This factory aims to create an empty DataFrame view.
Columns and rows can be added later.

This factory is aimed at creating a DataFrame view.
- Parameters
-
| shape | shape of the allocated dataframe (column count, row count) |
| columnNames | Array which contains the name for each column |
| columnDataTypes | Array which contains the data type of each column |
- Returns
- an in-memory DataFrameView
- Warning
- No check is done on inputs. Pass arguments very carefully. columnNames and columnDataTypes shall have the same element count, and their size must be equal to shape[0].
-
column count and row count cannot be 0. To create an empty dataframe, use the parameterless allocate method.
