Member Function Documentation

MyClass& gmx::OptionTemplate< gmx_int64_t , Int64Option >::defaultValue ( const gmx_int64_t & defaultValue )

inlineinherited

Sets a default value for the option.

Parameters

[in] defaultValue Default 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< gmx_int64_t , Int64Option >::defaultValueIfSet ( const gmx_int64_t & defaultValue )

inlineinherited

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

Parameters

[in] defaultValue Default 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< gmx_int64_t , Int64Option >::description ( const char * descr )

inlineinherited

Sets a description for the option.

Parameters

[in] descr Description to set.

String in descr is copied when the option is created.

MyClass& gmx::OptionTemplate< gmx_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.

void gmx::AbstractOption::setVector ( )

inlineprotectedinherited

Sets the option to be vector-valued.

This method is provided for convenience to make management of value counts easier. In order to implement a vector-valued option, the class derived from AbstractOption should expose a method that calls this method, and the storage object derived from AbstractOptionStorage should check isVector(). If only a single value is provided, the storage object should fill the whole vector with that value.

The length of the vector (the value of maxValueCount_) must be fixed. The default length is 3 elements.

MyClass& gmx::OptionTemplate< gmx_int64_t , Int64Option >::store ( gmx_int64_t * store )

inlineinherited

Stores value(s) in memory pointed by store.

Parameters

[in] store Storage 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< gmx_int64_t , Int64Option >::storeCount ( int * countptr )

inlineinherited

Stores number of values in the value pointed by countptr.

Parameters

[in] countptr Storage 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< gmx_int64_t , Int64Option >::storeIsSet ( bool * store )

inlineinherited

Stores whether the option was explicitly set.

Parameters

[in] store Variable 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< gmx_int64_t , Int64Option >::storeVector ( std::vector< gmx_int64_t > * store )

inlineinherited

Stores option values in the provided vector.

Parameters

[in] store Vector 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.
