arrayToXSData(cls, _array, _bIncludeMd5sum=True, _bForceNoNumpy=False, _bUseAsserts=False)
Class Method

source code 

convert a numpy array or a list of list into an XSDataArray object

Parameters:
  • _array - numpy array or array-like list
  • _bIncludeMd5sum - should the md5sum be added to the XSDataArray instance. It is useful when sending object through the network It is a problem for testing
  • _bForceNoNumpy - enables tests without numpy
  • includeMd5sum (boolean)
Returns:
XSDataArray instance

xsDataToArray(cls, _xsdata, _bCheckMd5sum=True, _bForceNoNumpy=False, _bUseAsserts=False)
Class Method

source code 

convert a XSDataArray into either a numpy array or a list of list

Parameters:
  • _xsdata - XSDataArray instance
  • checkMd5sum - Check if the data are correct based on the checksum It is useful when sending object through the network It is a problem for testing
  • _bForceNoNumpy (boolean) - enables tests without numpy
  • _bCheckMd5sum (boolean)
Returns:
numpy array or array-like list depending on what is available on the computer

getArray(cls, _inputObject)
Class Method

source code 

Tries to retrieve a numpy array from an Image or from a shared array or an XSD object

As this method returns a numpy array, this method works only on plateform where numpy is available.

Parameters:
  • _inputObject - XSDataArray or XSDataImageExt or XSDataFile
Returns:
numpy ndarray
