Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

◆ PrintSelf()

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

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ SerializeJSON()

nlohmann::json vtkSerializer::SerializeJSON ( vtkObjectBase * objectBase )

Serialize the VTK object.

◆ RegisterHandler()

void vtkSerializer::RegisterHandler	(	const std::type_info &	type,
		HandlerType	handler
	)

The handlers are invoked to serialize an object of type type.

Note: If type does not have a handler, the serializer will print a stack trace to help you understand the reason for failure.

◆ GetHandler()

HandlerType vtkSerializer::GetHandler ( const std::type_info & type ) const

The handlers are invoked to serialize an object of type type.

Note: If type does not have a handler, the serializer will print a stack trace to help you understand the reason for failure.

◆ UnRegisterHandler()

bool vtkSerializer::UnRegisterHandler ( const std::type_info & type )

The handlers are invoked to serialize an object of type type.

Note: If type does not have a handler, the serializer will print a stack trace to help you understand the reason for failure.

◆ vtkSetSmartPointerMacro()

vtkSerializer::vtkSetSmartPointerMacro	(	Context	,
		vtkMarshalContext
	)

Get/Set the marshalling context.

The vtkSerializer does not track state of any object. However, it leverages the context to prevent re-serialization when there are circular dependencies among VTK objects. The context does much more than just preventing recursive serialization. The serializer records parent-child relationships in the context using it's ScopedParentTracker API.

◆ vtkGetSmartPointerMacro()

vtkSerializer::vtkGetSmartPointerMacro	(	Context	,
		vtkMarshalContext
	)

Get/Set the marshalling context.

The vtkSerializer does not track state of any object. However, it leverages the context to prevent re-serialization when there are circular dependencies among VTK objects. The context does much more than just preventing recursive serialization. The serializer records parent-child relationships in the context using it's ScopedParentTracker API.

◆ SetSerializerLogVerbosity()

void vtkSerializer::SetSerializerLogVerbosity ( vtkLogger::Verbosity verbosity )

Set/Get the log verbosity of messages that are emitted when data is uploaded to GPU memory.

The GetSerializerLogVerbosity looks up system environment for VTK_SERIALIZER_LOG_VERBOSITY that shall be used to set initial logger verbosity. The default value is TRACE.

Accepted string values are OFF, ERROR, WARNING, INFO, TRACE, MAX, INVALID or ASCII representation for an integer in the range [-9,9].

Note: This method internally uses vtkLogger::ConvertToVerbosity(const char*) to parse the value from environment variable.

◆ GetSerializerLogVerbosity()

vtkLogger::Verbosity vtkSerializer::GetSerializerLogVerbosity ( )

Set/Get the log verbosity of messages that are emitted when data is uploaded to GPU memory.

The GetSerializerLogVerbosity looks up system environment for VTK_SERIALIZER_LOG_VERBOSITY that shall be used to set initial logger verbosity. The default value is TRACE.

Accepted string values are OFF, ERROR, WARNING, INFO, TRACE, MAX, INVALID or ASCII representation for an integer in the range [-9,9].
