All Implemented Interfaces:

java.lang.AutoCloseable

Direct Known Subclasses:

BytewiseComparator

public abstract class Comparator
extends AbstractComparator<Slice>

Base class for comparators which will receive byte[] based access via org.rocksdb.Slice in their compare method implementation. byte[] based slices perform better when small keys are involved. When using larger keys consider using @see org.rocksdb.DirectComparator
