Class SimpleMethodModel

java.lang.Object

freemarker.ext.beans.SimpleMethodModel

All Implemented Interfaces:

freemarker.core._UnexpectedTypeErrorExplainerTemplateModel, TemplateMethodModel, TemplateMethodModelEx, TemplateModel, TemplateSequenceModel

public final class SimpleMethodModel
extends java.lang.Object
implements TemplateMethodModelEx, TemplateSequenceModel, freemarker.core._UnexpectedTypeErrorExplainerTemplateModel

A class that will wrap a reflected method call into a TemplateMethodModel interface. It is used by BeanModel 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 interface TemplateMethodModel

Specified by:

exec in interface TemplateMethodModelEx

Parameters:

arguments - a List of TemplateModel-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 the DeepUnwrap 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 original TemplateModel value as much as possible.

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'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 interface TemplateSequenceModel

Returns:

the item at the specified index, or null if the index is out of bounds. Note that a null 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 interface TemplateSequenceModel

Returns:

the number of items in the list.

Throws:

TemplateModelException

toString

public java.lang.String toString()

Overrides:

toString in class java.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:

explainTypeError in interface freemarker.core._UnexpectedTypeErrorExplainerTemplateModel

getMember

protected java.lang.reflect.Member getMember()
