Example 1 with NeededCoverageSpec

use of com.facebook.buck.python.NeededCoverageSpec in project buck by facebook.

the class NeededCoverageSpecTypeCoercer method coerce.

@Override

            Iterator<?> iter = collection.iterator();
            Float neededRatio = floatTypeCoercer.coerce(cellRoots, filesystem, pathRelativeToProjectRoot, iter.next());
            if (neededRatio < 0 || neededRatio > 1) {
                throw CoerceFailedException.simple(object, getOutputClass(), "the needed coverage ratio should be in range [0; 1]");
            }
            BuildTarget buildTarget = buildTargetTypeCoercer.coerce(cellRoots, filesystem, pathRelativeToProjectRoot, iter.next());

            return NeededCoverageSpec.of(neededRatio, buildTarget, pathName);
        }
    }
    throw CoerceFailedException.simple(object, getOutputClass(), "input should be a tuple of needed coverage ratio, a build target, and optionally a path");
}

Example 2 with NeededCoverageSpec
