Public Functions Documentation

function EventHandler

inline EventHandler(
    Functor functor
)

function Invoke

inline virtual void Invoke(
    ArgumentsBinder * binder
)

Invoke the handler using the provided arguments binder.

Parameters:

• binder Binder used to read arguments and write return values

Note

This method is called when the bound method or event is triggered from the scripting environment. Implementations are expected to read the arguments from binder, perform the desired action, and optionally write a return value back through the binder.

Reimplements: cohtml::IEventHandler::Invoke

function SetTarget

inline virtual void SetTarget(
    void * target
)

Set the current invocation target.

Parameters:

• target Pointer to the target object for the upcoming invocation

Note

This method is called by the SDK before each invocation to ensure the handler is associated with the correct target object. Implementations should store the pointer and use it during Invoke().

Reimplements: cohtml::IEventHandler::SetTarget

function GetTarget

inline virtual const void * GetTarget()

Retrieve the current invocation target.

Return: Pointer to the current target object

Note

The returned pointer represents the object instance on which the method is being invoked, or an abstraction meaningful to the handler implementation.

Reimplements: cohtml::IEventHandler::GetTarget
