`vtkmodules.util.information`#

Pythonic interfaces for vtkInformation and vtkInformationVector.

Makes vtkInformation behave like a Python dictionary (key -> value)::

from vtkmodules.vtkCommonDataModel import vtkDataObject
info = vtkInformation()
info[vtkDataObject.FIELD_NAME()] = "Pressure"
info[vtkDataObject.FIELD_NAME()]           # "Pressure"
vtkDataObject.FIELD_NAME() in info         # True
del info[vtkDataObject.FIELD_NAME()]       # Remove entry
len(info)                                  # entry count
for key in info: ...                       # iterate vtkInformationKey objects
info.keys()                                # list of vtkInformationKey objects
info.string_keys()                         # list of key name strings
info.values(), info.items()                # dict-like views

Makes vtkInformationVector behave like a Python list::

vec = vtkInformationVector()
vec.append(vtkInformation())
len(vec)          # 1
vec[0]            # vtkInformation
for info in vec:  # iterate
