omni::ext::ExtensionStateChangeHookLambda

class ExtensionStateChangeHookLambda : public omni::ext::IExtensionStateChangeHook 

A wrapper object to allow passing an invocable type (i.e.

lambda) as an extension hook.

Public Functions

inline ExtensionStateChangeHookLambda(const std::function<void(const char*, ExtensionStateChangeType)> &fn)

Constructor.

Note

Typically this is not constructed directly. Instead use createExtensionStateChangeHook().

Parameters: fn – a std::function that will be called on extension state change. May be empty.

inline virtual void onStateChange(const char *extId, ExtensionStateChangeType type) override

State change handler function.

Note

Typically this is not called directly; it is called by ExtensionManager.

Parameters

inline virtual size_t addRef() override

Atomically adds one to the reference count.

Returns: The current reference count after one was added, though this value may change before read if other threads are also modifying the reference count. The return value is guaranteed to be non-zero.

inline virtual size_t release() override

Atomically subtracts one from the reference count.

If the result is zero, carb::deleteHandler() is called for this.

Returns: The current reference count after one was subtracted. If zero is returned, carb::deleteHandler() was called for this.

Public Static Functions

static inline constexpr carb::InterfaceDesc getInterfaceDesc() noexcept

Returns information about this interface.

Auto-generated by CARB_PLUGIN_INTERFACE() or CARB_PLUGIN_INTERFACE_EX.

Returns: The carb::InterfaceDesc struct with information about this interface.

static inline constexpr carb::InterfaceDesc getLatestInterfaceDesc() noexcept

Returns information about the latest version of this interface.

Auto-generated by CARB_PLUGIN_INTERFACE() or CARB_PLUGIN_INTERFACE_EX.

Returns: The carb::InterfaceDesc struct with information about the latest version of this interface.
