Member Function Documentation

unsigned char pcl::octree::OctreeKey::getChildIdxWithDepthMask

(

unsigned int

depthMask

)

const [inline]

get child node index using depthMask

Parameters:

[in]

depthMask

bit mask with single bit set at query depth

Returns:

child node index

Definition at line 128 of file octree_key.h.

bool pcl::octree::OctreeKey::operator<=

(

const OctreeKey &

b

)

const [inline]

Operator<= for comparing octree keys with each other.

Returns:

"true" if key indices are not greater than the key indices of b ; "false" otherwise.

Definition at line 88 of file octree_key.h.

bool pcl::octree::OctreeKey::operator==

(

const OctreeKey &

b

)

const [inline]

Operator== for comparing octree keys with each other.

Returns:

"true" if leaf node indices are identical; "false" otherwise.

Definition at line 79 of file octree_key.h.

bool pcl::octree::OctreeKey::operator>=

(

const OctreeKey &

b

)

const [inline]

Operator>= for comparing octree keys with each other.

Returns:

"true" if key indices are not smaller than the key indices of b ; "false" otherwise.

Definition at line 97 of file octree_key.h.
