Method Detail

getTypeVersion

int getTypeVersion()
                   throws SQLException

Throws:

SQLException

getLength

int getLength()
              throws SQLException

The number of fields in the Object Type.

Returns:

the size.

Throws:

SQLException

getMetaData

ResultSetMetaData getMetaData()
                              throws SQLException

Gets the metadata regarding this type. The return ResultSetMetaData contains the attribute name, attribute type id and attribute type precision information. The column index in ResultSetMetaData maps to the position of the attribute in a Struct (with the first attribute being at index 1).

Returns:

a ResultSetMetaData object that contains the type info

Throws:

if - database access error occurs

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:

SQLException
