6. Filters

Some expressions inside values, conditions or loops may be filtered, for example you may to sort an array or list inside the template, using ":sorted" filter:

{% for element : unsorted_array:sorted %}
 {{ element }}
{% endfor %}

You can set filters to parentheses, strings, numbers or values, i.e. (1 + 1):<filter>, "":<filter>, 1:<filter> or name:<filter>.

If you want to specify multiple filters just use value:<filter1>:<filter2>:<filter3>

Also you can add your own filters if you want, just use Te4j.getFilters().add(Filter).
