Struct Hook 

pub struct Hook<'a>(/* private fields */);

An injection point reached, as a handler sees it.

Implementations

impl<'a> Hook<'a>

pub fn new(e: &'a mut Injected) -> Self

The point reached, to be changed.

pub fn this<T: Nanite>(&self) -> Option<T>

The object the method runs on (none in a static one).

pub fn arg<T: Java>(&self, i: usize) -> Option<T>

Argument i.

pub fn args(&self) -> usize

How many arguments there are.

pub fn value<T: Java>(&self) -> Option<T>

The value returned, at a RETURN.

pub fn cancel(&mut self)

Stops the method (a cancellable injection’s).

pub fn set_return<T: Java>(&mut self, value: T)

Stops the method returning value.

pub fn set_value<T: Java>(&mut self, value: T)

Makes value the answer: a modified value, a redirected call’s result.

pub fn call_original(&self, args: Vec<Value>) -> Option<Value>

Runs a redirected call as it was, with args (the receiver first): its result.

pub fn local<T: Java>(&self, i: usize) -> Option<T>

Local i of those the inject asked for.

pub fn set_local<T: Java>(&mut self, i: usize, value: T)

Sets local i (one the inject asked to write: & in locals).

pub fn cancelled(&self) -> bool

Whether a handler before this one stopped it.
