org.dbunit.dataset.datatype.AbstractDataType
public abstract class AbstractDataType
Abstract data type implementation that provides generic methods that are
appropriate for most data type implementations. Among those is the
generic implementation of the compare(Object, Object)
method.

The two values are typecast to this DataType before being compared.

implemented by a specialized DataType
implementation.
