JSON QL

[jbee]

Maybe use https://docs.jsonata.org/ as inspiration.

Sketch

Recap: JsonPath has 3 important notations:

• .property (plain/unescaped)
• {property} ("escaped")
• [index]

Generally any query should be marked by using round brackets: (...)

The main function is to collect matching paths and with that matching nodes.

Stream<JsonValue> query(JsonQL);

Path Selectors

• ([...]) is a JsonArray + Predicate : JsonArray function to select elements based on a predicate
• ([*]) select all
• ({...}) is a JsonObject + Predicate : JsonObject function to select properties based on a predicate
• ({*}) select all
