OptionDecl Class Reference

Description:

A declaration for an cli::Option .

Construction is done by passing a custom enum element of an enum type equipped with ALib Enum Records of type EROptionDecl .

When bootstrapping ALib CLI , method CommandLine::DefineOptions has to be invoked for (each) enum type.

Constructor(s) / Destructor Details::

OptionDecl()

template<typename TEnum >

OptionDecl ( TEnum element )

inline

Templated constructor which takes an enum element of a custom type equipped with ALib Enum Records of type EROptionDecl .

Template Parameters

TEnum

C++ enum type equipped with corresponding ALib Enum Records.

Parameters

element

The enum element

Method Details:

Element()

const Enum & Element ( ) const

inline

Returns the type and integral value of the enumeration element used with construction.

Returns

The enumeration element used with construction.

Definition at line 373 of file arguments.hpp.

HelpText()

const String & HelpText ( )

inline

Returns the help text. Loads the string from resourceInfo using resource name "TOptHlpNN", where NN is the enum element's integral value.

Returns

The help text.

Here is the call graph for this function:

HelpUsageLine()

const String & HelpUsageLine ( )

inline

Returns a formal description of the usage. Loads the string from resourceInfo using resource name "TOptUsgNN", where NN is the enum element's integral value.

Returns

The help text.

Definition at line 442 of file arguments.hpp.

Here is the call graph for this function:

Identifier()

const String & Identifier ( )

inline

Returns the identifier of the option if double hyphen '–' is used.

Returns

The option identifier.

Definition at line 382 of file arguments.hpp.

IdentifierChar()

character IdentifierChar ( )

inline

Returns the identifier of the option if single hyphen '-' is used.

Returns

The option identifier.

Definition at line 400 of file arguments.hpp.

Here is the call graph for this function:

MinimumRecognitionLength()

int MinimumRecognitionLength ( )

inline

Returns the minimum parse length of the identifier if double hyphen '–' is used.

Returns

The minimum characters to satisfy the option.

Definition at line 391 of file arguments.hpp.

QtyExpectedArgsFollowing()

integer QtyExpectedArgsFollowing ( )

inline

The number of CLI arguments to consume and store in Option::Args with method Option::Read .

Returns

The option identifier.

Definition at line 421 of file arguments.hpp.

ShortcutReplacementString()

const String & ShortcutReplacementString ( )

inline

If an option is a shortcut to another one, this string replaces the argument given.

Returns

The option identifier.

Definition at line 430 of file arguments.hpp.

ValueSeparator()

const String & ValueSeparator ( )

inline
