JValue

Return unboxed values from JSON

Example:

JObject(JField("name", JString("joe")) :: Nil).values == Map("name" -> "joe")

Concatenate with another JSON. This is a concatenation monoid: (JValue, ++, JNothing)

Example:

JArray(JInt(1) :: JInt(2) :: Nil) ++ JArray(JInt(3) :: Nil) ==
JArray(List(JInt(1), JInt(2), JInt(3)))

Return nth element from JSON. Meaningful only to JArray, JObject and JField. Returns JNothing for other types.

Example:

JArray(JInt(1) :: JInt(2) :: Nil)(1) == JInt(2)

Return direct child elements.

Example:

JArray(JInt(1) :: JInt(2) :: Nil).children == List(JInt(1), JInt(2))

When this org.json4s.JValue is a org.json4s.JNothing or a org.json4s.JNull, this method returns scala.None When it has a value it will return scala.Some

When this org.json4s.JValue is a org.json4s.JNothing, this method returns scala.None When it has a value it will return scala.Some

Return a diff.
