47. def extractAssets(boxes: IndexedSeq[ErgoBoxCandidate]): (Map[Digest32Coll, Long], Int)

    

    Extracts a mapping (assets -> total amount) from a set of boxes passed as a parameter.

    Extracts a mapping (assets -> total amount) from a set of boxes passed as a parameter. That is, the method is checking amounts of assets in the boxes(i.e. that a box contains positive amount for an asset) and then summarize and group their corresponding amounts.

    boxes

    - boxes to check and extract assets from

    returns

    a mapping from asset id to to balance and total assets number

59. def subtractTokenColls(reducedTokens: TokenColl, subtractedTokens: TokenColl): TokenColl

    

    Compute the difference between reducedTokens collection and subtractedTokens collection.

    Compute the difference between reducedTokens collection and subtractedTokens collection. It can be thought as reducedTokens - subtractedTokens operation.

    Each collection can have many (tokenId, amount) pairs with the same tokenId. The method works by first combining all the pairs with the same tokenId and then computing the difference. The resulting collection contain a single pair for each tokenId and those token ids form a subset of tokens from the argument collections.

    One concrete use case to think of is subtractTokenColls(outputTokens, inputTokens). In this case the resulting collection of (tokenId, amount) pairs can be interpreted as: - when amount < 0 then it is to be burnt - when amount > 0 then it is to be minted

    reducedTokens

    the tokens to be subracted from

    subtractedTokens

    the tokens which amounts will be subtracted from the corresponding tokens from reducedTokens

    returns

    the differences between token amounts (matched by token ids)

60. def subtractTokens(reducedTokens: IndexedSeq[Token], subtractedTokens: IndexedSeq[Token]): TokenColl

    

    Compute the difference between reducedTokens collection and subtractedTokens collection.

    Compute the difference between reducedTokens collection and subtractedTokens collection.
