copy()
Creates a deep copy of this emitter.

- the render context which provides access to the local and global environment and also the target
for the generated textException
- all thrown exceptions are caught and converted into a RenderException
public Emitter copy()
Emitter
When templates are inlined, the parameters are propagated and constant expressions and conditions are evaluated at compile time. This yields faster and more efficient templates. In order to perform these optimizations, we need a copy of the template and all its emitters which can safely be modified.
public Emitter reduce()
Emitter
Certain emitters can perform optimizations (evaluate constant expressions, combine constant outputs etc.) to create more efficient templates. This is especially important when a template is inlined, as this most probably provides a higher level of optimizations.
