Class PreDexSplitDexGroup

java.lang.Object

com.facebook.buck.core.rules.impl.AbstractBuildRule

com.facebook.buck.core.rules.impl.AbstractBuildRuleWithDeclaredAndExtraDeps

com.facebook.buck.android.PreDexSplitDexGroup

All Implemented Interfaces:

BuildEngineAction, AllowsNonAnnotatedFields, HasDeclaredAndExtraDeps, InitializableFromDisk<com.facebook.buck.android.PreDexSplitDexGroup.BuildOutput>, SupportsInputBasedRuleKey, BuildRule, HasNameAndType, Comparable<BuildRule>

public class PreDexSplitDexGroup
extends AbstractBuildRuleWithDeclaredAndExtraDeps
implements InitializableFromDisk<com.facebook.buck.android.PreDexSplitDexGroup.BuildOutput>, SupportsInputBasedRuleKey

Takes a subset of the predexed libraries (for a single APKModule) and produces copies of the predexed libraries to be merged into the primary dex, and a set of secondary dexes, capped at the dex weight limit.

Separating this from PreDexSplitDexMerge and making it cacheable makes it possible to fetch a much smaller set of artifacts from cache when the predexed libraries are invalidated.
