RemoveAt()

template<typename RepeatedType, typename IndexContainer = std::vector<int>>

int google::protobuf::util::RemoveAt	(	RepeatedType *	array,
		const IndexContainer &	indices )

Removes the elements at the indices specified by 'indices' from 'array' in time linear in the size of 'array' (on average, even when 'indices' is a singleton) while preserving the relative order of the remaining elements. The indices must be a container of ints in strictly increasing order, such as vector<int>, set<int> or initializer_list<int>, and in the range [0, N - 1] where N is the number of elements in 'array', and RepeatedType must be RepeatedField or RepeatedPtrField. Returns number of elements erased.

Assumes that 'indices' consists of [0 ... N-1].

RemoveIf()

template<typename T, typename Pred>

int google::protobuf::util::RemoveIf	(	RepeatedPtrField< T > *	array,
		const Pred &	pr )

For RepeatedPtrField. Removes all elements from 'array' for which unary predicate Pred pr is true. Relative ordering of elements left in the array stays the same. Returns number of removed elements. The predicate is invoked exactly once for each element of 'array' in order of its elements. Define your predicate like this: struct MyPredicate { bool operator()(const T* t) const { ... your logic ... } }; where T is going to be some derivation of ProtocolMessageGroup.

Alternatively, RepeatedPtrField supports the erase-remove idiom directly.

'write' is positioned at first element to be removed.
