cArray::Iterator Class Reference

Description

Iterates through elements in a cArray, skipping holes (slots containing nullptr).

Usage:

for (cArray::Iterator it(array); !it.end(); ++it) {
    cObject *item = *it;
    ...
}

Constructor & Destructor Documentation

Iterator()

Iterator ( const cArray &  a, bool  atHead = true  )

inline

Constructor. Iterator will walk on the array passed as argument. The starting object will be the first (if atHead==true) or the last (atHead==false) object in the array, not counting empty slots.

Member Function Documentation

init()

void init	(	const cArray &	a,
		bool	atHead = true
	)

Reinitializes the iterator object.

operator*()

cObject* operator* ( ) const

inline

Returns a pointer to the current object, or nullptr if the iterator is not at a valid position.

References cArray::get().

end()

bool end ( ) const

inline

Returns true if the iterator has reached either end of the array.

References cArray::size().

operator++() [1/2]

Iterator& operator++ ( )

inline

Prefix increment operator (++it). Moves the iterator to the next non-empty slot in the array. It has no effect if the iterator has reached either end of the array.

operator++() [2/2]

Iterator operator++ ( int  )

inline

Postfix increment operator (it++). Moves the iterator to the next non-empty slot in the array, and returns the iterator's previous state. It has no effect if the iterator has reached either end of the array.

operator--() [1/2]

Iterator& operator-- ( )

inline

Prefix decrement operator (–it). Moves the iterator to the previous non-empty slot in the array. It has no effect if the iterator has reached either end of the array.

operator--() [2/2]

Iterator operator-- ( int  )

inline

Postfix decrement operator (it–). Moves the iterator to the previous non-empty slot in the array, and returns the iterator's previous state. It has no effect if the iterator has reached either end of the array.
