Detailed Description

A set of mutable_column_views of the same size.

All public member functions and constructors are inherited from table_view_base<mutable_column_view>.

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_error

If number of rows mismatch

Parameters

views

The 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_index

The index of the desired column

Returns

A mutable column view reference to the desired column
