1 Description

2 Variables

2.1Public Variables

$\mathbf{default\_to\_col\_major}$ – bool Scalar

If true then the default storage order is assumed to be column-major order, otherwise it is assumed to be row-major order. This value is only used if either:

1. (a) None of the data container arguments have implemented the is_col_major method, or
2. (b) The function in question has a multi-dimensional array in a callback function, but no multi-dimensional array in the main function interface.

This defaults to true.

$\mathbf{fail}$ – ErrorHandler Scalar

Error handling class. By default the error handling behaviour is controlled by GLOBAL_ERROR_HANDLER_CONTROL.

$\mathbf{iomanager}$ – IOManagerBase Scalar

Input/Output management class. By default this is set to GLOBAL_IOMANAGER.
