Classes

struct  ChildIter
 Leaf nodes have no children, so their child iterators have no get/set accessors. More...
 
struct  DenseIter
 
struct  SameConfiguration
 SameConfiguration<OtherNodeType>::value is true if and only if OtherNodeType is the type of a LeafNode with the same dimensions as this node. More...
 
struct  ValueConverter
 ValueConverter<T>::Type is the type of a LeafNode having the same dimensions as this node but a different value type, T. More...

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());
Templated block class to hold specific data types and a fixed number of values determined by Log2Dim....
Definition LeafNode.h:38
const Coord & origin() const

template<Index Log2Dim>
template<typename AccessorT >
void setValueOnlyAndCache ( const Coord & xyz,
bool val,
AccessorT &  )
inline

Change the value of the voxel at the given coordinates but preserve its state.

Note
Used internally by ValueAccessor.

◆ setValuesOff()

template<Index Log2Dim>
void setValuesOff ( )
inline

Mark all voxels as inactive but don't change their values.

◆ setValuesOn()

template<Index Log2Dim>
void setValuesOn ( )
inline

Mark all voxels as active but don't change their values.

◆ size()

template<Index Log2Dim>
static Index size ( )

◆ stealNode()

template<Index Log2Dim>
template<typename NodeT >
NodeT * stealNode ( const Coord & ,
const ValueType & ,
bool  )
inline

◆ stealNodes()

template<Index Log2Dim>
template<typename ArrayT >
void stealNodes ( ArrayT & ,
const ValueType & ,
bool  )
inline

◆ str()

template<Index Log2Dim>
std::string str ( ) const
inline

Return a string representation of this node.

◆ swap()

template<Index Log2Dim>
void swap ( Buffer & other)
inline

Exchange this node's data buffer with the given data buffer without changing the active states of the values.

◆ topologyDifference()

template<Index Log2Dim>
template<typename OtherType >
void topologyDifference ( const LeafNode< OtherType, Log2Dim > & other,
const bool &  )
inline

Difference this node's set of active values with the active values of the other node, whose ValueType may be different. So a resulting voxel will be active only if the original voxel is active in this LeafNode and inactive in the other LeafNode.

The last dummy argument is required to match the signature for InternalNode::topologyDifference.

Note
This operation modifies only active states, not values. Also, because it can deactivate all of this node's voxels, consider subsequently calling prune.

◆ topologyIntersection()

template<Index Log2Dim>
template<typename OtherType >
void topologyIntersection ( const LeafNode< OtherType, Log2Dim > & other,
const bool &  )
inline

Intersect this node's set of active values with the active values of the other node, whose ValueType may be different. So a resulting voxel will be active only if both of the original voxels were active.

The last dummy argument is required to match the signature for InternalNode::topologyIntersection.

Note
This operation modifies only active states, not values. Also note that this operation can result in all voxels being inactive so consider subsequently calling prune.

◆ topologyUnion()

template<Index Log2Dim>
template<typename OtherType >
void topologyUnion ( const LeafNode< OtherType, Log2Dim > & other,
const bool preserveTiles = false )
inline

Union this node's set of active values with the active values of the other node, whose ValueType may be different. So a resulting voxel will be active if either of the original voxels were active.

Note
This operation modifies only active states, not values.

◆ touchLeaf()

template<Index Log2Dim>
LeafNode * touchLeaf ( const Coord & )
inline

Return a pointer to this node.

◆ touchLeafAndCache()

template<Index Log2Dim>
template<typename AccessorT >
LeafNode * touchLeafAndCache ( const Coord & ,
AccessorT &  )
inline

◆ transientData()

template<Index Log2Dim>
Index32 transientData ( ) const
inline

Return the transient data value.

◆ valueMask()

template<Index Log2Dim>
const NodeMaskType & valueMask ( ) const
inline

◆ voxelizeActiveTiles()

template<Index Log2Dim>
void voxelizeActiveTiles ( bool = true)
inline

No-op.

This function exists only to enable template instantiation.

◆ writeBuffers()

template<Index Log2Dim>
void writeBuffers ( std::ostream & os,
bool toHalf = false ) const
inline

Write out the topology and the origin.

◆ writeTopology()

template<Index Log2Dim>
void writeTopology ( std::ostream & os,
bool toHalf = false ) const
inline

Write out just the topology.
