Constructor & Destructor Documentation

LeafNode ( )
inline

Default constructor.

LeafNode ( const Coord &  xyz,
bool  value = false,
bool  active = false 
)
inlineexplicit

Constructor

Parameters
xyzthe coordinates of a voxel that lies within the node
valuethe initial value for all of this node's voxels
activethe active state to which to initialize all voxels
LeafNode ( PartialCreate  ,
const Coord &  xyz,
bool  value = false,
bool  active = false 
)
inline

"Partial creation" constructor used during file input

LeafNode ( const LeafNode< bool, Log2Dim > &  other)
inline

Deep copy constructor.

LeafNode ( const LeafNode< OtherValueType, Log2Dim > &  other)
explicit

Value conversion copy constructor.

LeafNode ( const LeafNode< ValueType, Log2Dim > &  other,
TopologyCopy   
)

Deprecated topology copy constructor.

Note
This constructor initialises the bool buffer to the ValueMask states (i.e. value will be true if the active state is on and vice-versa). This is not really a "TopologyCopy" and is therefor deprecated. Use the explicit mask/buffer constructor instead:
// build new leaf node with the mask of 'a', but with the mask of
// 'b' as the the new value buffer.
const LeafNode a = ... ;
const LeafNode b = ... ;
const LeafNode copy(a.origin(), /*mask=*/a.getValueMask(),
/*buff=*/b.getValueMask());
Deprecated:
"Use LeafNodeBool component constructor."
LeafNode ( const Coord &  xyz,
const NodeMaskType mask,
const Buffer buff,
const Index32  trans = 0 
)
inline

Construct a LeafNodeBool with its individual components.

Parameters

maskThe ValueMask to copy
buffThe LeafBuffer to copy (also constructable from a ValueMask)
transTransient data (ignored until ABI 9)
LeafNode ( const LeafNode< ValueType, Log2Dim > &  other,

densedense grid with a stride in z of one (see tools::Dense in tools/Dense.h for the required API)
backgroundbackground value of the tree that this node belongs to
tolerancetolerance within which a value equals the background value
Note
bbox is assumed to be identical to or contained in the coordinate domains of both the dense grid and this node, i.e., no bounds checking is performed.
