Constructor & Destructor Documentation

◆ Application()

AzFramework::Application::Application ( int *  argc,
char ***  argv 
)

recommended: supply &argc and &argv from void main(...) here.

You can pass your command line parameters from main here so that they are thus available in GetCommandLine later, and can be retrieved. see notes in GetArgC() and GetArgV() for details about the arguments.

Member Function Documentation

◆ SetFileIOAliases()

void AzFramework::Application::SetFileIOAliases ( )
protected

set the LocalFileIO and ArchiveFileIO instances file aliases if the FileIOBase environment variable is pointing to the instances owned by the application

◆ Start()

virtual void AzFramework::Application::Start ( const Descriptor &  descriptor,
const StartupParameters &  startupParameters = StartupParameters() 
)
virtual

Executes the AZ:ComponentApplication::Create method and initializes Application constructs. Uses a variant to maintain backwards compatibility with both the Start(const Descriptor& descriptor, const StartupParamters&) and the Start(const char* descriptorFile, const StaartupParameters&) overloads

◆ StartCommon()

virtual void AzFramework::Application::StartCommon ( AZ::Entity *  systemEntity)
protectedvirtual

Called by Start method. Override to add custom startup logic.

◆ Stop()

virtual void AzFramework::Application::Stop ( )
virtual

Executes AZ::ComponentApplication::Destroy, and shuts down Application specific constructs.
