63 * Next assignment to the option clears old values.
65 * This flag is set when a new option source starts, such that values

69 //! %Option is required to be set.
71 //! %Option can be specified multiple times.
73 //! %Option is hidden from standard help.
76 * %Option value is a vector, but a single value is also accepted.
78 * If only a single value is provided, the storage object should fill the
79 * whole vector with that value. The length of the vector must be fixed.
80 * The default length is 3 elements.

86 efNoDefaultValue = 1<<7,
88 * Storage object does its custom checking for minimum value count.
90 * If this flag is set, the class derived from OptionStorageTemplate should
91 * implement processSetValues(), processAll(), and possible other functions
92 * it provides such that it always fails if not enough values are provided.
93 * This is useful to override the default check, which is done in
94 * OptionStorageTemplate::processSet().
