Instance methods¶

void Add(long val)¶

Returns the number of values in the collection. Elements in collections are indexed from 0 to count()-1.

Returns:	Number of values in the collection.
Return type:	int

long Get(int position)¶

Gets the value at the given position.

Arguments:	position (int) – The considered position (must be non negative and strictly smaller than the number of values in the collection).
Returns:	The value at the given position

IEnumerator<long> GetEnumerator()¶

string ToString()¶

Returns a string representation of the values in the collection in the format { val0, val1, ..., valN }.

Returns:	A String representation of the collection
Return type:	string

Overloaded operators and indexers¶
