CommandDecl Class Reference

Description:

A declaration for a cli::Command .

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

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

Constructor(s) / Destructor Details::

CommandDecl()

template<typename TEnum >

CommandDecl ( TEnum element, CommandLine & cmdLine )

inline

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

Field Parameters is filled as specified in the enum record.

Template Parameters

TEnum

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

Parameters

element	The enum element
cmdLine	The command line object. Will be stored.

Definition at line 594 of file commandline.hpp.

Method Details:

addParamDecls()

void addParamDecls ( )

protected

Called from the constructor. Parses field ERCommandDecl::parameters of the enum record, and loads the corresponding parameters.

Definition at line 38 of file arguments.cpp.

Here is the call graph for this function:

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 573 of file arguments.hpp.

GetParameterDecl()

ParameterDecl * GetParameterDecl

(

const String &

name

)

Searches in Parameters for the declaration of parameter name .

Parameters

name	The declaration name of the parameter.

Returns

A pointer to the parameter's declaration, nullptr if parameter was not declared.

Definition at line 59 of file arguments.cpp.

HelpTextLong()

const String & HelpTextLong ( )

inline

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

Returns

The help text.

Definition at line 613 of file arguments.hpp.

Here is the call graph for this function:

HelpTextShort()

const String & HelpTextShort ( )

inline

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

Returns

The help text.

Definition at line 602 of file arguments.hpp.

Identifier()

const String & Identifier ( )

inline

Returns the identifier (name) of the command

Returns

The command identifier.

Definition at line 582 of file arguments.hpp.

MinimumRecognitionLength()

int MinimumRecognitionLength ( )

inline

Returns the minimum parse length of the identifier.

Returns

The minimum characters to satisfy the command to be parsed.

Definition at line 591 of file arguments.hpp.
