A stirrer for a planetary mixer has an upper central hub with two outwardly extending horizontal arms and two helical stirring elements, one depending from each arm. According to the presently preferred embodiments, the cross sectional area of the stirring elements is large enough that no bottom crossbar is necessary. The pitch angle of each stirring element is preferably constant from top to bottom. The leading side of the stirring elements has a flat surface whereas the trailing side is curved. The flat surface increases in size moving toward the bottom of the stirring element.

The method of claim 2, further comprising the steps of: in response to processing a method invocation statement in the program that invokes an interface virtual method in the set S corresponding to the given entry, generating a method invocation routine that: stores the identifier assigned to the signature of the interface virtual method VM in a predetermined storage location, and uses the pointer stored in the given entry corresponding to interface virtual method to transfer control to one of the implementation of the interface virtual method VM and the implementation of the conflict resolution routine. 4. The method of claim 3, wherein the conflict resolution routine provides, for each given interface method of the plurality of interface methods in the set S corresponding to the given entry, an association between the identifier assigned to the signature of the given interface method and a pointer to the implementation of the given interface method. 5. The method of claim 4, wherein the conflict resolution routine loads the identifier stored in the predetermined storage location, searches to find a match between the loaded identifier and one of the identifiers assigned to the signature of the plurality of interface methods in the set S corresponding to the given entry, and uses the pointer associated with the matching one identifier to transfer control to the implementation of the interface method corresponding to the matching one identifier. 6. The method of claim 5, wherein the predetermined storage location comprises a scratch register in a register file of a computer processing apparatus that is executing the method invocation routine. 7. The method of claim 4, wherein said pointer to the implementation of the given interface method comprises an offset into a virtual method table of the class of the this parameter to the interface method being invoked.
