combinedTransformer

public static BindingTransformer<?> combinedTransformer(Map<KeyPattern<?>,Set<BindingTransformer<?>>> transformers)

Modules export a priority multimap of transformers.

This transformer aggregates such map into one big generator to be used by Injector.compile(io.activej.inject.Injector, io.activej.inject.module.Module) method. The map is converted to a sorted list of sets. Then for each of those sets, similar to generators, only zero or one transformer from that set are allowed to return anything but the binding it was given (being an identity transformer).

So if two transformers differ in priority then they can be applied both in order of their priority.
