NAME

DAIA::Unavailable - Information about a service that is currently unavailable

DESCRIPTION

This class is derived from DAIA::Availability - see that class for details. In addition there are the properties expected and queue. Obviously the status property of a DAIA::Unavailable object is always 0.

PROPERTIES

href

limitation

message

queue

The number of waiting requests for this service as non-negative integer value. Note that the value 0 is also allowed but in practise there is litte difference between no queue and a queue of length zero.

expected

An optional time period until the service will be available again. The property is given as ISO time period string (as XML Schema subset xs:date or xs:dateTime) or the special value "unknown". If no period (nor "unknown") is given, the service probably won't be available in the future.

FUNCTIONS

normalize_date ( $date-or-datetime )

Returns a canonical xs:date or xs:dateTime value or undef. Can can pass a DateTime object or a string that will be parsed with the parse_datetime method of DateTime::Format::ISO8601.
