/** * UHashtable stores key-value pairs and does moderately fast lookup * based on keys. It provides a good tradeoff between access time and * storage space. As elements are added to it, it grows to accommodate * them. By default, the table never shrinks, even if all elements * are removed from it. * * Keys and values are stored as void* pointers. These void* pointers * may be actual pointers to strings, objects, or any other structure * in memory, or they may simply be integral values cast to void*. * UHashtable doesn't care and manipulates them via user-supplied * functions. These functions hash keys, compare keys, delete keys, * and delete values. Some function pointers are optional (may be * NULL); others must be supplied. Several prebuilt functions exist * to handle common key types. * * UHashtable ownership of keys and values is flexible, and controlled * by whether or not the key deleter and value deleter functions are * set. If a void* key is actually a pointer to a deletable object, * then UHashtable can be made to delete that object by setting the * key deleter function pointer to a non-NULL value. If this is done, * then keys passed to uhash_put() are owned by the hashtable and will * be deleted by it at some point, either as keys are replaced, or * when uhash_close() is finally called. The same is true of values * and the value deleter function pointer. Keys passed to methods * other than uhash_put() are never owned by the hashtable. * * NULL values are not allowed. uhash_get() returns NULL to indicate * a key that is not in the table, and having a NULL value in the * table would generate an ambiguous result. If a key and a NULL * value is passed to uhash_put(), this has the effect of doing a * uhash_remove() on that key. This keeps uhash_get(), uhash_count(), * and uhash_nextElement() consistent with one another. * * Keys and values can be integers. * Functions that work with an integer key have an "i" prefix. * Functions that work with an integer value have an "i" suffix. * As with putting a NULL value pointer, putting a zero value integer removes the item. * Except, there are pairs of functions that allow setting zero values * and fetching (value, found) pairs. * * To see everything in a hashtable, use uhash_nextElement() to * iterate through its contents. Each call to this function returns a * UHashElement pointer. A hash element contains a key, value, and * hashcode. During iteration an element may be deleted by calling * uhash_removeElement(); iteration may safely continue thereafter. * The uhash_remove() function may also be safely called in * mid-iteration. If uhash_put() is called during iteration, * the iteration is still guaranteed to terminate reasonably, but * there is no guarantee that every element will be returned or that * some won't be returned more than once. * * Under no circumstances should the UHashElement returned by * uhash_nextElement be modified directly. * * By default, the hashtable grows when necessary, but never shrinks, * even if all items are removed. For most applications this is * optimal. However, in a highly dynamic usage where memory is at a * premium, the table can be set to both grow and shrink by calling * uhash_setResizePolicy() with the policy U_GROW_AND_SHRINK. In a * situation where memory is critical and the client wants a table * that does not grow at all, the constant U_FIXED can be used.
