Make SpelNode compilation aware #32707
Description
Overview
SpelNodeImpl currently defines isCompilable() and generateCode(...) methods which make each SpelNodeImpl compilation aware; however, there are times when it would be beneficial to be able to invoke these methods via the SpelNode API – for example, for types within the org.springframework.expression.spel package that deal with compilation.
This is in fact a prerequisite for the forthcoming CompilableIndexAccessor.
