Method Details

create

public static JsonBuilder create()

createFrom

public static JsonBuilder createFrom(JsonValue arg)

Create a builder from a JsonValue.

If the argument is an object or array, use it to initialize the builder.

If the argument is a JSON primitive (string, number, boolean or null),

Otherwise thrown IllegalArgumentException.

copy

public static JsonValue copy(JsonValue arg)

Create a safe copy of a JsonValue.

If the JsonValue is a structure (object or array), copy the structure recursively.

If the JsonValue is a primitive (string, number, boolean or null), it is immutable so return the same object.

buildObject

public static JsonObject buildObject(Consumer<JsonBuilder> setup)

Build a JsonObject. The outer object is created and then the setup function called to fill in the contents.

 buildObject(builder->{
     builder.pair("key", 1234);
 });
 

Parameters:

Returns:
