Example 3 with TemplateModelIterator

use of freemarker.template.TemplateModelIterator in project freemarker by apache.

the class Environment method getKnownVariableNames.

/**
 * Returns a set of variable names that are known at the time of call. This includes names of all shared variables
 * in the {@link Configuration}, names of all global variables that were assigned during the template processing,
 * names of all variables in the current name-space, names of all local variables and loop variables. If the passed
 * root data model implements the {@link TemplateHashModelEx} interface, then all names it retrieves through a call
 * to {@link TemplateHashModelEx#keys()} method are returned as well. The method returns a new Set object on each
 * call that is completely disconnected from the Environment. That is, modifying the set will have no effect on the
 * Environment object.
