icalendar.prop.dt.list module

class icalendar.prop.dt.list.vDDDLists(dt_list, params=None)

Bases: object

A list of vDDDTypes values.

property VALUE: str

The VALUE parameter or the default.

Purpose:

VALUE explicitly specify the value type format for a property value.

Description:

This parameter specifies the value type and format of the property value. The property values MUST be of a single value type. For example, a "RDATE" property cannot have a combination of DATE-TIME and TIME value types.

If the property's value is the default value type, then this parameter need not be specified. However, if the property's default value type is overridden by some other allowable value type, then this parameter MUST be specified.

Applications MUST preserve the value data for x-name and iana-token values that they don't recognize without attempting to interpret or parse the value data.

Returns:

The VALUE parameter or the default.

Examples

The VALUE defaults to the name of the property. Note that it is case-insensitive but always uppercase.

>>> from icalendar import vBoolean
>>> b = vBoolean(True)
>>> b.VALUE
'BOOLEAN'

Setting the VALUE parameter of a typed property usually does not make sense. For convenience, using this property, the value will be converted to an uppercase string. If you have some custom property, you might use it like this:

>>> from icalendar import vUnknown, Event
>>> v = vUnknown("Some property text.")
>>> v.VALUE = "x-type"  # lower case
>>> v.VALUE
'X-TYPE'
>>> event = Event()
>>> event.add("x-prop", v)
>>> print(event.to_ical())
BEGIN:VEVENT
X-PROP;VALUE=X-TYPE:Some property text.
END:VEVENT

Setter accepts:

str | None

default_value: ClassVar[str] = 'DATE-TIME'

property dt: TimeBase

Return the time/date value of the list.

This is a compatibility method for the vDDDTypes interface.

Returns:

The first value of the list.

Raises:

IndexError – If the list is empty.
