ICalendar (biweekly 0.6.8 API)

java.lang.Object
- biweekly.component.ICalComponent
- - biweekly.ICalendar

public class ICalendar
extends ICalComponent

Represents an iCalendar object.

Examples:

 ICalendar ical = new ICalendar();
 
 VEvent event = new VEvent();
 event.setSummary("Team Meeting");
 Date start = ...;
 event.setDateStart(start);
 Date end = ...;
 event.setDateEnd(end);
 ical.addEvent(event);

Getting timezone information from parsed iCalendar objects:

 //The timezone information associated with an ICalendar object is stored in its TimezoneInfo object.
 ICalReader reader = ...
 ICalendar ical = reader.readNext();
 TimezoneInfo tzinfo = ical.getTimezoneInfo();
 
 //You can use this object to get the VTIMEZONE components that were parsed from the input stream.
 //Note that the VTIMEZONE components will NOT be in the ICalendar object itself
 Collection<VTimezone> vtimezones = tzinfo.getComponents();
 
 //You can also get the timezone that a specific property was originally formatted in.
 DateStart dtstart = ical.getEvents().get(0).getDateStart();
 TimeZone tz = tzinfo.getTimezone(dtstart).getTimeZone();
 
 //This is useful for calculating recurrence rule dates.
 RecurrenceRule rrule = ical.getEvents(0).getRecurrenceRule();
 DateIterator it = rrule.getDateIterator(dtstart.getValue(), tz);

Setting timezone information when writing iCalendar objects:

 //The TimezoneInfo field is used to determine what timezone to format each date-time value in when the ICalendar object is written.
 //Appropriate VTIMEZONE components are automatically added to the written iCalendar object.
 ICalendar ical = ...
 TimezoneInfo tzinfo = ical.getTimezoneInfo();
 
 //biweekly uses the TimezoneAssignment class to define timezones.
 //This class groups together a Java TimeZone object, which is used to format/parse the date-time values, and its equivalent VTIMEZONE component definition.
 
 //biweekly can auto-generate the VTIMEZONE definitions by downloading them from tzurl.org.
 //If you want the generated VTIMEZONE components to be tailored for Microsoft Outlook email clients, pass "true" into this method.
 TimezoneAssignment timezone = TimezoneAssignment.download(TimeZone.getTimeZone("America/New_York"), true);
 
 //Using the TimezoneAssignment class, you can specify what timezone you'd like to format all date-time values in.
 tzinfo.setDefaultTimezone(timezone);
 
 //You can also specify what timezone to use for individual properties if you want.
 DateStart dtstart = ical.getEvents(0).getDateStart();
 TimezoneAssignment losAngeles = TimezoneAssignment.download(TimeZone.getTimeZone("America/Los_Angeles"), true);
 tzinfo.setTimezone(dtstart, losAngeles);
 
 //The writer object will use this information to determine what timezone to format each date-time value in.
 //Date-time values are formatted in UTC by default.
 ICalWriter writer = ...
 writer.write(ical);

```
    Sets the version of this iCalendar object.
    
    Parameters:
    
    version - the version
  - getTimezoneInfo
```
public TimezoneInfo getTimezoneInfo()
```
    Gets the timezone information associated with this iCalendar object.
    
    When an iCalendar object is parsed from an input stream, the TimezoneInfo object remembers the original timezone definitions that each property was associated with. One use for this is when you want to calculate the dates in a recurrence rule. The recurrence rule needs to know what timezone its associated date values were originally formatted in in order to work correctly.
    
    When an ICalendar object is written to an output stream, its TimezoneInfo object tells the writer what timezone to format each property in.
    
    Returns:
    
    the timezone info

  - validate
```
public ValidationWarnings validate(ICalVersion version)
```
    Checks this iCalendar object for data consistency problems or deviations from the specifications.
    
    The existence of validation warnings will not prevent the iCalendar object from being written to a data stream. Syntactically-correct output will still be produced. However, the consuming application may have trouble interpreting some of the data due to the presence of these warnings.
    
    These problems can largely be avoided by reading the Javadocs of the component and property classes, or by being familiar with the iCalendar standard.
    
    Parameters:
    
    version - the version to validate against
    
    Returns:
    
    the validation warnings
  - validate
```
protected void validate(List<ICalComponent> components,
                        ICalVersion version,
                        List<ValidationWarning> warnings)
```
    Description copied from class: ICalComponent
    
    Checks the component for data consistency problems or deviations from the spec.
    
    This method should be overridden by child classes that wish to provide validation logic. The default implementation of this method does nothing.
    
    Overrides:
    
    validate in class ICalComponent
    
    Parameters:
    
    components - the hierarchy of components that the component belongs to
    
    version - the version to validate against
    
    warnings - the list to add the warnings to
