Description:
|
We need some logic to be done before/after call of renderer for {{direct area rendering implementation}}. Although we have tried several places where it can be done, we agreed on usage of
so called
{{listeners}}
, see [DAR review II|https://www
.
evernote.com/shard/s260/sh/9bc8f54e-3909-47f0-8b37-b302be5a2901/a503a09d16ce4027962cb494025107d1].
Such set of
listener
listeners
is called before/after every call of render and we can reuse listeners in the future for different purposes (for example push/pop actions can be called in appropriate listeners).
- Register such listener in rendering engine config ({{RenderingContext}}).
- New instance of such listener per request.
- Registering of multiple listeners is possible.
- Listener is registered and instantiated by rendering engine and passed into rend. context.
