Member Function Documentation

CDPBaseObject::CDPBaseObject()

Constructs the CDPBaseObject, initializing members to correct defaults.

[default] CDPBaseObject::CDPBaseObject(CDPBaseObject &&other)

Move-copy constructor.

CDPBaseObject::~CDPBaseObject()

Destructs the object.

[virtual] void CDPBaseObject::Activate()

Causes the object to be activated so it can receive messages.

This function is typically called by the CDP Framework, or from a derived class's Activate function. When this function is called, the member mutex of the CDPComponent (if this is not a CDPComponent: then the member mutex of the object owner) has already been locked. Activate() may be called from another thread, typically the main thread or the Application process thread, or from the correct CDPEngine scheduler.

[virtual] bool CDPBaseObject::Activated() const

Returns true if object is activated.

void CDPBaseObject::AddToCDPEngine()

Registers itself in CDPEngine in order to be able to receive messages.

[virtual] void CDPBaseObject::ClockIn()

Performs consistent state update of inputs.

[virtual] void CDPBaseObject::ClockOut()

Performs consistent state update of outputs.

[virtual] void CDPBaseObject::Configure(XMLPrimitive *pObjectXML)

Configures this object from the XML tree provided.

[virtual] void CDPBaseObject::Create(const char *shortName, CDPBaseObject *pParentObject)

Creates the object, names it and gives it a parent (Note: Parent can be nullptr)

This function must be called from the derived class' Create() implementation. If this CDPBaseObject is not CDPObject based, the Create() function will add the object to m_listBaseObject in the parent (CDPObject) if parent is not nullptr.

[virtual] void CDPBaseObject::CreateModel()

Creates the model named pzModel and registers the SetProperty and GetProperty message-handlers.

[virtual] void CDPBaseObject::Destroy()

Destroys the object.

[override virtual] void CDPBaseObject::FillNodeChildren(CDP::StudioAPI::NodeStream &stream) const

Reimplemented from CDPNode::FillNodeChildren().

Serializes shortname, suspended, properties, messages (if object is able to receive messages) and nodelist.

[override virtual] const std::string CDPBaseObject::GetNodeName() const

Reimplemented from ICDPNode::GetNodeName().

Returns the ShortName of this object.

[override virtual] CDP::StudioAPI::CDPNodeType CDPBaseObject::GetNodeType() const

Reimplemented from ICDPNode::GetNodeType().

Returns CDP::StudioAPI::eCDP_BASE_OBJECT_NODE.

[override virtual] std::string CDPBaseObject::GetNodeTypeName() const

Reimplemented from ICDPNode::GetNodeTypeName().

Returns "CDPBaseObject".

[virtual] CDPBaseObject *CDPBaseObject::GetOwner() const

CDPComponent *CDPBaseObject::GetParent() const

Returns the parent CDPComponent, or nullptr if 'this' is a CDPCompoent.

[virtual] std::string CDPBaseObject::GetProperty(std::string propertyName)

Gets the value of propertyName. Example:

std::string strUnit = signal.GetProperty("Unit");

The returned string is empty if there is no property with propertyName.

[virtual] const CDPPropDB &CDPBaseObject::GetPropertyList() const

Returns the property database.

[virtual] CDPPropertyBase *CDPBaseObject::GetPropertyObject(std::string propertyName) const

Returns the pointer to the named property object, or nullptr if not found. Example:

CDPPropertyBase* pUnit= signal.GetPropertyObject("Unit");
if(pUnit!=nullptr)
  pUnit->SetPropertyChangeHandler([this](CDPPropertyBase*){ CDPMessage("Unit changed!\n"); });

[static] const char *CDPBaseObject::GetTemplateSubTypeInfo(const char *pzSubTypeInfo)

Returns the template part of pzSubTypeInfo.

This function can be called from a template<T> class like this:

string typeName = GetTemplateSubTypeInfo(typeid(T).name());

The returned string would then contain the type (int, double, etc) of the class.

[virtual] std::string CDPBaseObject::GetTypeIdName() const

Gets the model name derived from the compiler dependent TypeId.

[virtual] unsigned int CDPBaseObject::Handle() const

Returns the complete 32 bit handle for this object (appHandle:object).

The unique Handle is typically not used for CDPBaseObjects, but some operators, like AlarmOperator, uses it.

[virtual] bool CDPBaseObject::IsComponent() const

Returns true if this object is of type CDPComponent.

[virtual] bool CDPBaseObject::IsSystemMessage(Message *message) const

Returns true if message is a message that should be processed even if suspended.

[virtual] int CDPBaseObject::MessageGetProperty(void *message)

Responds with a MessageCDPMessage with the property=value.

This function can be invoked by doing SendMessage(msg,true) so a MessageACK packet is returned to sender. This function expects to receive a MessageTextCommandWithParameterSend where the field 'textCommand' is set to 'GetProperty' (without the quotes) and the field 'parameters' is set to the name of the property to retrieve. This function will modify the message to contain 'propertyName=propertyValue' (without the quotes). The max length of the returned string in the message is capped at 1000 bytes including nullterminator.

See also CDPBaseObject::GetProperty.

[virtual] int CDPBaseObject::MessageSetProperty(void *message)

Sets a property in the object by decoding message and calling SetProperty(propertyName,propertyValue) Expects that message is sent as a MessageTextCommandWithParameterSend, where the field 'textCommand' is set to nullterminated string value 'SetProperty' (without the quotes), and the field 'parameters' is set to nullterminated string containing 'propertyName=propertyValue' (without the quotes).

