Method Detail

load

public java.lang.Object load(Engine engine,
                             java.util.List args)
                      throws java.lang.Exception

Specified by:

load in interface DataLoader

args - Arguments that the caller specifies for this directive call. Not null. The implementation should check if it understands all arguments, and it should throw java.lang.IllegalArgumentException if it doesn't.

Returns:

The object that will be accessed in FreeMarker templates. The object can be of any type. FreeMarker will wrap the object so that it is visible as an FTL variable. However, if the object implements freemarker.template.TemplateModel, then it will not be wrapped, as it is already an FTL variable.

Throws:

java.lang.Exception

load

public freemarker.template.TemplateNodeModel load(Engine engine,
                                                  java.util.List args,
                                                  org.w3c.dom.Document preLoadedDoc)

Throws:

java.lang.Exception

isOptionName

public static boolean isOptionName(java.lang.String optionName)

Checks if the string is a valid xml data loader option name. Options names are the keys in the hash pased as the 2nd argument to the xml data loader.
