.

Errors

if the method name cannot be read.

pub fn access_flags(&self) -> &MethodAccessFlags

Get the method access flags.

pub fn is_native(&self) -> bool

Check if the method is native.

pub fn is_static(&self) -> bool

Check if the method is static.

pub fn name(&self) -> &str

Get the method name.

pub fn descriptor(&self) -> &str

Get the method descriptor.

pub fn parameters(&self) -> &Vec<FieldType>

Get the method parameters.

pub fn return_type(&self) -> Option<&FieldType>

Get the method return type.

pub fn identifier(&self) -> String

Get the method identifier.

pub fn max_stack(&self) -> usize

Get the maximum stack size.

pub fn max_locals(&self) -> usize

Get the maximum number of local variables.

pub fn code(&self) -> &Vec<Instruction>

Get the code.

pub fn line_number(&self, program_counter: usize) -> usize

Get the line number for a given program counter.

Errors

if the program counter does not index into a valid line number

pub fn exception_table(&self) -> &Vec<ExceptionTableEntry>

Get the exception table.

pub fn parse_descriptor( descriptor: &str, ) -> Result<(Vec<FieldType>, Option<FieldType>)>

Parse the method descriptor. The descriptor is a string representing the method signature. The descriptor has the following format:

See: https://docs.oracle.com/javase/specs/jvms/se23/html/jvms-4.html#jvms-4.3.3

Errors

if the descriptor cannot be parsed

Trait Implementations

impl Clone for Method

fn clone(&self) -> Method

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Method

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Method

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Method

fn eq(&self, other: &Method) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