Optionally the form 'propertyName=propertyValue;Save=0' (or ...Save=1) may be used. Then the SaveOnChange setting of the CDPProperty is ignored and the parameter of the message is temporarily used instead.

If either propertyName or propertyValue contains special characters, they must be surrounded with single or double quotes ("propertyName"="property;Value";Save=1). Quotes inside values must always be escaped using backslash (propertyName=Quotes\'In\"Value).

See also CDPBaseObject::SetProperty and CDPConnector::SetProperty.

[virtual] int CDPBaseObject::ReceiveMessage(void *message)

Forwards the message to the correct messagehandler.

int CDPBaseObject::RecvMessage(void *message)

Handles message reception, with notification to StudioAPI.

[virtual] void CDPBaseObject::RegisterCDPNode(CDP::StudioAPI::CDPNode *pCDPNode)

Adds pCDPNode to m_CDPNodeList.

m_CDPNodeList is serialized in FillNodeChildren().

[virtual] void CDPBaseObject::RegisterMessage(int command, const char *textCommand, const char *description, CDPOBJECT_MESSAGEHANDLER messageHandler = nullptr, const char *parameterName = nullptr, CDP::StudioAPI::CDPNodeModeFlags flags = {})

Registers message with description and message handler. Example:

void MyDerived::CreateModel(const char* pzModel)
{
  CDPBaseObject::CreateModel(pzModel);
  ...
  RegisterMessage(CM_TEXTCOMMAND,"MySpecialMessage","MySpecialMesssage handler",(CDPOBJECT_MESSAGEHANDLER)&MySpecialObject::MessageMySpecialMessageHandler);
}

The above code registers a message 'MySpecialMessage' into MySpecialObject. Note that the Model .xml file for the object must also be updated for the message to be visible in CDP Studio :

<Messages>
  <Message Command="CM_TEXTCOMMAND" Name="MySpecialMessage" Description="MySpecialMesssage handler"></Message>
</Messages>

[virtual] void CDPBaseObject::RegisterMessage(int command, const char *textCommand, const char *description, const std::function<int( void * ) > &messageHandler, const char *parameterName, CDP::StudioAPI::CDPNodeModeFlags flags = {})

Registers message with description and message handler. Example:

void MyDerived::CreateModel(const char* pzModel)
{
  CDPBaseObject::CreateModel(pzModel);
  ...
  RegisterMessage(CM_TEXTCOMMAND,"MySpecialMessage","MySpecialMesssage handler", std::bind(&MySpecialObject::MessageMySpecialMessageHandler, this, std::placeholders::_1));
}

The above code registers a message 'MySpecialMessage' into MySpecialObject. Note that the Model .xml file for the object must also be updated for the message to be visible in CDP Studio :

<Messages>
  <Message Command="CM_TEXTCOMMAND" Name="MySpecialMessage" Description="MySpecialMesssage handler"></Message>
</Messages>

[virtual] void CDPBaseObject::RegisterProperty(CDPPropertyBase *pProp)

Registers pProp in the property database.

void CDPBaseObject::RemoveFromCDPEngine()

Deregisters itself from CDPEngine

void CDPBaseObject::RemoveMessage(int command)

Removes a previously registered message identified by command.

void CDPBaseObject::RemoveMessage(const char *textCommand)

Removes a previously registered message identified by textCommand.

void CDPBaseObject::SendNotify(MessageRequestHandle *message) const

Sends a CM_NOTIFY message back to the origin of message.

The notify message is used to notify the existence of an object. The requesting object uses the notify reply to determine the existence and handle of an object.

Uses the origin of message as destination for notify message.

[virtual] unsigned int CDPBaseObject::SetHandle(unsigned int handle)

Sets the object part of the handle for this CDPObject.

Returns the full 32 bit handle.

[virtual] void CDPBaseObject::SetProperty(std::string propertyName, std::string propertyValue)

Sets propertyName in the object to propertyValue. Example:

object.SetProperty("Unit","m/s");

If there is no property named propertyName then an error-message will be printed and the property will not be set.

[virtual] void CDPBaseObject::SetTypeIdName(const std::string &strPromotedModelName)

Sets the TypeId name to strPromotedModelName.

[virtual] const char *CDPBaseObject::ShortName() const

Returns the "short" name of the object (relative to the parent object).

[virtual] unsigned int CDPBaseObject::Status() const

Returns a status according to Alarm Status Defines.

This base implementation returns STATUS_OK.

[virtual] void CDPBaseObject::Suspend()

Causes the object to be suspended.

This function is typically called by the CDP Framework, or from a derived class's Suspend function. Calling it stops the message processing. The member mutex of the Component or owner object has already been locked when this function is called. Suspend() will be called from the correct CDPEngine scheduler during runtime, or from the main task on shutdown.

[virtual] void CDPBaseObject::UnRegisterCDPNode(CDP::StudioAPI::CDPNode *pCDPNode)

Removes pCDPNode from m_CDPNodeList.

Call this in Destroy() when you have called RegisterCDPNode().

void CDPBaseObject::UnRegisterProperty(CDPPropertyBase *pProp)

Unregisters pProp from the property database.
