All Implemented Interfaces:

Serializable, Guard

public class FreeMarkerPermission
extends BasicPermission

A class representing all FreeMarker-related permissions. Currently available permissions are:

modifyTemplate	Permits invocation of various template methods that can be used to modify the template in such a way as to breach security. Specifically, Template.getRootTreeNode(), TemplateCore.getMacros(), Template.setParent(Configurable), and Template.containingElements(int, int).
setSecure	Permits invocation of Configuration.setSecure(boolean) with false argument (thus turning off security of a secure configuration).
setScriptEngineConfiguration	Permits invocation of FreeMarkerScriptEngine.setConfiguration(freemarker.template.Configuration) or specifying a configuration object within the engine's bindings under name FreeMarkerScriptConstants.CONFIGURATION.
setScriptEngineFactoryConfiguration	Permits invocation of FreeMarkerScriptEngineFactory.setConfiguration(freemarker.template.Configuration).
setTemplateLoader	Permits setting an arbitrary template loader using Configuration.setTemplateLoader(freemarker.cache.TemplateLoader). Note that various setXxxForTemplateLoading() methods are not checked for this permission, as they internally all create trusted template loaders.
