Public Member Functions
	InternalCallStackManager (uint32_t context_id, EventEmitterInterface< InternalCallStackEvent > &emitter)

void	push (PC caller_pc, PC return_pc) override
	Push a new call onto the internal call stack. This is called when an internal call is executed. It pushes the caller_pc & return_pc to the stack. It also emits an internal call stack event.

PC	pop () override
	Pop the top call from the internal call stack. This is called when an internal return is executed. It pops the top call from the stack and returns the stored return_pc. It also emits an internal call stack event.

InternalCallId	get_next_call_id () const override
	Get the next call id.

InternalCallId	get_call_id () const override
	Get the current call id.

InternalCallId	get_return_call_id () const override
	Get the return call id.

std::vector< PC >	get_current_call_stack () const override
	Get the current call stack.

Member Function Documentation

◆ get_call_id()

InternalCallId bb::avm2::simulation::InternalCallStackManager::get_call_id ( ) const

overridevirtual

Get the current call id.

Returns: The current call id.

Implements bb::avm2::simulation::InternalCallStackManagerInterface.

◆ pop()

PC bb::avm2::simulation::InternalCallStackManager::pop ( )

overridevirtual

Pop the top call from the internal call stack. This is called when an internal return is executed. It pops the top call from the stack and returns the stored return_pc. It also emits an internal call stack event.

Returns: The program counter the caller will continue execution from.

Exceptions

InternalCallStackException if the internal call stack is empty.

Implements bb::avm2::simulation::InternalCallStackManagerInterface.

◆ push()

void bb::avm2::simulation::InternalCallStackManager::push	(	PC	caller_pc,
		PC	return_pc
	)

overridevirtual

Push a new call onto the internal call stack. This is called when an internal call is executed. It pushes the caller_pc & return_pc to the stack. It also emits an internal call stack event.
