# LateBoundDefault

{% dynamic setvar source_file "src/main/java/com/google/devtools/build/lib/starlarkbuildapi/LateBoundDefaultApi.java" %} {% dynamic setvar version "8.3.0" %} {% dynamic setvar original_path "/rules/lib/builtins/LateBoundDefault" %} {% include "_buttons.html" %} Represents a late-bound default attribute value of type 'Label'. The value of a LateBoundDefault is only resolvable in the context of a rule implementation function, and depends on the current build configuration. For example, a LateBoundDefault might represent the Label of the java toolchain in the current build configuration.

See configuration_field for example usage.
