I have a groovy class that has the ability to write its output to a StringWriter
- (via a setStringWriter
method).
In java I would use the following code:
filter.setStringWriter(new StringWriter(){
@Override
public void write(String string){
// do something with the string
}
});
For Groovy I'm told to use a closure, I've tried the following with no luck:
def s = {String line -> print line} as StringWriter
filter.setStringWriter(s)
or
filter.setStringWriter{String line -> print line}
How do I go about doing this, or is it even possible?
The following link gives a clue, although it only mentions interfaces.
The following works with Groovy 1.6.1:
def s = [ write: { String line -> print line} ] as StringWriter
filter.setStringWriter(s)
