- * 4.8.6.3 Trigger - * - * Property Name: TRIGGER - * - * Purpose: This property specifies when an alarm will trigger. - * - * Value Type: The default value type is DURATION. The value type can be - * set to a DATE-TIME value type, in which case the value MUST specify a - * UTC formatted DATE-TIME value. - * - * Property Parameters: Non-standard, value data type, time zone - * identifier or trigger relationship property parameters can be - * specified on this property. The trigger relationship property - * parameter MUST only be specified when the value type is DURATION. - * - * Conformance: This property MUST be specified in the "VALARM" calendar - * component. - * - * Description: Within the "VALARM" calendar component, this property - * defines when the alarm will trigger. The default value type is - * DURATION, specifying a relative time for the trigger of the alarm. - * The default duration is relative to the start of an event or to-do - * that the alarm is associated with. The duration can be explicitly set - * - * to trigger from either the end or the start of the associated event - * or to-do with the "RELATED" parameter. A value of START will set the - * alarm to trigger off the start of the associated event or to-do. A - * value of END will set the alarm to trigger off the end of the - * associated event or to-do. - * - * Either a positive or negative duration may be specified for the - * "TRIGGER" property. An alarm with a positive duration is triggered - * after the associated start or end of the event or to-do. An alarm - * with a negative duration is triggered before the associated start or - * end of the event or to-do. - * - * The "RELATED" property parameter is not valid if the value type of - * the property is set to DATE-TIME (i.e., for an absolute date and time - * alarm trigger). If a value type of DATE-TIME is specified, then the - * property value MUST be specified in the UTC time format. If an - * absolute trigger is specified on an alarm for a recurring event or - * to-do, then the alarm will only trigger for the specified absolute - * date/time, along with any specified repeating instances. - * - * If the trigger is set relative to START, then the "DTSTART" property - * MUST be present in the associated "VEVENT" or "VTODO" calendar - * component. If an alarm is specified for an event with the trigger set - * relative to the END, then the "DTEND" property or the "DSTART" and - * "DURATION' properties MUST be present in the associated "VEVENT" - * calendar component. If the alarm is specified for a to-do with a - * trigger set relative to the END, then either the "DUE" property or - * the "DSTART" and "DURATION' properties MUST be present in the - * associated "VTODO" calendar component. - * - * Alarms specified in an event or to-do which is defined in terms of a - * DATE value type will be triggered relative to 00:00:00 UTC on the - * specified date. For example, if "DTSTART:19980205, then the duration - * trigger will be relative to19980205T000000Z. - * - * Format Definition: The property is defined by the following notation: - * - * trigger = "TRIGGER" (trigrel / trigabs) - * - * trigrel = *( - * - * ; the following are optional, - * ; but MUST NOT occur more than once - * - * (";" "VALUE" "=" "DURATION") / - * (";" trigrelparam) / - * - * ; the following is optional, - * ; and MAY occur more than once - * - * (";" xparam) - * ) ":" dur-value - * - * trigabs = 1*( - * - * ; the following is REQUIRED, - * ; but MUST NOT occur more than once - * - * (";" "VALUE" "=" "DATE-TIME") / - * - * ; the following is optional, - * ; and MAY occur more than once - * - * (";" xparam) - * - * ) ":" date-time - *- * - * @author Ben Fortuna - */ -public class Trigger extends UtcProperty { - - private static final long serialVersionUID = 5049421499261722194L; - - private Dur duration; - - /** - * Default constructor. - */ - public Trigger() { - super(TRIGGER, PropertyFactoryImpl.getInstance()); - } - - /** - * @param aList a list of parameters for this component - * @param aValue a value string for this component - */ - public Trigger(final ParameterList aList, final String aValue) { - super(TRIGGER, aList, PropertyFactoryImpl.getInstance()); - setValue(aValue); - } - - /** - * @param duration a duration in milliseconds - */ - public Trigger(final Dur duration) { - super(TRIGGER, PropertyFactoryImpl.getInstance()); - setDuration(duration); - } - - /** - * @param aList a list of parameters for this component - * @param duration a duration in milliseconds - */ - public Trigger(final ParameterList aList, final Dur duration) { - super(TRIGGER, aList, PropertyFactoryImpl.getInstance()); - setDuration(duration); - } - - /** - * @param dateTime a date representation of a date-time - */ - public Trigger(final DateTime dateTime) { - super(TRIGGER, PropertyFactoryImpl.getInstance()); - setDateTime(dateTime); - } - - /** - * @param aList a list of parameters for this component - * @param dateTime a date representation of a date-time - */ - public Trigger(final ParameterList aList, final DateTime dateTime) { - super(TRIGGER, aList, PropertyFactoryImpl.getInstance()); - setDateTime(dateTime); - } - - /** - * {@inheritDoc} - */ - public final void validate() throws ValidationException { - super.validate(); - - final Parameter relParam = getParameter(Parameter.RELATED); - final Parameter valueParam = getParameter(Parameter.VALUE); - - if (relParam != null || !Value.DATE_TIME.equals(valueParam)) { - - ParameterValidator.getInstance().assertOneOrLess(Parameter.RELATED, - getParameters()); - - ParameterValidator.getInstance().assertNullOrEqual(Value.DURATION, - getParameters()); - - if (getDuration() == null) { - throw new ValidationException("Duration value not specified"); - } - } - else { - ParameterValidator.getInstance().assertOne(Parameter.VALUE, - getParameters()); - - ParameterValidator.getInstance().assertNullOrEqual(Value.DATE_TIME, - getParameters()); - - if (getDateTime() == null) { - throw new ValidationException("DATE-TIME value not specified"); - } - } - } - - /** - * @return Returns the duration. - */ - public final Dur getDuration() { - return duration; - } - - /** - * {@inheritDoc} - */ - public final void setValue(final String aValue) { - try { - super.setValue(aValue); - duration = null; - } - catch (ParseException pe) { - duration = new Dur(aValue); - super.setDateTime(null); - } - } - - /** - * {@inheritDoc} - */ - public final String getValue() { - if (duration != null) { - return duration.toString(); - } - return super.getValue(); - } - - /** - * @param dateTime The dateTime to set. - */ - public final void setDateTime(final DateTime dateTime) { - super.setDateTime(dateTime); - duration = null; - getParameters().replace(Value.DATE_TIME); - } - - /** - * @param duration The duration to set. - */ - public final void setDuration(final Dur duration) { - this.duration = duration; - super.setDateTime(null); - // duration is the default value type for Trigger.. - if (getParameter(Parameter.VALUE) != null) { - getParameters().replace(Value.DURATION); - } - } -}
