Method Detail

arrIndexOf

static int arrIndexOf(a : Array, o : Object)

Returns the array index of o in a. Comparisons are performed with strict equals (===).

Parameters:

a –

o –

Returns:

numIsNaN

static boolean numIsNaN(v : Object)

Returns v == null || isNaN(v).

Parameters:

v – any value.

Returns:

Since:

3.2

numMod

static Number numMod(v : Number, mod : Number)

Calculates a mod b, but the result is not allowed to be negative.

Parameters:

v – a

mod – b

Returns:

a mod b if a >= 0, b + a mod b, if a < 0.

Since:

3.2

numRound

static Number numRound(v : Number, intUnit : int)

Rounds v to the nearest value that can be divided by intUnit.

Parameters:

v –

intUnit –

Returns:

Since:

3.2

strDecodeBase64

static String strDecodeBase64(s : String)

Returns the result of decoding s from its base-64 equivalent.

Parameters:

s –

Returns:

Since:

3.2

strEmpty

static boolean strEmpty(s : String)

Returns whether s is null or an empty string.

Parameters:

s –

Returns:

Since:

3.2

strEncodeBase64

static String strEncodeBase64(s : String)

Returns the result of encoding s to its base-64 equivalent.

Parameters:

s –

Returns:

Since:

3.2

strEndsWith

static boolean strEndsWith(s : String, strTest : String)

Returns whether s ends with strTest.

Parameters:

s –

strTest –

Returns:

Since:

3.2

Returns s with the following four characters replaced by their escaped equivalent: & < > ". This method also replaces any character that is not a valid XML character (valid character codes are: 0x09, 0x0A, 0x0D, 0x20-0xD7FF, 0xE000-0xFFFD, 0x10000-0x10FFFF) with "\uXX" where XX is the unicode hex value of the character.

Parameters:

s –

Returns:

Since:

3.2

strTrim

static String strTrim(s : String)

Returns s trimmed of trailing and leading spaces (anything matching the regexp /\s/).

Parameters:

s –

Returns:

Since:

3.2

strTruncate

static String strTruncate(s : String, intMax : int, strEllipsis : String, fltPos : Number)

Limits s to length intMax by placing an ellipsis in values that are too long.

Parameters:

s –

intMax – the maximum length of the string returned by this method.

strEllipsis – the ellipsis to use. "..." is used by default.

fltPos – the placement of the ellipsis as a value between 0 and 1. 1, the default, means that the ellipsis comes at the end of the truncated string. Other values mean that the head and tail of the string will be returned with the ellipsis somewhere in the middle.

Returns:

Since:
