QUESTION
I have a sample Json response as followed below
I know how to filter it using comparison actions like == or >
e.g. I can use $.books[?(@.pages > 460)] to retrieve books with more than 460 pages or
similarly $.books[?(@.pages != 352)] to retrieve books with not 352 pages.
But how can I filter this Json to retrieve books with title containing "Java" substring or published in 2014 year (actually substring too)?
The sample Json is:
ANSWER
Answered 2021-Jan-04 at 22:02Raw JSON Path doesn't do this, but depending on the implementation you're using, it might be supported.
We're currently in progress writing a formal specification. One of the open issues is the breadth of expression support we want. Feel free to add a comment. Once the spec is defined and published, I imagine most implementations will update to adhere.
QUESTION
I simplified the relationships in the model
...ANSWER
Answered 2020-Aug-21 at 00:07I am not exactly sure what is the desired output but have a look at this.
You can see the outer level are genres, followed by nested publishers with nested books within.
- Firstly, I got all the genres.
- Then I got the books and publishers with
$lookup. - I used
$unwindto separate publishers. - I added books with
$addFieldsto each publisher for filtering it later. - I used
$groupto get relevant elements and$addToSetto make an array of publishers. - Finally, I used
$projectwith$mapand$filterto get relevant books for each publisher.
QUESTION
I write this data as an example. I have two different collections books and publishers

QUESTION
I have created a Non fungible Evolvable token, shown below
ANSWER
Answered 2020-Jan-20 at 15:35The Accounts library has 2 good examples about using accounts with Tokens SDK:
https://github.com/corda/accounts/tree/master/examples/tokens-integration-test/src/integrationTest/kotlin/com/r3/corda/lib/accounts/examples/tokensTest
Here they transfer a fungible token between 2 accounts, in your case use the non-fungible version of the flow (i.e. MoveNonFungibleTokens): https://github.com/corda/accounts/blob/32e7ae0044ce3b7c8640154dc333e61261251371/examples/tokens-integration-test/src/integrationTest/kotlin/com/r3/corda/lib/accounts/examples/tokensTest/IntegrationTest.kt#L134
Also make sure that you specify the changeHolder in the flow; if your sending account has 1 token with quantity 5 and you only want to send quantity 2, then the change must go back to your sending account, if you leave the changeHolder empty; the MoveNonFungibleTokens flow will assign the change to the initiating node.

QUESTION
At my work, I'm trying to create more modular systems, as we tend to use similar mechanics in our games that have minor variances. To do this, I have been making use of interfaces, but have been getting stumped on certain problems, particularly ones relating to the addition of small features.
EXAMPLE:
Take for instance our evolution system. I have created the IEvolvable interface, which has a property for the evolution level and an Evolve() method.
...ANSWER
Answered 2018-Sep-06 at 04:48Once you are running into these types of issues it becomes evident I think that OOP has limitations, or rather it makes some things too easy. That doesn't mean it should be scrapped entirely and something else adopted, there's a lot we can still use it for. What if rather than using the interface you make meaningful changes to directly you pass around a service interface that acts as an adapter to the internal interface.

Install evolvable
The Evolvable module makes it possible to implement evolutionary behaviors for any class by defining a .search_space class method and #value instance method. Then to evolve instances, initialize a population with .new_population and invoke the #evolve method on the resulting population object.
