Detailed Description

Create and synchronize smtk manager instances on the client and server.

This instance will watch for server connection/disconnection events. When a new server is connected, it will have the server-manager instantiate an smtk::resource::Manager there. When a server is disconnected, it will remove information from the client about that server's resources.

At the moment, all this class does is create a resource manager and expose it. It should eventually deal with synchronization issues as stated above, but SMTK's resource manager doesn't deal with remote resources yet.

Member Function Documentation

◆ getPVResource()

QPointer< pqSMTKResource > pqSMTKBehavior::getPVResource ( const smtk::resource::ResourcePtr & rsrc ) const

Return the pqSMTKResource for a given smtk::resource::ResourcePtr.

Note that this is an O(N) operation (linear in the number of resources loaded across all servers).

◆ importPythonOperationsForModule()

void pqSMTKBehavior::importPythonOperationsForModule	(	const std::string &	moduleName,
		const std::string &	operationName
	)

static

Register operations from the named module after the event loop starts.

ParaView loads plugins (including python plugins) before a server connection is established. This method queues a function to run after the event loop starts to register Python operations to the active server's operation manager.

◆ resourceManagerForServer()

pqSMTKWrapper * pqSMTKBehavior::resourceManagerForServer ( pqServer * server = nullptr ) const

Return the server-side container of counterparts for the managers above.

If server is null, a random server's proxy is chosen. Since most apps connect to a single server, this is usually well-defined.

◆ setPostProcessingMode

bool pqSMTKBehavior::setPostProcessingMode ( bool inPost )

virtualslot

Set whether post-processing mode is enabled (true) or disabled (false; default).

The return value indicates whether the value changed.

◆ visitResourceManagersOnServers()

void pqSMTKBehavior::visitResourceManagersOnServers ( const std::function< bool(pqSMTKWrapper *, pqServer *)> & fn ) const

virtual

Call a visitor function fn on each existing resource manager/server pair.

This method has the same signature as the addedManagerOnServer signal, so you can pass a simple lambda that invokes your class's slot to the signal. This way, you can attach signals to resource managers already in existence in addition to those created after your class's initialization.

If the function returns true, then iteration should terminate.

◆ wrapperProxy()

vtkSMSMTKWrapperProxy * pqSMTKBehavior::wrapperProxy ( pqServer * server = nullptr ) const

Return the server-side container of counterparts for the managers above.

If server is null, a random server's proxy is chosen. Since most apps connect to a single server, this is usually well-defined.
