# Classpath finder
# ================
# The classpath finder currently needs to load every single JMeter class to find
# the classes it needs.
# For non-GUI mode, it's only necessary to scan for Function classes, but all classes
# are still loaded.
# All current Function classes include ".function." in their name,
# and none include ".gui." in the name, so the number of unwanted classes loaded can be
# reduced by checking for these. However, if a valid function class name does not match
# these restrictions, it will not be loaded. If problems are encountered, then comment
# or change the following properties:
classfinder.functions.contain=.functions.
classfinder.functions.notContain=.gui.

<h4>Incompatible changes</h4>
<ul>
<li></li>
<li>
To reduce the number of classes loaded in non-GUI mode,
Functions will only be found if their classname contains the string
'.functions.' and does not contain the string '.gui.'.
All existing JMeter functions conform to this restriction.
To revert to earlier behaviour, comment or change the properties classfinder.functions.* in jmeter.properties.
