Interface Struct
- All Known Implementing Classes:
- SerialStruct
public interface Struct
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.

Method SummaryModifier and TypeMethodDescriptionObject[]Produces the ordered values of the attributes of the SQL structured type that thisStructobject represents.Object[]getAttributes(Map<String, Class<?>> map) Produces the ordered values of the attributes of the SQL structured type that thisStructobject represents.Retrieves the SQL type name of the SQL structured type that thisStructobject represents.
- 
Method Details- 
getSQLTypeNameRetrieves the SQL type name of the SQL structured type that thisStructobject 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
- Since:
- 1.2
 
- 
getAttributesProduces the ordered values of the attributes of the SQL structured type that thisStructobject 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 getObjecton 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
- Since:
- 1.2

getAttributesProduces the ordered values of the attributes of the SQL structured type that thisStructobject represents. As individual attributes are processed, 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 getObjecton 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
- Since:
- 1.2
