Methods

Name Return Value Summary
fromString Uuid

Generates a UUID from a string representation of the UUID.
generate Uuid

Generates a new UUID.
isEqual boolean

Tests whether two UUIDs are equal.
isNull boolean

Tests whether a UUID is null.
print None

Prints a UUID to the program log, as a text label followed by the UUID value.
toString string

Generates a string representation of a UUID. However, because UUIDs are represented in JavaScript as strings, this is in effect a no-op.

Method Details

(static) fromString( string ) → {Uuid}
Returns: A UUID if the given string is valid, null otherwise.

Generates a UUID from a string representation of the UUID.

Parameters

Name Type Description
string string

A string representation of a UUID. The curly braces are optional.

Example

Valid and invalid parameters.

var uuid = Uuid.fromString("{527c27ea-6d7b-4b47-9ae2-b3051d50d2cd}");
print(uuid); // {527c27ea-6d7b-4b47-9ae2-b3051d50d2cd}

uuid = Uuid.fromString("527c27ea-6d7b-4b47-9ae2-b3051d50d2cd");
print(uuid); // {527c27ea-6d7b-4b47-9ae2-b3051d50d2cd}

uuid = Uuid.fromString("527c27ea");
print(uuid); // null
(static) generate( ) → {Uuid}
Returns: A new UUID.

Generates a new UUID.

Example

Generate a new UUID and reports its JavaScript type.

var uuid = Uuid.generate();
print(uuid);        // {nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
print(typeof uuid); // string
(static) isEqual( idA, idB ) → {boolean}
Returns: true if the two UUIDs are equal, otherwise false.

Tests whether two UUIDs are equal.

Parameters

Name Type Description
idA Uuid

The first UUID to compare.

idB Uuid

The second UUID to compare.

Example

Demonstrate true and false cases. 

var uuidA = Uuid.generate();
var uuidB = Uuid.generate();
print(Uuid.isEqual(uuidA, uuidB)); // false
uuidB = uuidA;
print(Uuid.isEqual(uuidA, uuidB)); // true
(static) isNull( id ) → {boolean}
Returns: true if the UUID equals Uuid.NULL or is null, otherwise false.

Tests whether a UUID is null.

Parameters

Name Type Description
id Uuid

The UUID to test.

Example

Demonstrate true and false cases. 

var uuid; // undefined
print(Uuid.isNull(uuid)); // false
uuid = Uuid.generate();
print(Uuid.isNull(uuid)); // false
uuid = Uuid.NULL;
print(Uuid.isNull(uuid)); // true
uuid = null;
print(Uuid.isNull(uuid)); // true
(static) print( label, id )

Prints a UUID to the program log, as a text label followed by the UUID value.

Parameters

Name Type Description
label string

The label to print.

id Uuid

The UUID to print.

Example

Two ways of printing a label plus UUID.

var uuid = Uuid.generate();
Uuid.print("Generated UUID:", uuid); // Generated UUID: {nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
print("Generated UUID: " + uuid);    // Generated UUID: {nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
(static) toString( id ) → {string}
Returns: - A string representation of the UUID.

Generates a string representation of a UUID. However, because UUIDs are represented in JavaScript as strings, this is in effect a no-op.

Parameters

Name Type Description
id Uuid

The UUID to generate a string from.
