Class JsonPointerIterator

java.lang.Object
io.vertx.reactivex.core.json.pointer.JsonPointerIterator
All Implemented Interfaces:
io.vertx.lang.rx.RxDelegate
public class JsonPointerIterator extends Object implements io.vertx.lang.rx.RxDelegate
The JsonPointerIterator is used by the read/write algorithms of the JsonPointer to read/write the querying data structure
Every method takes the currentValue as parameter, representing the actual value held by the query algorithm.
Implementations of this interface should be stateless, so they can be reused
You can implement this interface to query the structure you want using json pointers

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
