Class StringTemplate

java.lang.Object

us.abstracta.jmeter.javadsl.core.util.StringTemplate

public class StringTemplate
extends Object

String template engine allowing easy string regex matching and usual template engine resolution.

This engine uses a syntax inspired in mustache using {{}} as basic indicator of special treatment/replacement.

To check fo string regex matching you can have a template like

<root version="1.2">{{\d+}}</root>

and use matches(String). No need to escape regex special characters outside of {{}} .

To use regular string template resolution you can use templates like

<root version="1.2">{{value}}</root>

and use bind(String, Object) and solve() to get the resulting string of replacing each occurrence of {{}} with the bound value. Additionally, you can define default values for each replacement expression. In this example

<root version="1.2">{{value:3}}</root>

it will solve "value" to string "3" if no value is bound to "value" or if bound value is null. If a replacement has no binding value different from null and no default value is specified, then an exception will be generated. You can always specify an empty default value (like {{value:}}) which avoids the exception and generates an empty string instead.

You can even use one template for both regex matching or string template solving. Eg:

<root version="1.2">{{value:3~\d+}}</root>

can be used with matches(String) or with bind(String, Object) and solve().
