Detailed Description

SGLMap::Iterator is a iterator for SGLMap and points towards a key value pair in the SGLMap. This can be used to iterate over the SGLMap sequentially. If you do not need to modify the SGLMap while iterating, use SGLMap::ConstIterator instead. This is a template based class with no separate source file.

Implementation Details

SGLMap::Iterator stores a pointer to the memory location where SGLMap keeps all its data.

const K& key();

Returns the key in the key value pair that this iterator points to.

If this iterator is SGLMap::end, using this function will crash.

bool operator!=(SGLMap::Iterator x);

Checks if this iterator points to a different key value pair from x.

SGLMap::Iterator& operator++();

Increments the iterator to point towards the next key value pair and returns the new iterator.

SGLMap::Iterator is circular, incrementing SGLMap::end gives SGLMap::begin and decrementing SGLMap::begin gives SGLMap::end.

SGLMap::Iterator operator++(int);

Increments the iterator to point towards the next key value pair and returns the old iterator.

SGLMap::Iterator is circular, incrementing SGLMap::end gives SGLMap::begin and decrementing SGLMap::begin gives SGLMap::end.

SGLMap::Iterator operator--(int);

Decrements the iterator to point towards the previous key value pair and returns the old iterator.

SGLMap::Iterator is circular, incrementing SGLMap::end gives SGLMap::begin and decrementing SGLMap::begin gives SGLMap::end.

SGLMap::Iterator& operator--();

Decrements the iterator to point towards the previous key value pair and returns the new iterator.

SGLMap::Iterator is circular, incrementing SGLMap::end gives SGLMap::begin and decrementing SGLMap::begin gives SGLMap::end.

bool operator==(SGLMap::Iterator x);

Checks if this iterator points to the same key value pair as x.

V& value();

Returns a reference to the value in the key value pair that this iterator points to.

This returns a reference and not a copy. Assigning to the returned reference (using it as a lvalue) modifies the SGLMap.

If this iterator is SGLMap::end, using this function will crash.
