Method Detail

doubleToString

public final 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.

isNumeric

public static final boolean isNumeric(java.lang.String strNum)

getExcelRange

public static final SimpleList<Pos> getExcelRange(java.lang.String tag)

valueToString

public static final 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.

unQuoteControlCharacter

public static final java.lang.String unQuoteControlCharacter(java.lang.CharSequence value)

unQuote

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

basicUnQuote

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

quote

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

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.

simpleText - Boolean for switch between text and Escaped-Text

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

converter - The Converter to transform Item

Returns:

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

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

randomString

public static java.lang.String randomString(int length)

Returns a random String of numbers and letters (lower and upper case) of the specified length. The method uses the Random class that is built-in to Java which is suitable for low to medium grade security uses. This means that the output is only pseudo random, i.e., each number is mathematically generated so is not truly random.

The specified length must be at least one. If not, the method will return null.

Parameters:

length - the desired length of the random String to return.

Returns:

a random String of numbers and letters of the specified length.
