Method Detail

exec
public Object exec(List arguments) throws TemplateModelException
Invokes the method, passing it the arguments from the list.- Specified by:
execin interfaceTemplateMethodModel- Specified by:
execin interfaceTemplateMethodModelEx- Parameters:
arguments- aListofTemplateModel-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 theDeepUnwrapclass 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 originalTemplateModelvalue 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:TemplateSequenceModelRetrieves the i-th template model in this sequence.- Specified by:
getin interfaceTemplateSequenceModel- Returns:
- the item at the specified index, or
nullif the index is out of bounds. Note that anullvalue 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:
sizein interfaceTemplateSequenceModel- Returns:
- the number of items in the list.
- Throws:
TemplateModelException
-
explainTypeError
public Object[] explainTypeError(Class[] expectedClasses)
Implementation of experimental interface; don't use it, no backward compatibility guarantee!- Specified by:
