Tree Navigation

"Casting" to Node Types (casting does not check that actual document matches the target)

• T as(Class<T extends JsonValue> type)
• JsonList<T> asList(Class<T extends JsonValue> type)
• JsonMap<V> asMap(Class<V extends JsonValue> type)
• and more of similar kind...

Tree Navigation

• JsonValue get(String path)
• JsonObject getObject(String path)
• JsonArray getArray(String path)
• JsonNumber getNumber(String path)
• JsonBoolean getBoolean(String path)
• JsonValue get(int index)
• and more of similar kind...

Drilling down...

JsonString str=root.getObject("a").getArray("b").getString(3)
// is the same as
JsonString str=root.getString("a.b[3]")

Traversing the actual tree to find nodes

• JsonValue#node(): from virtual to actual JSON tree 🗱
• JsonObect#find: return first matching JsonValue
• JsonNode#visit: visit matching nodes
• JsonNode#find: return first matching JsonNode
• JsonNode#count: count matching nodes
