public final class SimpleMethodModel extends java.lang.Object implements TemplateMethodModelEx, TemplateSequenceModel, freemarker.core._UnexpectedTypeErrorExplainerTemplateModel
A class that will wrap a reflected method call into aTemplateMethodModel
interface. It is used byBeanModel
to wrap reflected method calls for non-overloaded methods.

Method Detail

exec
public java.lang.Object exec(java.util.List arguments) throws TemplateModelException
Invokes the method, passing it the arguments from the list.- Specified by:
exec
in interfaceTemplateMethodModel
- Specified by:
exec
in interfaceTemplateMethodModelEx
- Parameters:
arguments
- aList
ofTemplateModel
-s, containing the arguments passed to the method. If the implementation absolutely wants to operate on POJOs, it can use the static utility methods in theDeepUnwrap
class to easily obtain them. However, unwrapping is not always possible (or not perfectly), and isn't always efficient, so it's recommended to use the originalTemplateModel
value as much as possible.- Returns:
- the return value of the method, or
null
. If the returned value does not implementTemplateModel
, it will be automatically wrapped using theenvironment's object wrapper
. - Throws:
TemplateModelException
-
get
public TemplateModel get(int index) throws TemplateModelException
Description copied from interface:TemplateSequenceModel
Retrieves the i-th template model in this sequence.- Specified by:
get
in interfaceTemplateSequenceModel
- Returns:
- the item at the specified index, or
null
if the index is out of bounds. Note that anull
value is interpreted by FreeMarker as "variable does not exist", and accessing a missing variables is usually considered as an error in the FreeMarker Template Language, so the usage of a bad index will not remain hidden, unless the default value for that case was also specified in the template. - Throws:
TemplateModelException
-
size
public int size() throws TemplateModelException
- Specified by:
size
in interfaceTemplateSequenceModel
- Returns:
- the number of items in the list.
- Throws:
TemplateModelException
-
toString
public java.lang.String toString()
- Overrides:
toString
in classjava.lang.Object

explainTypeError
public java.lang.Object[] explainTypeError(java.lang.Class[] expectedClasses)
Implementation of experimental interface; don't use it, no backward compatibility guarantee!- Specified by:
