Class ExpressionsVisitor.SelectorArrayNode

  • All Implemented Interfaces:
    com.fasterxml.jackson.core.TreeNode, com.fasterxml.jackson.databind.JsonSerializable, com.fasterxml.jackson.databind.node.JsonNodeCreator, Serializable, Iterable<com.fasterxml.jackson.databind.JsonNode>
    Enclosing class:
    ExpressionsVisitor
    public static class ExpressionsVisitor.SelectorArrayNode
extends com.fasterxml.jackson.databind.node.ArrayNode
    This is how we indicate to upstream operators that we are currently inside a selection statement. E.g. [{"a":1}, {"a":2}}].a will return this special subclass of array node. This is so that upstream operators (e.g. array indexes) can have special handling applied to them. For instance: [{"a":1}, {"a":2}}].a[0] does not return [1], but rather [1,2] Parenthesis can be used to drop this context, e.g.: ([{"a":1}, {"a":2}}]).a[0] returns [1]

      • addAsSelectionGroup

        public void addAsSelectionGroup​(com.fasterxml.jackson.databind.JsonNode group)
        Adds the specified elements to two lists: 1. Adds flattened results to array - operators that don't care about selection groups will just see this as a normal array 2. Adds non-flattened results to the separately-maintained selectionGroups list. This will be used selector-aware operators (e.g. array index) to apply appropriate semantics
        Parameters:
        group - JsonNode containing the group definitions
