## Detailed Description

template<typename MaskIterT, typename NodeT>
class openvdb::v10_0::tree::IteratorBase< MaskIterT, NodeT >

Base class for iterators over internal and leaf nodes.

This class is typically not instantiated directly, since it doesn't provide methods to dereference the iterator. Those methods (operator*(), setValue(), etc.) are implemented in the sparse and dense iterator subclasses.

## Constructor & Destructor Documentation

## ◆ IteratorBase() [1/3]

template<typename MaskIterT , typename NodeT >

IteratorBase | ( |  | ) |
| inline

## ◆ IteratorBase() [2/3]

template<typename MaskIterT , typename NodeT >

IteratorBase | ( | const MaskIterT & | iter,
|  | NodeT * | parent
| ) |  |
| inline

## ◆ IteratorBase() [3/3]

template<typename MaskIterT , typename NodeT >

IteratorBase | ( | const IteratorBase< MaskIterT, NodeT > & |  | ) |
| default

## Member Function Documentation

## ◆ getCoord() [1/2]

template<typename MaskIterT , typename NodeT >

Coord getCoord | ( |  | ) | const
| inline

Return the coordinates of the item to which this iterator is pointing.

## ◆ getCoord() [2/2]

template<typename MaskIterT , typename NodeT >

void getCoord | ( | Coord & | xyz | ) | const
| inline

Return in xyz the coordinates of the item to which this iterator is pointing.

## ◆ getParentNode()

template<typename MaskIterT , typename NodeT >

NodeT * getParentNode | ( |  | ) | const
| inline

Return a pointer to the node (if any) over which this iterator is iterating.

## ◆ increment() [1/2]

template<typename MaskIterT , typename NodeT >

void increment | ( |  | ) |
| inline

Advance to the next item in the parent node's table.

## ◆ increment() [2/2]

template<typename MaskIterT , typename NodeT >

void increment | ( | Index | n | ) |
| inline

Advance n items in the parent node's table.

## ◆ isValueOn()

template<typename MaskIterT , typename NodeT >

bool isValueOn | ( |  | ) | const
| inline

Return `true` if this iterator is pointing to an active value. Return `false` if it is pointing to either an inactive value or a child node.

## ◆ next()

template<typename MaskIterT , typename NodeT >

bool next | ( |  | ) |
| inline

Advance to the next item in the parent node's table.

## ◆ offset()

template<typename MaskIterT , typename NodeT >

Index offset | ( |  | ) | const
| inline

Return this iterator's position as an index into the parent node's table.

## ◆ operator bool()

template<typename MaskIterT , typename NodeT >

operator bool | ( |  | ) | const
| inline

Return `true` if this iterator is not yet exhausted.

## ◆ operator!=()

template<typename MaskIterT , typename NodeT >

bool operator!= | ( | const IteratorBase< MaskIterT, NodeT > & | other | ) | const
| inline

## ◆ operator++()

template<typename MaskIterT , typename NodeT >

IteratorBase & operator++ | ( |  | ) |
| inline

Advance to the next item in the parent node's table.

## ◆ operator=()

template<typename MaskIterT , typename NodeT >

IteratorBase & operator= | ( | const IteratorBase< MaskIterT, NodeT > & |  | ) |
| default

## ◆ operator==()

template<typename MaskIterT , typename NodeT >

bool operator== | ( | const IteratorBase< MaskIterT, NodeT > & | other | ) | const
| inline

## ◆ parent()

template<typename MaskIterT , typename NodeT >

NodeT & parent | ( |  | ) | const
| inline

Return a reference to the node over which this iterator is iterating.

Exceptions

  ValueError | if there is no parent node.

## ◆ pos()

template<typename MaskIterT , typename NodeT >

Index pos | ( |  | ) | const
| inline

Identical to offset.

## ◆ setValueOff()

template<typename MaskIterT , typename NodeT >

void setValueOff | ( |  | ) | const
| inline

If this iterator is pointing to a value, mark the value as inactive.

If this iterator is pointing to a child node, then the current item in the parent node's table is required to be inactive. In that case, this method has no effect.

## ◆ setValueOn()

template<typename MaskIterT , typename NodeT >

void setValueOn | ( | bool | on = `true` | ) | const
| inline

If this iterator is pointing to a value, set the value's active state. Otherwise, do nothing.

## ◆ test()

template<typename MaskIterT , typename NodeT >

bool test | ( |  | ) | const
| inline

Return `true` if this iterator is not yet exhausted.
