Detailed Description

The WorkspaceManager is responsible for clearing, loading, and saving a workspace. Different items such as the processor network can register callbacks for clearing, loading, or saving a workspace. Other object can also register callbacks. It also responsible for keeping a list of factories to use while deserializing. Other module can register factories that should be used while deserializing. The user interface should use the Workspace Manager to clear, load, and save workspaces. instead of calling the Processor Network directly. The workspace manager is owned by the InviwoApplication.

Member Function Documentation

clear()

void inviwo::WorkspaceManager::clear

(

)

Clear the current workspace. This will invoke all the clear callback that have been added.

createWorkspaceDeserializer()

Deserializer inviwo::WorkspaceManager::createWorkspaceDeserializer	(	std::istream &	stream,
		const std::string &	refPath,
		Logger *	logger = LogCentral::getPtr()
	)		const

Create a deserializer for a workspace stream, and apply all needed version updates.

load() [1/2]

void inviwo::WorkspaceManager::load	(	std::istream &	stream,
		const std::string &	refPath,
		const ExceptionHandler &	exceptionHandler = StandardExceptionHandler()
	)

Load a workspace from a stream

Parameters

stream	the stream to read from.
refPath	a reference that that can be use by the deserializer to calculate relative paths. The same refPath should be given when loading. Most often this should be the path to the saved file.
exceptionHandler	A callback for handling errors.

load() [2/2]

void inviwo::WorkspaceManager::load	(	const std::string &	path,
		const ExceptionHandler &	exceptionHandler = StandardExceptionHandler()
	)

Load a workspace from a file

Parameters

path	the file to read from.
exceptionHandler	A callback for handling errors.

onClear()

WorkspaceManager::ClearHandle inviwo::WorkspaceManager::onClear

(

const ClearCallback &

callback

)

Callback for clearing the workspace.

onLoad()

WorkspaceManager::DeserializationHandle inviwo::WorkspaceManager::onLoad

(

const DeserializationCallback &

callback

)

Callback for loading the workspace.

onSave()

WorkspaceManager::SerializationHandle inviwo::WorkspaceManager::onSave	(	const SerializationCallback &	callback,
		WorkspaceSaveModes	modes = WorkspaceSaveModes{flags::any}
	)

Callback for saving the workspace.

registerFactory()

void inviwo::WorkspaceManager::registerFactory

(

FactoryBase *

factory

)

Register a factory that should be used by the workspace loading to create items.

save() [1/2]

void inviwo::WorkspaceManager::save	(	std::ostream &	stream,
		const std::string &	refPath,
		const ExceptionHandler &	exceptionHandler = StandardExceptionHandler(),
		WorkspaceSaveMode	mode = WorkspaceSaveMode::Disk
	)

Save the current workspace to a stream

Parameters

stream	the stream to write to.
refPath	a reference that that can be use by the serializer to store relative paths. The same refPath should be given when loading. Most often this should be the path to the saved file.
exceptionHandler	A callback for handling errors.
mode	to indicate if we are saving to disk or undo-stack

save() [2/2]

void inviwo::WorkspaceManager::save	(	const std::string &	path,
		const ExceptionHandler &	exceptionHandler = StandardExceptionHandler(),
		WorkspaceSaveMode	mode = WorkspaceSaveMode::Disk
	)

Save the current workspace to a file

Parameters

path	the file to save into.
exceptionHandler	A callback for handling errors.
mode	to indicate if we are saving to disk or undo-stack
