The standard mapping in the Java programming language for an SQL
structured type. A Struct object contains a
value for each attribute of the SQL structured type that
it represents.
By default, an instance ofStruct is valid as long as the
application has a reference to it.
All methods on the Struct interface must be fully implemented if the
JDBC driver supports the data type.
Public Method Summary
| abstract Object[] |
getAttributes()
Produces the ordered values of the attributes of the SQL
structured type that this
Struct object represents. |
| abstract Object[] |
getAttributes(Map<String, Class<?>> map)
Produces the ordered values of the attributes of the SQL
structured type that this
Struct object represents. |
| abstract String |
getSQLTypeName()
Retrieves the SQL type name of the SQL structured type
that this
Struct object represents. |
Public Methods
public abstract Object[] getAttributes ()
Produces the ordered values of the attributes of the SQL
structured type that this Struct object represents.
As individual attributes are processed, this method uses the type map
associated with the
connection for customizations of the type mappings.
If there is no
entry in the connection's type map that matches the structured
type that an attribute represents,
the driver uses the standard mapping.
Conceptually, this method calls the method
getObject on each attribute
of the structured type and returns a Java array containing
the result.
Returns
- an array containing the ordered attribute values
Throws
| SQLException | if a database access error occurs |
|---|---|
| SQLFeatureNotSupportedException | if the JDBC driver does not support this method |
public abstract Object[] getAttributes (Map<String, Class<?>> map)
Produces the ordered values of the attributes of the SQL
structured type that this Struct object represents.
As individual attrbutes are proccessed, this method uses the given type map
for customizations of the type mappings.
If there is no
entry in the given type map that matches the structured
type that an attribute represents,
the driver uses the standard mapping. This method never
uses the type map associated with the connection.
Conceptually, this method calls the method
getObject on each attribute
of the structured type and returns a Java array containing
the result.
Parameters
| map | a mapping of SQL type names to Java classes |
|---|
Returns
- an array containing the ordered attribute values
Throws
| SQLException | if a database access error occurs |
|---|---|
| SQLFeatureNotSupportedException | if the JDBC driver does not support this method |
public abstract String getSQLTypeName ()
Retrieves the SQL type name of the SQL structured type
that this Struct object represents.
Returns
- the fully-qualified type name of the SQL structured
type for which this
Structobject is the generic representation
Throws
| SQLException | if a database access error occurs |
|---|---|
| SQLFeatureNotSupportedException | if the JDBC driver does not support this method |
