DFBoolColumnApply(String, FuncBoolean, Boolean, Boolean, DFBoolColumn) Method

Returns a new column with the given name and same size as this column, whose values are the result of applying the given binary function to each element of this column. The first parameter to the binary function is an element of self; the second parameter is the corresponding element of the passed column.
