Detailed Description

vtkPVSession defines a session i.e.

a conversation, namely, those that are used to communicate between data-server,render-server and client. It can be between different processes or same process. What types of conversations are possible i.e what protocols are supported, is defined by the subclasses. This is an abstract class.

Member Function Documentation

◆ GetClassName()

virtual const char* vtkPVSession::GetClassName ( )

virtual

Reimplemented in vtkPVSessionBase, vtkSMSession, vtkSMSessionClient, and vtkPVSessionServer.

◆ IsTypeOf()

static int vtkPVSession::IsTypeOf ( const char * type )

static

◆ IsA()

virtual int vtkPVSession::IsA ( const char * type )

virtual

Reimplemented from vtkObjectBase.

Reimplemented in vtkPVSessionBase, vtkSMSession, vtkSMSessionClient, and vtkPVSessionServer.

◆ SafeDownCast()

static vtkPVSession* vtkPVSession::SafeDownCast ( vtkObject * o )

static

◆ PrintSelf()

void vtkPVSession::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Reimplemented from vtkObject.

Reimplemented in vtkPVSessionBase, vtkSMSession, vtkSMSessionClient, and vtkPVSessionServer.

◆ GetIsAlive()

virtual bool vtkPVSession::GetIsAlive ( )

pure virtual

Returns true is this session is active/alive/valid.

Implemented in vtkSMSession, vtkSMSessionClient, and vtkPVSessionServer.

◆ GetProcessRoles()

virtual ServerFlags vtkPVSession::GetProcessRoles ( )

virtual

Returns a ServerFlags indicate the nature of the current processes.

e.g. if the current processes acts as a data-server and a render-server, it returns DATA_SERVER | RENDER_SERVER.

Reimplemented in vtkSMSession, vtkSMSessionClient, and vtkPVSessionBase.

◆ HasProcessRole()

bool vtkPVSession::HasProcessRole ( vtkTypeUInt32 flag )

inline

Convenience method that returns true if the current session is serving the indicated role on this process.

Definition at line 59 of file vtkPVSession.h.

◆ GetController()

virtual vtkMultiProcessController* vtkPVSession::GetController ( ServerFlags processType )

virtual

Returns the controller used to communicate with the process.

Value must be DATA_SERVER_ROOT or RENDER_SERVER_ROOT or CLIENT. Default implementation returns nullptr.

Reimplemented in vtkSMSessionClient, and vtkPVSessionServer.

◆ GetMPIMToNSocketConnection()

virtual vtkMPIMToNSocketConnection* vtkPVSession::GetMPIMToNSocketConnection ( )

inlinevirtual

This is socket connection, if any to communicate between the data-server and render-server nodes.

Reimplemented in vtkPVSessionBase.

Definition at line 75 of file vtkPVSession.h.

◆ GetServerInformation()

virtual vtkPVServerInformation* vtkPVSession::GetServerInformation ( )

pure virtual

vtkPVServerInformation is an information-object that provides information about the server processes.

These include server-side capabilities as well as server-side command line arguments e.g. tile-display parameters. Use this method to obtain the server-side information. NOTE: For now, we are not bothering to provide separate information from data-server and render-server (as was the case earlier). We can easily add API for the same if needed.

Implemented in vtkSMSessionClient, and vtkPVSessionBase.

◆ IsMultiClients()

virtual bool vtkPVSession::IsMultiClients ( )

virtual

Allow anyone to know easily if the current session is involved in collaboration or not.

This is mostly true for the Client side.

◆ GetProgressHandler()

virtual vtkPVProgressHandler* vtkPVSession::GetProgressHandler ( )

virtual

Provides access to the progress handler.

◆ PrepareProgress()

void vtkPVSession::PrepareProgress ( )

Should be called to begin/end receiving progresses on this session.

◆ CleanupPendingProgress()

void vtkPVSession::CleanupPendingProgress ( )

Should be called to begin/end receiving progresses on this session.

◆ GetPendingProgress()

bool vtkPVSession::GetPendingProgress ( )

Returns true if the session is within a PrepareProgress() and CleanupPendingProgress() block.

◆ OnWrongTagEvent()

virtual bool vtkPVSession::OnWrongTagEvent	(	vtkObject *	caller,
		unsigned long	eventid,
		void *	calldata
	)

protectedvirtual

Callback when any vtkMultiProcessController subclass fires a WrongTagEvent.

Return true if the event was handle localy.

Reimplemented in vtkSMSessionClient.

◆ PrepareProgressInternal()

virtual void vtkPVSession::PrepareProgressInternal ( )

protectedvirtual

Virtual methods subclasses can override.

Reimplemented in vtkPVSessionBase, and vtkSMSessionClient.

◆ CleanupPendingProgressInternal()

virtual void vtkPVSession::CleanupPendingProgressInternal ( )

protectedvirtual

Virtual methods subclasses can override.

Reimplemented in vtkPVSessionBase, and vtkSMSessionClient.

◆ Activate()

virtual void vtkPVSession::Activate ( )

protectedvirtual

Subclasses must call this to mark the session active.

This sets the active session pointer held by the vtkProcessModule, making it easier for filters etc. that need information about the active session to access it.

◆ DeActivate()

virtual void vtkPVSession::DeActivate ( )

protectedvirtual

Subclasses must call this to mark the session inactive.

This sets the active session pointer held by the vtkProcessModule, making it easier for filters etc. that need information about the active session to access it.
