scriptella.driver.text
Class TextScriptExecutor

java.lang.Object
  scriptella.driver.text.TextScriptExecutor

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class TextScriptExecutor
extends java.lang.Object
implements java.io.Closeable, java.io.Flushable

Writes a text content to the output and performs properties expansion.

This class is a simplified template engine similar to Velocity, but of course less powerful. Nevertheless this executor is generally faster than external template engines and does not require any additional libraries.

Example:

Script:

 $rownum;$name;$surname;${email.trim().replaceAll('@','_at_')}
 

Parameters:

rownum	name	surname	email
1	John	G	john@nosuchhost.com

Result:

 1;John;G;john_at_nosuchhost.com
