Class HybridLocalStrategy

java.lang.Object

com.facebook.buck.rules.modern.builders.HybridLocalStrategy

All Implemented Interfaces:

BuildRuleStrategy, Closeable, AutoCloseable

public class HybridLocalStrategy
extends Object
implements BuildRuleStrategy

This build strategy sends jobs to both a delegate build strategy and to the build engine to be run in the default way.

It has a configurable limit for the number of active jobs to allow locally, and for the number to allow to the delegate. It prefers to send them locally if the limit there hasn't been reached. If both are at the limit, the jobs will be queued until space becomes available.
