◆ DataExpanded() [1/9]

escript::DataExpanded::DataExpanded ( const WrappedArray value,
const FunctionSpace what

explicit

Constructor for DataExpanded.

Description: Constructor for DataExpanded.

The given single data value is copied to all the data points in this data object, where the number of data points is defined by the given function space.

Parameters
value- Input - The value of a single data point.
what- Input - A description of what this data represents.

Alternative constructor for DataExpanded objects.

Description: Alternative Constructor for DataExpanded objects.

Parameters
what- Input - A description of what this data object represents.
shape- Input - the shape of each data-point.
data- the array of data values for the data-points.

TODO Note that this constructor will also copy data to all points if it only contains enough elements to hold a single point. ie this is the merge of two separate constructors.
