    - #### getBaseTypeName

          public java.lang.String getBaseTypeName()
                                           throws java.sql.SQLException

      Returns the SQL type name of the elements in the array designated by this `Array` object. If the elements are a built-in type, it returns the database-specific type name of the elements. If the elements are a user-defined type (UDT), this method returns the fully-qualified SQL type name.

        `getBaseTypeName` in interface `java.sql.Array`
      Returns:
        a `String` that is the database-specific name for a built-in base type or the fully-qualified SQL type name for a base type that is a UDT
      Throws:
        `java.sql.SQLException` - if an error occurs while attempting to access the type name

      Returns the JDBC type of the elements in the array designated by this `Array` object.
      Specified by:
        `getBaseType` in interface `java.sql.Array`
      Returns:

          public java.lang.Object getArray()
                                    throws java.sql.SQLException

      Retrieves the contents of the SQL `ARRAY` value designated by this `Array` object in the form of an array in the Java programming language. This version of the method `getArray` uses the type map associated with the connection for customizations of the type mappings.
      Specified by:
        `getArray` in interface `java.sql.Array`
      Returns:
        an array in the Java programming language that contains the ordered elements of the SQL `ARRAY` value designated by this object

      Retrieves the contents of the SQL array designated by this `Array` object. This method uses the specified `map` for type map customizations unless the base type of the array does not match a user-defined type in `map`, in which case it uses the standard mapping.

      Specified by:
        `getArray` in interface `java.sql.Array`
      Parameters:
        `map` - a `java.util.Map` object that contains mappings of SQL type names to classes in the Java programming language
      Returns:
        an array in the Java programming language that contains the ordered elements of the SQL array designated by this object
      Throws:
        `java.sql.SQLException` - if an error occurs while attempting to access the array

      Returns a result set that contains the elements of the SQL `ARRAY` value designated by this `Array` object. If appropriate, the elements of the array are mapped using the connection's type map; otherwise, the standard mapping is used.

      The result set contains one row for each array element, with two columns in each row. The second column stores the element value; the first column stores the index into the array for that element (with the first array element being at index 1). The rows are in ascending order corresponding to the order of the indices.

      Specified by:
        `getResultSet` in interface `java.sql.Array`
      Returns:
        a `ResultSet` object containing one row for each of the elements in the array designated by this `Array` object, with the rows in ascending order based on the indices.

      Parameters:
        `map` - contains the mapping of SQL user-defined types to classes in the Java programming language
      Returns:
        a `ResultSet` object containing one row for each of the elements in the array designated by this `Array` object, with the rows in ascending order based on the indices.

                                          throws java.sql.SQLException

      Returns a result set holding the elements of the subarray that starts at index `index` and contains up to `count` successive elements. This method uses the specified `map` for type map customizations unless the base type of the array does not match a user-defined type in `map`, in which case it uses the standard mapping. This version of the method `getResultSet` uses either the given type map or the standard mapping; it never uses the type map associated with the connection.

      The result set has one row for each element of the SQL array designated by this object, with the first row containing the element at index `index`. The result set has up to `count` rows in ascending order based on the indices. Each row has two columns: The second column stores the element value; the first column stroes the index into the array for that element.

    - #### free

          public void free()
                    throws java.sql.SQLException

      This method frees the `Array` object and releases the resources that it holds. The object is invalid once the `free` method is called.

      After `free` has been called, any attempt to invoke a method other than `free` will result in a `SQLException` being thrown. If `free` is called multiple times, the subsequent calls to `free` are treated as a no-op.

      Specified by:
        `free` in interface `java.sql.Array`
      Throws:
        `java.sql.SQLException` - if an error occurs releasing the Array's resources
        `java.sql.SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
      Since:
        1.6
