Struct noak::descriptor::MethodDescriptor

pub struct MethodDescriptor<'a> { /* private fields */ }

A method descriptor specifies the parameter types and return type of a method.

Implementations

impl<'a> MethodDescriptor<'a>

pub fn parse(input: &'a MStr) -> Result<MethodDescriptor<'a>, DecodeError>

Parses a method descriptor as described in §4.3.3.

Examples

use noak::descriptor::{BaseType, MethodDescriptor, TypeDescriptor};
use noak::MStr;

let descriptor = MethodDescriptor::parse(MStr::from_mutf8(b"(Ljava/lang/String;)I").unwrap()).unwrap();
assert_eq!(descriptor.parameters().count(), 1);
assert_eq!(descriptor.return_type(), Some(TypeDescriptor { dimensions: 0, base: BaseType::Integer }));

pub fn parameters(&self) -> impl Iterator<Item = TypeDescriptor<'a>> + 'a

Returns an iterator over the method parameters.

pub fn return_type(&self) -> Option<TypeDescriptor<'a>>

Returns the return type of this method descriptor. If the return type is void (V), then None is returned.
