JsonSolver

Type Members

type CONT = List[JsonWrapper]
type T = JsonWrapper
type U = List[JsonWrapper]

type U stands for the continuation that following methods pass to themselves.
type U stands for the continuation that following methods pass to themselves.
Ideally it's just a closure that can implement getNext(curr: (T, U), tag: String, assoc: String): Iterable[(T, U)]
So options include
type U = List[MyWrapper] and type U = PartialFunction[(String, String), List[MyWrapper]] // basically getNext (tag, assoc)
The continuation is very good when getting the kids is expensive, like a DB query, eh?

def children(root: T, xe: Option[XpElement]): (T, U)

prepare to start from a node, figure out the continuations.
prepare to start from a node, figure out the continuations.
This is only used to start, from the root - then getNext is used
You can return an actual list of nodes or a callback that you then call from getNext to get the actuals
root
the node we'll start resolving from
xe
- optional the current path element - you can use cond to filter result set directly when querying

reduce the current set of possible nodes based on the given condition. Note that the condition may be null - this is still called to give you a chance to cleanup?
This default implementation may be ok for most resolvers
NOTE - if you choose to filter in getNext, then you don't have to filter here...
curr
the list of (currelement, continuation) to reduce
