public class DataTypeUsage
To "use" a DataType is to refere to it by ID and store values for any attributes that DataType may have (e.g. precision, scale, size). All attribute values are stored in a map against that attribute's name. The ID of the DataType being used is also stored.
A DataTypeUsage can be "validated" by its corresponding DataType.
This replaces the deprecated way of storing scale and precision on a Column which was not flexible enough to support all datatype attributes.
To get a String representation of the usage and attributes use the
DataType.getDDL(oracle.javatools.db.datatypes.DataTypeUsage)
method.
Code examples for using DataTypeUsages are available in the datatypes
