225 /* data structures for hashtables ********************************************
228 All utf-symbols, javastrings and classes are stored in global hashtables,
229 so every symbol exists only once. Equal symbols have identical pointers.
230 The functions for adding hashtable elements search the table for the
231 element with the specified name/text and return it on success. Otherwise a
232 new hashtable element is created.
234 The hashtables use external linking for handling collisions. The hashtable
235 structure contains a pointer <ptr> to the array of hashtable slots. The
236 number of hashtable slots and therefore the size of this array is specified
237 by the element <size> of hashtable structure. <entries> contains the number
238 of all hashtable elements stored in the table, including those in the
240 The hashtable element structures (utf, literalstring, classinfo) contain
241 both a pointer to the next hashtable element as a link for the external hash
242 chain and the key of the element. The key is computed from the text of
243 the string or the classname by using up to 8 characters.
245 If the number of entries in the hashtable exceeds twice the size of the
246 hashtableslot-array it is supposed that the average length of the
247 external chains has reached a value beyond 2. Therefore the functions for
248 adding hashtable elements (utf_new, class_new, literalstring_new) double
249 the hashtableslot-array. In this restructuring process all elements have
250 to be inserted into the new hashtable and new external chains must be built.

694 The vtbl has a bidirectional layout with open ends at both sides.
695 interfacetablelength gives the number of entries of the interface table at
696 the start of the vftbl. The vftbl pointer points to &interfacetable[0].
697 vftbllength gives the number of entries of table at the end of the vftbl.
699 runtime type check (checkcast):
701 Different methods are used for runtime type check depending on the
702 argument of checkcast/instanceof.
704 A check against a class is implemented via relative numbering on the class
705 hierachy tree. The tree is numbered in a depth first traversal setting
706 the base field and the diff field. The diff field gets the result of
707 (high - base) so that a range check can be implemented by an unsigned
708 compare. A sub type test is done by checking the inclusion of base of
709 the sub class in the range of the superclass.
711 A check against an interface is implemented via the interfacevftbl. If the
712 interfacevftbl contains a nonnull value a class is a subclass of this
717 Like standard virtual methods interface methods are called using
718 virtual function tables. All interfaces are numbered sequentially
719 (starting with zero). For each class there exist an interface table
720 of virtual function tables for each implemented interface. The length
721 of the interface table is determined by the highest number of an
722 implemented interface.
724 The following example assumes a class which implements interface 0 and 3:
726 interfacetablelength = 4
