The template + * parameters relates to the kind of key used and how duplicates are + * treated. + * + * \#define KAVL_EQUAL_ALLOWED + * Define this to tell us that equal keys are allowed. + * Then Equal keys will be put in a list pointed to by KAVLNODE::pList. + * This is by default not defined. + * + * \#define KAVL_CHECK_FOR_EQUAL_INSERT + * Define this to enable insert check for equal nodes. + * This is by default not defined. + * + * \#define KAVL_MAX_STACK + * Use this to specify the max number of stack entries the stack will use when + * inserting and removing nodes from the tree. The size should be something like + * log2() + 3 + * Must be defined. + * + * \#define KAVL_RANGE + * Define this to enable key ranges. + * + * \#define KAVL_OFFSET + * Define this to link the tree together using self relative offset + * instead of memory pointers, thus making the entire tree relocatable + * provided all the nodes - including the root node variable - are moved + * the exact same distance. + * + * \#define KAVL_LOOKTHRU + * Define this to employ a lookthru cache (direct) to speed up lookup for + * some usage patterns. The value should be the number of members of the + * array. + * + * \#define KAVL_LOOKTHRU_HASH(Key) + * Define this to specify a more efficient translation of the key into + * a lookthru array index. The default is key % size. + * For some key types this is required as the default will not compile. + * + * \#define KAVL_LOCKED + * Define this if you wish for the tree to be locked via the + * KAVL_WRITE_LOCK, KAVL_WRITE_UNLOCK, KAVL_READ_LOCK and + * KAVL_READ_UNLOCK macros. If not defined the tree will not be subject + * do any kind of locking and the problem of concurrency is left the user. + * + * \#define KAVL_WRITE_LOCK(pRoot) + * Lock the tree for writing. + * + * \#define KAVL_WRITE_UNLOCK(pRoot) + * Counteracts KAVL_WRITE_LOCK. + * + * \#define KAVL_READ_LOCK(pRoot) + * Lock the tree for reading. + * + * \#define KAVL_READ_UNLOCK(pRoot) + * Counteracts KAVL_READ_LOCK. + * + * \#define KAVLKEY + * Define this to the name of the AVL key type. + * + * \#define KAVL_STD_KEY_COMP + * Define this to use the standard key compare macros. If not set all the + * compare operations for KAVLKEY have to be defined: KAVL_G, KAVL_E, KAVL_NE, + * KAVL_R_IS_IDENTICAL, KAVL_R_IS_INTERSECTING and KAVL_R_IS_IN_RANGE. The + * latter three are only required when KAVL_RANGE is defined. + * + * \#define KAVLNODE + * Define this to the name (typedef) of the AVL node structure. This + * structure must have a mpLeft, mpRight, mKey and mHeight member. + * If KAVL_RANGE is defined a mKeyLast is also required. + * If KAVL_EQUAL_ALLOWED is defined a mpList member is required. + * It's possible to use other member names by redefining the names. + * + * \#define KAVLTREEPTR + * Define this to the name (typedef) of the tree pointer type. This is + * required when KAVL_OFFSET is defined. When not defined it defaults + * to KAVLNODE *. + * + * \#define KAVLROOT + * Define this to the name (typedef) of the AVL root structure. This + * is optional. However, if specified it must at least have a mpRoot + * member of KAVLTREEPTR type. If KAVL_LOOKTHRU is non-zero a + * maLookthru[KAVL_LOOKTHRU] member of the KAVLTREEPTR type is also + * required. + * + * \#define KAVL_FN + * Use this to alter the names of the AVL functions. + * Must be defined. + * + * \#define KAVL_TYPE(prefix, name) + * Use this to make external type names and unique. The prefix may be empty. + * Must be defined. + * + * \#define KAVL_INT(name) + * Use this to make internal type names and unique. The prefix may be empty. + * Must be defined. + * + * \#define KAVL_DECL(rettype) + * Function declaration macro that should be set according to the scope + * the instantiated template should have. For instance an inlined scope + * (private or public) should K_DECL_INLINE(rettype) here. + * + * This version of the kAVL tree offers the option of inlining the entire + * implementation. This depends on the compiler doing a decent job in both + * making use of the inlined code and to eliminate const variables. + */ + + +/******************************************************************************* +* Internal Functions * +*******************************************************************************/ +#include +#include +#include + + +/******************************************************************************* +* Defined Constants And Macros * +*******************************************************************************/ +#define KAVL_HEIGHTOF(pNode) ((KU8)((pNode) != NULL ?
