Method Summary |
java.lang.Object |
exec(java.util.List arguments)
Executes a method call. |
exec
java.lang.Object exec(java.util.List arguments)
throws TemplateModelException
- Executes a method call. All arguments passed to the method call are
coerced to strings before being passed, if the FreeMarker rules allow
the coercion. If some of the passed arguments can not be coerced to a
string, an exception will be raised in the engine and the method will
not be called. If your method would like to act on actual data model
objects instead of on their string representations, implement the
TemplateMethodModelEx
instead.
- Parameters:
arguments
- a List of String objects
containing the values of the arguments passed to the method.
- Returns:
- 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
