compressionLevelint

Notes

XMLStorageManager enables to read and write OPENTURNS’ objects from a XML file.

Examples

>>> import openturns as ot
>>> # Create a study:
>>> myStudy = ot.Study()
>>> myStudy.setStorageManager(ot.XMLStorageManager('myStudy.xml'))  
>>> myStudy2 = ot.Study()  
>>> myStudy2.setStorageManager(ot.XMLStorageManager('myStudy2.xml.gz', 5))  
>>> # Add an object in the study:
>>> simulationResult = ot.ProbabilitySimulationResult(ot.ThresholdEvent(), 0.5, 0.01, 150, 4)  
>>> myStudy.add('simulationResult', simulationResult)  
>>> # Save the Study in the file myStudy.xml:
>>> myStudy.save()
