IdGenerator

Description

The IdGenerator class allows you to generate IDs for objects.

Important points

• It supports two types of IDs: short and long.
• ShortIDs are 9-digit random numbers. They are not guaranteed be unique.
• Long IDs are string GUIDs. They are globally unique and 32-character long.

Static methods

nextLong

Generates a globally unique 32-digit object ID. The value is a string representation of a GUID value.

public static String nextLong()

• returns: string - generated 32-digit object ID

nextShort

Generates a random 9-digit random ID (code).

Note: The returned value is not guaranteed to be unique.

public static String nextShort()

• returns: String - generated random 9-digit code

Examples

{@code
  IdGenerator.nextLong();      // Possible result: "234ab342c56a2b49c2ab42bf23ff991ac"
  IdGenerator.nextShort();     // Possible result: "23495247"
  }
