40 * $Id$
41 *
42 * Created: [Apr 6, 2004]
43 *
44 * Defines a TRANSP iCalendar component property.
45 *
46 * <pre>
47 * 4.8.2.7 Time Transparency
48 *
49 * Property Name: TRANSP
50 *
51 * Purpose: This property defines whether an event is transparent or not
52 * to busy time searches.
53 *
54 * Value Type: TEXT
55 *
56 * Property Parameters: Non-standard property parameters can be
57 * specified on this property.
58 *
59 * Conformance: This property can be specified once in a &quot;VEVENT&quot;
60 * calendar component.
61 *
62 * Description: Time Transparency is the characteristic of an event that
63 * determines whether it appears to consume time on a calendar. Events
64 * that consume actual time for the individual or resource associated
65 * with the calendar SHOULD be recorded as OPAQUE, allowing them to be
66 * detected by free-busy time searches. Other events, which do not take
67 * up the individual's (or resource's) time SHOULD be recorded as
68 * TRANSPARENT, making them invisible to free-busy time searches.
69 *
70 * Format Definition: The property is specified by the following
71 * notation:
72 *
73 * transp = &quot;TRANSP&quot; tranparam &quot;:&quot; transvalue CRLF
74 *
75 * tranparam = *(&quot;;&quot; xparam)
76 *
77 * transvalue = &quot;OPAQUE&quot; ;Blocks or opaque on busy time searches.
78 * / &quot;TRANSPARENT&quot; ;Transparent on busy time searches.
79 * ;Default value is OPAQUE
80 *
81 * Example: The following is an example of this property for an event
82 * that is transparent or does not block on free/busy time searches:
83 *
84 * TRANSP:TRANSPARENT
85 *
86 * The following is an example of this property for an event that is
87 * opaque or blocks on free/busy time searches:
88 *
89 * TRANSP:OPAQUE
90 * </pre>
