Member Function Documentation

create()

static auto cudf::table_device_view::create ( table_view  source_view, rmm::cuda_stream_view  stream = cudf::get_default_stream()  )

inlinestatic

Factory to construct a table device view that is usable in device memory.

Allocates and copies views of source_view's children to device memory to make them accessible in device code.

Returns a std::unique_ptr<table_device_view> with a custom deleter to free the device memory allocated for the children.

Parameters

source_view	The table view whose contents will be copied to create a new table
stream	CUDA stream used for device memory operations

Returns

A unique_ptr to a table_device_view that makes the data from source_view available in device memory
