Class SimpleType.TypeDesc

java.lang.Object
acdp.design.SimpleType.TypeDesc
Enclosing class:
SimpleType<T>
protected static final class SimpleType.TypeDesc extends Object
Provides convenient access to the individual fields of a type descriptor that is represented by a String. This class can be used by implementers of a custom column type to validate a String representation of a type descriptor at the time the custom column type is created.
