virtual void ShallowCopy(vtkInformation *from, vtkInformation *to)=0
Copy the entry associated with this key from one information object to another.
Store vtkAlgorithm input/output information.
static vtkInformationDoubleKey * MakeKey(const char *name, const char *location)
This method simply returns a new vtkInformationDoubleKey, given a name and a location.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void Print(vtkInformation *info)
Print the key's value in an information object to a stream.
Superclass for vtkInformation keys.
a simple class to control print indentation
