I have a problem with deferred binding or perhaps GWT's static analysis not
behaving quite the way I thought it did. I have a class that looks like this:
public abstract class Mode
{
public abstract boolean isDebug();
}
and I have two subclasses, one with a hard-coded value of false for isDebug()
and the other has a hard-coded value of true. I then have appropriate gwt.xml
directives that introduce a new permutation and select the appropriate
implementation of Mode.
This all works as expected. My problem is this...if I use a central class to
record whether we're in debug mode or not like this:
public class Central
{
private static final Mode mode = GWT.create(Mode.class);
public static boolean isDebug() { return mode.isDebug(); }
}
and then I have a class that uses this value like this:
public class Foo
{
public void doSomething()
{
if (Central.isDebug())
Log.debug("Here I am");
}
}
then what I find is that in the permutation where isDebug() returns false, the Log.debug("Here
I am") line does not get run, but the text string "Here I am" is in the output
javascript file for *all* permutations. I was expecting it only to be in the debug permutations.
If I change the Foo class like this:
public class Foo
{
private static final Mode mode = GWT.create(Mode.class);
public void doSomething()
{
if (mode.isDebug())
Log.debug("Here I am");
}
}
then I find that the "Here I am" string is only in the debug permutations.
Am I expecting too much of the static analysis GWT does at compile time? Or
have I missed something?
Thanks,
Paul
