51 /*! \libinternal \brief
54 * These flags are not part of the public interface, even though they are in an
55 * installed header. They are needed in a few template class implementations.
59 //! %Option has been set.
61 //! The current value of the option is a programmatic default value.
62 efHasDefaultValue = 1<<1,
64 * Next assignment to the option clears old values.
66 * This flag is set when a new option source starts, such that values
67 * from the new source will overwrite old ones.
69 efClearOnNextSet = 1<<5,
70 //! %Option is required to be set.
72 //! %Option can be specified multiple times.
74 //! %Option is hidden from standard help.
77 * %Option value is a vector, but a single value is also accepted.
79 * If only a single value is provided, the storage object should fill the
80 * whole vector with that value. The length of the vector must be fixed.
81 * The default length is 3 elements.
84 efExternalStore = 1<<8,
85 efExternalValueVector = 1<<10,
86 //! %Option does not support default values.
87 efNoDefaultValue = 1<<7,
89 * Storage object does its custom checking for minimum value count.
91 * If this flag is set, the class derived from OptionStorageTemplate should
92 * implement processSetValues(), processAll(), and possible other functions
93 * it provides such that it always fails if not enough values are provided.
94 * This is useful to override the default check, which is done in
95 * OptionStorageTemplate::processSet().
97 efDontCheckMinimumCount = 1<<16,
101 //efStaticEnum = 1<<19,
106 //! \libinternal Holds a combination of ::OptionFlag values.
