Member Function Documentation

◆ expand()

Sabre\VObject\Component\VCalendar::expand	(	DateTimeInterface	$start,
		DateTimeInterface	$end,
		DateTimeZone	$timeZone = `null`
	)

Expand all events in this VCalendar object and return a new VCalendar with the expanded events.

If this calendar object, has events with recurrence rules, this method can be used to expand the event into multiple sub-events.

Each event will be stripped from it's recurrence information, and only the instances of the event in the specified timerange will be left alone.

In addition, this method will cause timezone information to be stripped, and normalized to UTC.

Parameters

DateTimeInterface	$start
DateTimeInterface	$end
DateTimeZone	$timeZone	reference timezone for floating dates and times.

Returns: VCalendar

◆ validate()

Validates the node for correctness.

The following options are supported: Node::REPAIR - May attempt to automatically repair the problem. Node::PROFILE_CARDDAV - Validate the vCard for CardDAV purposes. Node::PROFILE_CALDAV - Validate the iCalendar for CalDAV purposes.

This method returns an array with detected problems. Every element has the following properties:

level - problem level.
message - A human-readable string describing the issue.
node - A reference to the problematic node.

The level means: 1 - The issue was repaired (only happens if REPAIR was turned on). 2 - A warning. 3 - An error.

Parameters

int $options

Returns: array
