What's changed?

Adding three new building recipes for No Guava recipe:

  • NoGuavaImmutableListCopyOf
  • NoGuavaImmutableSetCopyOf
  • NoGuavaImmutableMapCopyOf

modelled after (or actually now sharing code with) the existing:

  • NoGuavaImmutableListOf
  • NoGuavaImmutableMapOf
  • NoGuavaImmutableSetOf

What's your motivation?

Looking at the comments on

(a previous attempt), would it have made more sense to have an AbstractNoGuavaImmutable that has the generic logic and intermediate layers being AbstractNoGuavaImmutableOf and AbstractNoGuavaImmutableCopyOf that would provide the copyOf or of method name rather than bringing that down to the individual recipes and changing the signature of the AbstractNoGuavaImmutableOf?

intermediate layers

To be honest, that was one of the options I have considered. But this looked like somewhat artificial exercise in OOP.
Happy to adapt to it, if we agree on this.

Merging, we can always consider refaxtoring the code later on.
