public static java.lang.String doubleToString(double d)

Produce a string from a double. The string "null" will be returned if the number is not finite.

Parameters:

d - A double.

Returns:

A String.

valueToString

public static java.lang.String valueToString(java.lang.Number number)
                                      throws java.lang.IllegalArgumentException

Produce a string from a Number.

Parameters:

number - A Number

Returns:

A String.

Throws:

java.lang.IllegalArgumentException - If n is a non-finite number.

unQuote

public static java.lang.String unQuote(java.lang.String value)

basicUnQuote

public static java.lang.String basicUnQuote(java.lang.String value)

quote

public static java.lang.String quote(java.lang.String string)

Produce a string in double quotes with backslash sequences in all the right places. A backslash will be inserted within </, producing <\/, allowing JSON text to be delivered in HTML. In JSON text, a string cannot contain a control character or an unescaped quote or backslash.

Parameters:

string - A String

Returns:

A String correctly formatted for insertion in a JSON text.

valueToString

public static java.lang.String valueToString(java.lang.Object value,
                                             int indentFactor,
                                             int intent,
                                             boolean simpleText,
                                             BaseItem reference)

Make a prettyprinted JSON text of an object value.

Warning: This method assumes that the data structure is acyclical.

Parameters:

value - The value to be serialized.

indentFactor - The number of spaces to add to each level of indentation.

intent - The indentation of the top level.

simpleText - Boolean for switch between text and Escaped-Text

reference - A Reference Object to generate new Objects like Factory Pattern

Returns:

a printable, displayable, transmittable representation of the object, beginning with { (left brace) and ending with } (right brace).

valueToString

public static java.lang.String valueToString(java.lang.Object value,
                                             boolean simpleText,
                                             BaseItem reference)

wrap

public static java.lang.Object wrap(java.lang.Object object,
                                    BaseItem reference)

Wrap an object, if necessary. If the object is null, return the NULL object. If it is an array or collection, wrap it in a JsonArray. If it is a map, wrap it in a JsonObject. If it is a standard property (Double, String, et al) then it is already wrapped. Otherwise, if it comes from one of the java packages, turn it into a string. And if it doesn't, try to wrap it in a JsonObject. If the wrapping fails, then null is returned.

Parameters:

object - The object to wrap

reference - The reference

Returns:

The wrapped value

repeat

public static java.lang.String repeat(char ch,
                                      int repeat)

Repeat a Char and return a simple String

Parameters:

ch - Char

repeat - Number of Repeat

Returns:

a String
