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: Get the value for the user currently logged in. Get the default group value for the user currently logged in. Get the value for the system level type. 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' );
