Method Detail
-
getTypeVersion
int getTypeVersion() throws SQLException
- Throws:
SQLException
-
getLength
int getLength() throws SQLException

-
isFinalType
boolean isFinalType() throws SQLException
Indicates whether the object type is a final type.- Returns:
- true if the object type is a final type and false otherwise.
- Throws:
SQLException
-
isSubtype
boolean isSubtype() throws SQLException
Indicates whether the object type is a subtype.- Returns:
- true if the object type is a subtype and false otherwise.
- Throws:
SQLException
-
isInstantiable
boolean isInstantiable() throws SQLException
Indicates whether the object type is instantiable.- Returns:
- true if the object type is instantiable and false otherwise.
- Throws:
SQLException
-
getSupertypeName
String getSupertypeName() throws SQLException
Returns the SQL type name of the direct subtype.- Returns:
- the fully qualified name of the supertype. Returns null if the object type is not a subtype.
- Throws:
SQLException
-
getLocalAttributeCount
int getLocalAttributeCount() throws SQLException
Returns the number of attributes defined in the subtype.- Returns:
- number of subtype attributes.
- Throws:
SQLException
-
getSubtypeNames
String[] getSubtypeNames() throws SQLException
Returns the SQL type names of the direct subtypes.- Returns:
- the fully qualifed name of the direct subtypes. Returns an empty String array if there is no subtypes.
- Throws:
