Detailed Description

Base class of all labeled and named objects.

Constructor & Destructor Documentation

ConfigObject() [1/2]

ConfigObject::ConfigObject ( QObject *  parent = nullptr )

protected

Specifies the prefix for every ID assigned to every object during serialization.

Hidden constructor.

Parameters

parent

Specifies the QObject parent.

ConfigObject() [2/2]

ConfigObject::ConfigObject ( const QString &  name, QObject *  parent = nullptr  )

protected

Hidden constructor.

Parameters

name	Name of the object.
parent	Specifies the QObject parent.

Member Function Documentation

label()

bool ConfigObject::label ( ConfigObject::Context &  context, const ErrorStack &  err = ErrorStack()  )

virtual

Recursively labels the config object.

Does not assign a label if the idBase passed to the constructor is empty.

Reimplemented from ConfigItem.

parse()

bool ConfigObject::parse ( const YAML::Node &  node, Context &  ctx, const ErrorStack &  err = ErrorStack()  )

virtual

Parses the given YAML node, updates the given object and updates the given context (IDs).

Todo:

With Qt 5.15, we can use the REQUIRED flag to check for mandatory properties. However, Ubuntu 20.04 (Focal) comes with Qt 5.12.

Reimplemented from ConfigItem.

Reimplemented in APRSSystem, PositioningSystem, AESEncryptionKey, DMREncryptionKey, Contact, RoamingChannel, and DMRRadioID.

populate()

bool ConfigObject::populate ( YAML::Node &  node, const Context &  context, const ErrorStack &  err = ErrorStack()  )

protectedvirtual

Recursively serializes the configuration to YAML nodes.

The complete configuration must be labeled first.

Reimplemented from ConfigItem.

Reimplemented in APRSSystem, FMChannel, Channel, RoamingZone, RoamingChannel, and PositioningSystem.
