Contained in package wwpre_api_value.

Call this function to get the preference value as a number.

Note: For details about returning preference values, see About preference values.

function get_value_as_number

(

p_path in varchar2,

p_name in varchar2,

p_level_type in varchar2 default INHERIT_LEVEL_TYPE,

p_level_name in varchar2 default null

)

return number;

Version: Oracle Portal 3.0.6.6.5 or later

Parameters:

p_path

The path for the preference name.

Datatype: in varchar2

p_name

The preference name.

Datatype: in varchar2

p_level_type

A constant value for the level at which the value is retrieved.

Note: If a value is not specified for p_level_type, this function attempts to inherit the value, moving to each step if a value is not found:

  1. Get the value for the user currently logged in.

  2. Get the default group value for the user currently logged in.
  3. Get the value for the system level type.
  4. Return null

Datatype: in varchar2
Default: INHERIT_LEVEL_TYPE

p_level_name

The user name or group name for the value to be retrieved.

Notes:

  • If not specified, this method searches for a valid value based on path, name, and level type.

  • For user-level or group-level type, the level name or level ID must be specified.

Datatype: in varchar2
Default: null

Returns:

This function returns the number value of a specified preference. It returns null if there is no value, or if the preference name is not found.

Exceptions:

  • If the path is not found, a PATH_NOT_FOUND_EXCEPTION is raised.

  • If a duplicate path is found, a DUPLICATE_PATH_EXCEPTION is raised.
  • If the value has not been stored, a GENERAL_PREFERENCE_EXCEPTION is raised.

Example:

This example returns the value based on the inherit mechanism.

l_number_value := wwpre_api_value.get_value_as_number

(

p_path => 'ORACLE.PORTAL.TEST.STYLE.DEFAULT',

p_name => 'FONT_SIZE',

p_level_type => wwpre_api_value.GROUP_LEVEL_TYPE,

p_level_name => 'TEST_GROUP'

);
