Frances, I have two implementations of INode, record MapNode and record VectorNode, which are defined in other files.
Also, I get a syntax method when calling new-node without the leading dot when using defprotocol: java.lang.IllegalArgumentException: No single method: newNode of interface: aatree.nodes.INode found for function: newNode of protocol: INode, compiling:(aatree/nodes.clj:51:7) On Tuesday, September 8, 2015 at 3:29:38 PM UTC-4, Francis Avila wrote: > > I don't quite understand why you are not calling the Protocol method as a > function, i.e. > > (new-node this t-2 lev l r c) > > (no leading dot on new-node). > > I also don't see anything which actually *implements* INode. > > Note that the meaning of "method" in "Protocol method" is not the same as > in "Java method": i.e. these are not Java methods called via Java interop, > although protocol implementations may create java methods on the class that > implements them in some cases (i.e. inline implementations using deftype or > defrecord) or a Java class may implement the protocol via the > auto-generated interface of the same name.
