Detailed Description

This class provide access to the application run-time data including the in-memory DB.

Constructor & Destructor Documentation

DataContext() [1/2]

hlcc::pfssimhlcc::DataContext::DataContext

(

std::shared_ptr< OldbInterface >

oldb_interface = nullptr

)

This constructor uses the application configuration to initialize the adapter object to the in-memory DB.

Parameters

[in]

oldb_interface

Can be passed explicitly to use a mock for testing. Otherwise it will be created.

~DataContext()

hlcc::pfssimhlcc::DataContext::~DataContext ( )

virtual

Destructor

DataContext() [2/2]

hlcc::pfssimhlcc::DataContext::DataContext ( const DataContext & )

delete

Member Function Documentation

EnablePublishing()

void hlcc::pfssimhlcc::DataContext::EnablePublishing

(

bool

enabled

)

Normally methods of DataContext write to the OLDB, or also publish data on channels. This method allows controlling this behavior, e.g. for unit tests.

Parameters

enabled

true enables publishing, false disables it (or also when the MS LSV does the publishing instead???)

GetConfig()

Config & hlcc::pfssimhlcc::DataContext::GetConfig ( )

override

Returns

reference to the Config object.

GetConfigConst()

const Config & hlcc::pfssimhlcc::DataContext::GetConfigConst

(

)

const

Returns

const reference to the Config object. This allows having const methods in DataContext that get config parameters.

GetOldbInterface()

OldbInterface & hlcc::pfssimhlcc::DataContext::GetOldbInterface ( )

override

Returns

A reference to the OLDB interface object.

IsPublishingEnabled()

bool hlcc::pfssimhlcc::DataContext::IsPublishingEnabled

(

)

const

See also

EnablePublishing(bool)

operator=()

DataContext & hlcc::pfssimhlcc::DataContext::operator= ( const DataContext & )

delete

Disable copy constructor.

ReloadConfig()

void hlcc::pfssimhlcc::DataContext::ReloadConfig ( )

override

Reload the configuration from file.

UpdateDb()

void hlcc::pfssimhlcc::DataContext::UpdateDb ( )

override

Try to connect to the DB and write the application configuration to the OLDB.

Initially called by rad::Application::Init. Later also called by, e.g., ActionsApp::SetConfig.

We initialize the telescope position with the value from OLDB, reflecting a previous run. The target pos also gets initialized to the current pos so that the telescope initially stands still.

rad::Application::Init calls only DataContext::UpdateDb, but no other, more suitable, init method of DataContext. Note that in the ctor of DataContext, Config is not yet initialized and thus we cannot use OldbInterface yet.
