Interface Struct

All Known Implementing Classes:
SerialStruct

public interfaceStruct

The standard mapping in the Java programming language for an SQL structured type. AStruct 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 theStruct interface must be fully implemented if the JDBC driver supports the data type.

Since:
1.2

getAttributes()
          Produces the ordered values of the attributes of the SQL structured type that thisStruct object represents.
getAttributes(Map<String,Class<?>> map)
          Produces the ordered values of the attributes of the SQL structured type that thisStruct object represents.
getSQLTypeName()
          Retrieves the SQL type name of the SQL structured type that thisStruct object represents.
 

getSQLTypeName

StringgetSQLTypeName()                      throwsSQLException
Retrieves the SQL type name of the SQL structured type that thisStruct object represents.

Returns:
the fully-qualified type name of the SQL structured type for which thisStruct object 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

getAttributes

Object[]getAttributes()                       throwsSQLException
Produces the ordered values of the attributes of the SQL structured type that thisStruct 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 methodgetObject 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
Since:
1.2

getAttributes

Object[]getAttributes(Map<String,Class<?>> map)                       throwsSQLException
Produces the ordered values of the attributes of the SQL structured type that thisStruct 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 methodgetObject 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
Since:
1.2
