java.lang.Object
  freemarker.template.utility.ObjectConstructor

All Implemented Interfaces:

TemplateMethodModel, TemplateMethodModelEx, TemplateModel

public class ObjectConstructor
extends java.lang.Object
implements TemplateMethodModelEx

An object that you can make available in a template to instantiate arbitrary beans-wrapped objects in a template. Beware of this class's security implications. It allows the instantiation of arbitrary objects and invoking methods on them. Usage is something like:

myDataModel.put("objectConstructor", new ObjectConstructor());

And then from your FTL code:

<#assign aList = objectConstructor("java.util.ArrayList", 100)>

exec in interface TemplateMethodModel

Specified by:

exec in interface TemplateMethodModelEx

Parameters:

args - a List of TemplateModel objects containing the values of the arguments passed to the method. If the implementation wishes to operate on POJOs that might be underlying the models, it can use the static utility methods in the DeepUnwrap class to easily obtain them.

the return value of the method, or null. If the returned value does not implement TemplateModel, it will be automatically wrapped using the environment object wrapper.

Throws:

TemplateModelException
