Detailed Description

key used to define meta-data of type vtkDataObject vtkInformationDataObjectMetaDataKey is a vtkInformationDataObjectKey that (shallow) copies itself downstream during the REQUEST_INFORMATION pass.

Hence it can be used to provide meta-data of type vtkDataObject or any subclass.

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 vtkInformationDataObjectKey.

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 vtkInformationDataObjectKey.

◆ MakeKey()

static vtkInformationDataObjectMetaDataKey * vtkInformationDataObjectMetaDataKey::MakeKey	(	const char *	name,
		const char *	location
	)

inlinestatic

This method simply returns a new vtkInformationDataObjectMetaDataKey, given a name and a location.

This method is provided for wrappers. Use the constructor directly from C++ instead.

Definition at line 38 of file vtkInformationDataObjectMetaDataKey.h.

◆ CopyDefaultInformation()

void vtkInformationDataObjectMetaDataKey::CopyDefaultInformation	(	vtkInformation *	request,
		vtkInformation *	fromInfo,
		vtkInformation *	toInfo
	)

override

Simply shallow copies the key from fromInfo to toInfo if request has the REQUEST_INFORMATION() key.

This is used by the pipeline to propagate this key downstream.
