Method Detail

of

public static DefaultBuildTargetSourcePath of(BuildTarget target)

Returns a default BuildTargetSourcePath with an empty output label.

of

public static DefaultBuildTargetSourcePath of(BuildTargetWithOutputs targetWithOutputs)

Construct a new immutable DefaultBuildTargetSourcePath instance.

Parameters:

targetWithOutputs - The value for the targetWithOutputs attribute

Returns:

An immutable DefaultBuildTargetSourcePath instance

of

public static DefaultBuildTargetSourcePath of(BuildTargetWithOutputs targetWithOutputs,
                                              Optional<? extends com.google.common.hash.HashCode> precomputedHash)

getTargetWithOutputs

public abstract BuildTargetWithOutputs getTargetWithOutputs()

Specified by:

getTargetWithOutputs in interface BuildTargetSourcePath

Returns:

the BuildTargetWithOutputs this SourcePath is associated with

getPrecomputedHash

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

Description copied from interface: BuildTargetSourcePath

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.

Specified by:

getPrecomputedHash in interface BuildTargetSourcePath
