How to avoid MissingPropertyException

Question

If an object does not have a property and I am accessing the property, we get a MissingPropertyException. Can I do something similar to safe null (?.

Answer 1

One option would be:

def result = obj.hasProperty( 'b' ) ? obj.b : null

Which would return null if the object doesn't have the property...

Another would be to add propertyMissing to your class like so:

def propertyMissing( name ) {
  null
}

This means that any missing properties would just result in null.
