Examples of freemarker.template.SimpleHash

freemarker.template.SimpleHash

A simple implementation of the TemplateHashModelEx interface, using an underlying {@link Map} or {@link SortedMap}.

This class is thread-safe if you don't call the put or remove methods after you have made the object available for multiple threads.
Note:
As of 2.0, this class is unsynchronized by default. To obtain a synchronized wrapper, call the {@link #synchronizedWrapper} method.
