hasBuildSteps

public final boolean hasBuildSteps()

Description copied from interface: BuildRule

Whether this BuildRule may have any steps to build.

Specified by:

Overrides:

hasBuildSteps in class AbstractBuildRule

getSourcePathToOutput

@Nullable
public SourcePath getSourcePathToOutput()

isCacheable

public final boolean isCacheable()

Description copied from interface: BuildRule

Whether this BuildRule can be cached.

Uncached build rules are never written out to cache, never read from cache, and does not count in cache statistics. This rule is useful for artifacts which cannot be easily normalized.

Uncached rules are not always rebuilt, however, as long as the existing on-disk representation is up to date. This means that these rules can take advantage of SupportsInputBasedRuleKey to prevent rebuilding.
