Constructor & Destructor Documentation

◆ mutable_table_view()

cudf::mutable_table_view::mutable_table_view ( std::vector< mutable_table_view > const &  views)

Construct a table from a vector of table views.

Note
Because a std::vector is constructible from a std::initializer_list, this constructor also supports the following usage:
table_view t0, t1, t2;
...
table_view t{{t0,t1,t2}}; // Creates a `table` from the columns of
t0, t1, t2
Exceptions
cudf::logic_errorIf number of rows mismatch
Parameters
viewsThe vector of table views to construct the table from

Member Function Documentation

◆ column()

mutable_column_view& cudf::mutable_table_view::column ( size_type  column_index) const
inline

Returns column at specified index.

Parameters
column_indexThe index of the desired column
Returns
A mutable column view reference to the desired column
