net.sf.farrago.type.runtime
Class EncodedSqlInterval

java.lang.Object
  net.sf.farrago.type.runtime.EncodedSqlInterval

All Implemented Interfaces:

AssignableValue, DataValue

Direct Known Subclasses:

EncodedSqlInterval.EncodedSqlIntervalDT, EncodedSqlInterval.EncodedSqlIntervalYM

public abstract class EncodedSqlInterval
extends Object
implements AssignableValue

Runtime type for interval values.

TODO:

• Need to include precision.
• Need to support casting from string, exact numerics
• Both of above would be easier if we just get the SqlIntervalQualifier
