I have a static method that needs to load a rather large file once (this
method is in a third party library, so refactoring is not an option):
public class Foo
{
/**
* Call once before using Foo to load
**/
public static void init(String filename);
...
}
My config xmlrules file looks like:
<pattern value="example/foo">
<!-- static initializer, somewhat-->
<object-create-rule classname="Foo"/>
<call-method-rule methodname="init"
paramcount="1" />
<call-param-rule paramnumber='0' attrname='file'/>
</pattern>
And my configuration file looks like:
<example>
<foo file="path.to.foo.initialization.file"/>
</example>
The object-create-rule is superflous to some extent, b/c the init call
is on a static. However, from my limited understanding of Digester, I
need to have an object
on the stack of type Foo in order to call a method on it (even if it is
static).
The above works, it's just that the object created is just thrown away,
as it is not needed, since the other method that I use on Foo is also
static. I was just wondering if there was another way to do this, I can
envision something like:
<call-static-method-rule methodname="init" paramcount="1"
classname="Foo"/>
<call-param-rule paramnumber='0' attrname='file'/>
Thanks,
Grant

Sorry, Grant, but I don't understand. Perhaps you could provide some
code demonstrating what you're trying to achieve?
