```
    Description copied from interface: VectorValueMatcherFactory
    
    Specialized value matcher for equality used by EqualityFilter. The matchValue parameter must be the appropriate Java type for the matchValueType ColumnType. Implementors can use this information to coerce the match value to the native type of the values to match against as necessary.
