Interface Segment

All Known Implementing Classes:

Segment.Child, Segment.Descendant

public sealed interface Segment
permits Segment.Child, Segment.Descendant

A segment: it applies its selectors to the children or descendants of a node (RFC 9535, Section 2.5).

For each input node, a segment concatenates the results of its selectors in their order. The segment result is the concatenation of these results, in the order of the input nodes.

Segment	Query text	Applies its selectors to
Segment.Child	[0, 'a'], .a, .*	the input node
Segment.Descendant	..[0, 'a'], ..a, ..*	the input node and all its descendants, in pre-order

For example, on {"a": {"a": 1}}, the query $..a selects {"a": 1} and then 1.
