Method Details:

◆ Read()

bool alib::app::Parameter::Read ( ParameterDecl & decl )

Tries to read the object from the front of StdVectorMA< integer > ArgsLeft. Success is indicated by setting inherited fields integer Position and integer ConsumedArguments to values greater than 0.

If it could not be decided if the actual CLI argument contains this parameter, false is returned to indicate that parsing commands has to stop now.

This is done in the following cases:

When const String & Identifier() is empty and the parameter is bool IsOptional() gives true.
When it was successfully read, but int QtyExpectedArgsFollowing() is defined -1.
