/**
|
|
* cairo_hash_entry_t:
|
|
*
|
|
* A #cairo_hash_entry_t contains both a key and a value for
|
|
* cairo_hash_table_t. User-derived types for cairo_hash_entry_t must
|
|
* be type-compatible with this structure (eg. they must have an
|
|
* unsigned long as the first parameter. The easiest way to get this
|
|
* is to use:
|
|
*
|
|
* typedef _my_entry {
|
|
* cairo_hash_entry_t base;
|
|
* ... Remainder of key and value fields here ..
|
|
* } my_entry_t;
|
|
*
|
|
* which then allows a pointer to my_entry_t to be passed to any of
|
|
* the cairo_hash_table functions as follows without requiring a cast:
|
|
*
|
|
* _cairo_hash_table_insert (hash_table, &my_entry->base);
|
|
*
|
|
* IMPORTANT: The caller is reponsible for initializing
|
|
* my_entry->base.hash with a hash code derived from the key. The
|
|
* essential property of the hash code is that keys_equal must never
|
|
* return TRUE for two keys that have different hashes. The best hash
|
|
* code will reduce the frequency of two keys with the same code for
|
|
* which keys_equal returns FALSE.
|
|
*
|
|
* Which parts of the entry make up the "key" and which part make up
|
|
* the value are entirely up to the caller, (as determined by the
|
|
* computation going into base.hash as well as the keys_equal
|
|
* function). A few of the cairo_hash_table functions accept an entry
|
|
* which will be used exclusively as a "key", (indicated by a
|
|
* parameter name of key). In these cases, the value-related fields of
|
|
* the entry need not be initialized if so desired.
