Description

template<typename EnumType>
class gmx::LegacyEnumOption< EnumType >

Specifies an option that accepts enumerated string values and writes the selected index into an enum variable.

Template Parameters

EnumType Type of the variable that receives the values (can also be int).

Examples:

  enum MyEnum { eAtom, eRes, eMol };
  using gmx::LegacyEnumOption;
  const char * const  allowed[] = { "atom", "residue", "molecule" };
  MyEnum       value = eAtom; // default value
  options.addOption(LegacyEnumOption<MyEnum>("type").enumValue(allowed).store(&value));
* 

Works exactly as EnumOption.

This is legacy support for pargsToOptions and can be removed when it is removed. No new uses of it should be made.

Public methods in this class do not throw.

Member Function Documentation

template<typename EnumType >

template<size_t count>

LegacyEnumOption& gmx::LegacyEnumOption< EnumType >::enumValue ( const char *const (&) values[count] )

inline

Sets the option to only accept one of a fixed set of strings.

Parameters

[in] values Array of strings to accept.

Also accepts prefixes of the strings; if a prefix matches more than one of the possible strings, the shortest one is used (in a tie, the first one is).

The strings are copied once the option is created.

template<typename EnumType >

LegacyEnumOption& gmx::LegacyEnumOption< EnumType >::enumValueFromNullTerminatedArray ( const char *const * values )

inline

Sets the option to only accept one of a fixed set of strings.

Parameters

[in] values Array of strings to accept, with a NULL pointer following the last string.

Works otherwise as the array version, but accepts a pointer to an array of undetermined length. The end of the array is indicated by a NULL pointer in the array.
