Member Function Documentation

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::defaultValue ( const int64_t &  defaultValue)
inlineinherited

Sets a default value for the option.

Parameters
[in]defaultValueDefault value.

If the option is never set, the default value is copied to the assigned storage. Note that if the option is not set and there is no default value, the storage is not altered, which can also be used to provide a default value. The latter method has to be used if the option can take multiple values.

defaultValue is copied when the option is created.

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::defaultValueIfSet ( const int64_t &  defaultValue)
inlineinherited

Sets a default value for the option when it is set.

Parameters
[in]defaultValueDefault value.

This value is used if the option is set, but no value is provided. If the option is never set, the value set with defaultValue() is used. Can only be used for options that accept a single value.

defaultValue is copied when the option is created.

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::description ( const char *  descr)
inlineinherited

Sets a description for the option.

Parameters
[in]descrDescription to set.

String in descr is copied when the option is created.

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::required ( bool  bRequired = true)
inlineinherited

Requires the option to be specified explicitly.

Note that if you specify defaultValue() together with required(), the user is not required to explicitly provide the option. In this case, required() only affects possible help output.

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::store ( int64_t *  store)
inlineinherited

Stores value(s) in memory pointed by store.

Parameters
[in]storeStorage for option value(s).

The caller is responsible for allocating enough memory such that the any allowed number of values fits into the array pointed by store. If there is no maximum allowed number or if the maximum is inconveniently large, storeVector() should be used.

For information on when values are available in the storage, see storeVector().

The pointer provided should remain valid as long as the associated Options object exists.

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::storeCount ( int *  countptr)
inlineinherited

Stores number of values in the value pointed by countptr.

Parameters
[in]countptrStorage for the number of values.

For information on when values are available in the storage, see storeVector().

The pointers provided should remain valid as long as the associated Options object exists.

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::storeIsSet ( bool *  store)
inlineinherited

Stores whether the option was explicitly set.

Parameters
[in]storeVariable to store the flag in.

The value is set to false on creation of the option, and to true as soon as a value is assigned to the option. A default value does not set the flag to true, but assignment that uses defaultValueIfSet() does.

The pointer provided should remain valid as long as the associated Options object exists.

MyClass& gmx::OptionTemplate< int64_t , Int64Option >::storeVector ( std::vector< int64_t > *  store)
inlineinherited

Stores option values in the provided vector.

Parameters
[in]storeVector to store option values in.

Values are added to the vector after each successful set of values is parsed. Note that for some options, the value may be changed later, and is only guaranteed to be correct after Options::finish() has been called.

The pointer provided should remain valid as long as the associated Options object exists.
