Package org.eolang.maven.objectionary

Class OyFallbackSwap

java.lang.Object

org.eolang.maven.objectionary.OyFallbackSwap

All Implemented Interfaces:

Objectionary

public final class OyFallbackSwap
extends Object
implements Objectionary

Fallback which can swap primary/secondary repos.

The key purpose of this class is to allow dynamic determination of which Oy (fist or second) to use as primary and which as fallback based on given boolean property.

For PullMojo this is used to bypass reading from cache by always checking remote first and only fallback to local in case of object miss:

     new PullMojo.FallbackSwapOy(
         < local >,
         < remote >,
         this.forceUpdate()
     );
