The GetTokens method is a member of the ITagSet interface in the Sandbox namespace. This method is designed to retrieve all the tags present in the tag set as a collection of unique identifiers. Each tag is represented by a UInt32 token, which serves as a unique identifier for the tag within the set.

To use the GetTokens method, you need to have an instance of a class that implements the ITagSet interface. Once you have this instance, you can call the GetTokens method to retrieve the set of tag tokens.

Example usage:

ITagSet tagSet = GetTagSetInstance();
IReadOnlySet<UInt32> tokens = tagSet.GetTokens();
foreach (var token in tokens)
{
    // Process each token
}
