Returns whether the given dense column is in default state.
- Parameters
-
column | The dense column to be tested for its default state. |
- Returns
- true in case the given dense column is component-wise zero, false otherwise.
This function checks whether the dense column is in default state. For instance, in case the column is instantiated for a built-in integral or floating point data type, the function returns true in case all column elements are 0 and false in case any column element is not 0. The following example demonstrates the use of the isDefault function:
