Type Members

type Json = Any

A type alias for all Json forms.
A type alias for all Json forms. Json values should be restricted by convention to only those types used to represent Json.
type JsonArray = Seq[Json]

A type alias for Json Arrays.
type JsonObject = Map[String, Json]

A type alias for of Json Objects.
case class jfield(ilist: Any*) extends Product with Serializable

An extractor for nested Json values.
An extractor for nested Json values.
ilist
a list of values that are either strings or integers
- A string selects the value of a JsonObject name-value pair where the name equals the string.
- An integer i selects the ith elements of a JsonArray.
Example:
1. val A = jfield("a") val B = jfield("b") val C = jfield("c") jval match { case a:A & b:B => foo(a,b) case c:C => bar(c) }

Example:

val A = jfield("a")
val B = jfield("b")
val C = jfield("c")
jval match {
  case a:A & b:B => foo(a,b)
  case c:C => bar(c)
}

def Compact(j: Json, safe: Boolean = false): String

A Json unparser.
A Json unparser. It produces the most compact single line string form.
j
a Json tree.
safe
if false bad data types in tree will throw exceptions; if true no exceptions are thrown and error information is included in the output (default is false).
returns
the Json string for the tree.
def Json(s: String): Json

A Json parser.
A Json parser.
s
a Json string.
returns
the Json tree resulting from parsing the string.
def JsonArray(elements: Json*): JsonArray

the constructed Json Object.
def Pretty(j: Json, indent: Int = 0, width: Int = 50, count: Int = 6, safe: Boolean = false): String

A Json unparser.
A Json unparser. It produces a multiple line form designed for human readability.
j
a Json tree.
indent
the number of characters to indent the entire output (default is 0).
width
the maximum number of character that should be on a line (default is 50). This is only a goal; in practice some may contain more characters.
count
The maximum number of array elements that should be placed on a single line (default is 6).
safe
if false bad data types in tree will throw exceptions; if true no exceptions are thrown and error information is included in the output (default is false).
