STL compatible iterator.

---

Iterator used to traverse the grid using STL or STL like code.

Constructor & Destructor Documentation

iterator()

Burger::GridIndexBox::iterator::iterator ( const GridIndexBox * pParent )

inline

Default constructor.

---

Create an iterator for GridIndexPoints

Parameters

pParent

Pointer to the parent GridIndexPoints class

Member Function Documentation

advance()

void BURGER_API Burger::GridIndexBox::iterator::advance

(

void

)

Step to the next data entry.

---

Point at next element in the iteration. Will assert if it's called when it's already reached the end of the data.

See also

operator++() or AdvanceInCell(void)

AdvanceInCell()

uint_t BURGER_API Burger::GridIndexBox::iterator::AdvanceInCell

(

void

)

Step to the next data entry in the current array.

---

Go to the next valid element in the current cell. If the end of the cell is reached, set m_uCurrentCellArrayIndex to UINTPTR_MAX and return FALSE. Otherwise point m_uCurrentCellArrayIndex at the valid element, and return TRUE.

Returns

TRUE if data was found, FALSE if the end of the array was reached.

See also

operator++() or advance(void)

at_end()

uint_t Burger::GridIndexBox::iterator::at_end ( void ) const

inline

TRUE if the iterator is at the end of the data

---

Returns

FALSE if the is more data remaining, TRUE if data is exhausted.

operator*()

Burger::GridIndexBox::Entry & Burger::GridIndexBox::iterator::operator* ( ) const

inline

Access the entry with a reference.

---

Allows the used of the * operator to dereference the underlying data via a reference.

Returns

Reference to the data entry.

See also

operator->() const

operator++()

void Burger::GridIndexBox::iterator::operator++ ( )

inline

Step to the next data entry.

---

Iterate over the data until the next valid data chunk is found. If the iterator is already at the end of the data, no action is performed.

See also

advance(void)

operator->()

Burger::GridIndexBox::Entry * Burger::GridIndexBox::iterator::operator-> ( ) const

inline

Access the entry with a reference.

---

Allows the used of the * operator to dereference the underlying data via a pointer.

Returns

Pointer to the data entry.

operator*() const
