Class TrackingCodeBuilder

public class TrackingCodeBuilder
extends java.lang.Object
Provides a unique random tracking code builder. The build method will ensure the tracking number is globally unique across both transaction and transaction history tables. If an existing tracking code is found, the build method will continue to generate a new tracking codes until it has created a globally unique value. If a unique value has not been generated after 100 attempts a IllegalArgumentException will be thrown. Examples Please find the tracking code builder examples below.

Create Transaction Tracking Code

The example below is creating an unique transaction tracking code and prefixing it with the form code and postfixing it with a test environment indicator. 
 class FluentTrackingNumberService {
     String invoke(SvcDef svcDef, Form form, HttpServletRequest request, User user) {
         return new TrackingCodeBuilder()
             .setPrefix(form.formCode + "-")
             .setPostfix("-TEST")
             .build()
     }
 }

Method Detail

setPrefix

public TrackingCodeBuilder setPrefix​(java.lang.String prefix) Set the tracking code value to prefix random component.
Parameters:
prefix - the tracking code prefix
Returns:
the tracking code builder

setPostfix

public TrackingCodeBuilder setPostfix​(java.lang.String postfix) Set the tracking code value to postfix random component.
Parameters:
postfix - the tracking code post
Returns:
the tracking code builder

setRandomLength

public TrackingCodeBuilder setRandomLength​(int randomLength) Set the random component character length. The default length is 7.
Parameters:
randomLength - the random component character length
Returns:
the tracking code builder

setRandomChars

public TrackingCodeBuilder setRandomChars​(java.lang.String randomChars) Set the character values to be used in the random component. The default values include: BCDFGHJKLMNPQRSTVWXYZ23456789
Parameters:
randomChars - the character values to be used in the random component.
Returns:
the tracking code builder

trackingCodeExists

public boolean trackingCodeExists​(java.lang.String trackingCode) Return true if the specified tracking code is already used.
Parameters:
trackingCode - the tracking code value to check (must not be null or an empty string)
Returns:
true if the tracking code value is already in use or there was an error during lookup

build

public java.lang.String build() Return a new random transaction tracking code (tracking number) for the specified properties. This method will ensure the tracking number is globally unique across both transaction and transaction history tables. If an existing tracking code is found, this method will continue to generate a new tracking codes until a globally unique value is found. If this method cannot generate a unique value after 10 attempts it will throw an IllegalArgumentException If a unique tracking code is found, the code is also stored in the tracking_number table that records all unique codes.
Returns:
new random transaction tracking code (tracking number) for the specified properties.
