Examples with CompositeExclude org.gradle.api.internal.artifacts.ivyservice.resolveengine.excludes.specs.CompositeExclude used on opensource projects

Example 1 with CompositeExclude

use of org.gradle.api.internal.artifacts.ivyservice.resolveengine.excludes.specs.CompositeExclude in project gradle by gradle.

the class NormalizingExcludeFactory method flatten.

/**
 * Flattens a collection of elements that are going to be joined or intersected. There
 * are 3 possible outcomes:
 * - null means that the fast exit condition was reached, meaning that the caller knows it's not worth computing more
 * - empty list meaning that an easy simplification was reached and we directly know the result
 * - flattened unions/intersections
