Iterator

An iterator is an object used to traverse the elements of a sequence.

bool hasValue();

Returns true if there's at least one element remaining in the sequence, i.e. if calling value() is allowed.

Element value();

Returns the next element from the sequence. Calling this function is not allowed if hasValue() returns false.

void increment();

Advances the iterator to the next element in the sequence. Calling this function is not allowed if hasValue() returns false.

bool all<T, I>(I& it, bool(T&) predicate)

Returns true if all remaining elements satisfy the predicate.

bool all<T: Copyable, I>(I& it, bool(T) predicate)

Returns true if all remaining elements satisfy the predicate.

bool any<T, I>(I& it, bool(T&) predicate)

Returns true if any remaining element satisfies the predicate.

bool any<T: Copyable, I>(I& it, bool(T) predicate)

Returns true if any remaining element satisfies the predicate.

bool none<T, I>(I& it, bool(T&) predicate)

Returns true if no remaining element satisfies the predicate.

bool none<T: Copyable, I>(I& it, bool(T) predicate)

Returns true if no remaining element satisfies the predicate.
