Function Documentation

coordsetAxes()

std::vector<std::string> axom::bump::utilities::coordsetAxes

(

const conduit::Node &

n_input

)

Return the names of the axes for a coordset.

Parameters

n_input

A Conduit node containing a coordset.

Returns

A vector containing the names of the coordset's axes.

make_array_view() [1/2]

template<typename T >

axom::ArrayView<T> axom::bump::utilities::make_array_view ( conduit::Node &  n )

inline

Make an axom::ArrayView from a Conduit node.

Template Parameters

T	The type for the array view elements.

Parameters

n	The conduit node for which we want an array view.

Returns

An axom::ArrayView that wraps the data in the Conduit node.

make_array_view() [2/2]

template<typename T >

axom::ArrayView<T> axom::bump::utilities::make_array_view ( const conduit::Node &  n )

inline

isDeviceAllocated()

bool axom::bump::utilities::isDeviceAllocated

(

const conduit::Node &

n

)

Returns whether the data pointer in the Conduit node appears to be allocated on a device.

Parameters

n	The node whose data we're checking for device allocation.

Returns

True if the data looks device-allocated; false otherwise.

copy()

template<typename ExecSpace >

void axom::bump::utilities::copy	(	conduit::Node &	dest,
		const conduit::Node &	src,
		int	destAllocatorID = axom::execution_space<ExecSpace>::allocatorID()
	)

Copies a Conduit tree in the src node to a new Conduit dest node, making sure to allocate array data in the appropriate memory space for the execution space.

Template Parameters

ExecSpace

The destination execution space (e.g. axom::SEQ_EXEC).

Parameters

dest	The conduit node that will receive the copied data.
src	The source data to be copied.
destAllocatorID	The allocator for the destination. It defaults to the allocator for ExecSpace.

References axom::isDeviceAllocator().

fillFromNode()

template<typename ArrayType >

bool axom::bump::utilities::fillFromNode	(	const conduit::Node &	n,
		const std::string &	key,
		ArrayType &	arr,
		bool	moveToHost = false
	)

Fill an array with int values from a Conduit node.

Template Parameters

ArrayType

The array type being filled. It must supply size(), operator[].

Parameters

	n	The node that contains the data.
	key	The name of the node that contains the data in n.
[out]	arr	The array being filled.
	moveToHost	Sometimes data are on device and need to be moved to host first.
