Interface BuildTargetSourcePath

All Superinterfaces:

Comparable<SourcePath>, SourcePath

All Known Implementing Classes:

DefaultBuildTargetSourcePath, ExplicitBuildTargetSourcePath, ForwardingBuildTargetSourcePath

public interface BuildTargetSourcePath
extends SourcePath

A SourcePath which resolves to some output generated by a BuildRule.

The file is not guaranteed to exist until the BuildRule has been built.

Method Summary

Method Detail

getTargetWithOutputs

BuildTargetWithOutputs getTargetWithOutputs()

Returns:

the BuildTargetWithOutputs this SourcePath is associated with

getTarget

default BuildTarget getTarget()

Returns:

the target of the BuildRule which generates the file.

getPrecomputedHash

Optional<com.google.common.hash.HashCode> getPrecomputedHash()

In rare cases, a BuildTargetSourcePath may know a hash of its content on disk before it even creates its output. In this case, we can skip hashing its output files entirely and simply use this precomputed hash code. Use Optional.empty() in the common case.

representationForRuleKey

default String representationForRuleKey()

Returns:

a string representation that is usable for rule keys, i.e. does not depend on absolute paths
