| /** |
| * Function to get a JMeter property, or a default. Does not offer the option to |
| * store the value, as it is just as easy to refetch it. This is a |
| * specialisation of the __property() function to make it simpler to use for |
| * ThreadGroup GUI etc. The name is also shorter. |
| * |
| * Parameters: - property name - default value (optional; defaults to "1") |
| * |
| * Usage: |
| * |
| * Define the property in jmeter.properties, or on the command-line: java ... |
| * -Jpropname=value |
| * |
| * Retrieve the value in the appropriate GUI by using the string: |
| * ${__P(propname)} $(__P(propname,default)} |
| * |
| * Returns: - the property value, but if not found - the default value, but if |
| * not present - "1" (suitable for use in ThreadGroup GUI) |
| * @since 2.0 |
