Class PrettyPrinter

java.lang.Object

org.neo4j.values.utils.PrettyPrinter

All Implemented Interfaces:

AnyValueWriter<RuntimeException>, ValueWriter<RuntimeException>

public class PrettyPrinter
extends Object
implements AnyValueWriter<RuntimeException>

Pretty printer for AnyValues.

Used to format AnyValue as a json-like string, as following:

• nodes: (id=42 :LABEL {prop1: ["a", 13]})
• edges: -[id=42 :TYPE {prop1: ["a", 13]}]-
• paths: (id=1 :L)-[id=42 :T {k: "v"}]->(id=2)-...
• points are serialized to geojson
• maps: {foo: 42, bar: "baz"}
• lists and arrays: ["aa", "bb", "cc"]
• Numbers: 2.7182818285
• Strings: "this is a string"
