AnnBatesStampTranslator Object

Summary

AnnBatesStampTranslator defines a translator that converts the Bates stamp elements to a string expression. It can also convert a string expression to Bates stamp elements that can be saved and loaded using AnnBatesStampComposer.

Syntax
TypeScript
JavaScript
function lt.Annotations.BatesStamp.AnnBatesStampTranslator 
class lt.Annotations.BatesStamp.AnnBatesStampTranslator() 
Remarks

This class is used by AnnBatesStampComposer when saving or loading. It can also convert Bates stamp elements to/from a string.

A text expression is composed of the following symbols:

In this instance, the type is a Bates stamp number with 6 digits. Start is set to use all digits, and set to start from 1 with the auto increment feature. The prefix text is "before" and the suffix text is "after". This expression produces: "before000001after".

If the text expression does not conform to the format of either AnnBatesDateTime or AnnBatesNumber, then it is an AnnBatesText element. An example of AnnBatesText is "This is some text".

Provided below is an example of different Bates stamp elements that are converted to a string using AnnBatesStampTranslator:

{{BatesDateTime*Local*MM/dd/yyyy}} {{BatesNumber*6*1*1*1*before*after}} This is some text
. This expression renders as "01/11/1111 before000001after This is some text".

Example

This example translates Bates stamp elements to a string expression, and then loads it again.
