Feature Request - allow all array elements in JsonPointerBasedFilter - updated

[DemonicTutor]

Currently JsonPointerBasedFilter only processes Json Arrays by index. eg /0/id.

With this change it is possible to extract all elements using a pointer in the form of //id:

source:

[
   {
      "id":1,
      "stuff":[
         {
            "name":"first",
            "type":"a"
         },
         {
            "name":"second",
            "type":"b"
         }
      ]
   },
   {
      "id":2,
      "stuff":[
         {
            "name":"third",
            "type":"c"
         },
         {
            "name":"fourth",
            "type":"d"
         }
      ]
   }
]

pointers:

"//id"
"//stuff//name"

result:

[
   {
      "id":1,
      "stuff":[
         {
            "name":"first"
         },
         {
            "name":"second"
         }
      ]
   },
   {
      "id":2,
      "stuff":[
         {
            "name":"third"
         },
         {
            "name":"fourth"
         }
      ]
   }
]

Any chance you could target at branch 2.16? master branch is for a 3.0 release that is probably a long way away? Jackson 2 uses com.fasterxml.jackson instead of tools.jackson package?

[cowtowncoder]

Right, +1 for targeting 2.16 for reasons @pjfanning mentioned. Would be happy to merge (assuming CLA handled -- added a label as I am not 100% if you provided one; if you did that's fine I can check later on)

[cowtowncoder]

Checked it: yes, we do have CLA. So that's not a problem.

[cowtowncoder]

@DemonicTutor Would be happy to merge but I think we'd really like this against 2.16 branch.

Could you create a new PR?

[cowtowncoder]

Merged via #1036 to 2.16.

[DemonicTutor]

ah awesome! thanks @cowtowncoder for handling that for me :)

Np @DemonicTutor !
