Method Detail

asBoolean

boolean asBoolean()

Coerces underlying value to boolean according to the rules of Javascript coercion.

asNumber

double asNumber()

Coerces the underlying value to a number according to the rules of Javascript coercion.

asString

String asString()

Coerces the underlying value to a String according to the rules of JavaScript coercion.

getType

JsonType getType()

Returns an enumeration representing the fundamental JSON type.

toJson

String toJson()

Returns a serialized JSON string representing this value.

Returns:

jsEquals

boolean jsEquals(JsonValue value)

Equivalent of Javascript '==' operator comparison between two values.

toNative

Object toNative()

If used in a GWT context (dev or prod mode), converts the object to a native JavaScriptObject suitable for passing to JSNI methods. Otherwise, returns the current object in other contexts, such as server-side use.
