Implementations

impl Frame

pub fn from_kind(kind: FrameKind) -> Self

Construct a new empty frame from its kind.

pub fn kind(&self) -> &FrameKind

Get the frame’s kind.

pub fn get_self(&self) -> Value

Get the self value for this frame.

pub fn get_method_holder(&self) -> SOMRef<Class>

Get the holder for this current method.

pub fn get_method(&self) -> Rc<Method>

Get the current method itself.

pub fn get_bytecode(&self, idx: usize) -> Option<Bytecode>

Get the bytecode at the specified index for the current method.

pub fn get_current_bytecode(&self) -> Option<Bytecode>
