Method Details

getInstanceId

String getInstanceId()

Returns an identifier of this Turbine instance that is unique both on the server and worldwide.

Returns:

A String with the instance identifier.

getUniqueId

String getUniqueId()

Returns an identifier that is unique within this Turbine instance, but does not have random-like appearance.

This method is intended to work fast; it can be used for creating names of temporary files.

Returns:

A String with the non-random looking instance identifier.

getPseudorandomId

String getPseudorandomId()

Returns a unique identifier that looks like random data.

This method provides identifiers in a way that makes it hard to guess or count, but still ensures their uniqueness within this instance of Turbine. It can be used for generating cookies or other data that travels back and forth between server and browser, and is potentially security sensitive.

Returns:

A String with the random looking instance identifier.
