@SafeVarargs
static SizeInBytes getSizeInBytes(BiFunction<String, SizeInBytes, SizeInBytes> getter, String key, SizeInBytes defaultValue, BiConsumer<String, SizeInBytes>... assertions) {

    return value;
}

Example 2 with SizeInBytes

use of org.apache.ratis.util.SizeInBytes in project incubator-ratis by apache.
