Each one returns a function that takes as parameters a reference to a hash of defined classes , and the atom name itself 每個原子都返回一個函數(shù),該函數(shù)將參數(shù)作為對已定義類的散列和原子名本身的引用。
This is because the wordnet xml server approach takes advantage of specialized hashing and indexing used by the wordnet database , rather than shredding that into a more general rdf database 這是因為wordnet xml服務(wù)器利用了wordnet數(shù)據(jù)庫所用的專用散列和索引,而不是查詢一般的rdf數(shù)據(jù)庫。
Unfortunately , we have to get the address exactly right , down to the byte , or the program will crash . coming up with the right address using the trial and error approach may take a while . to make things easier , we can insert lots of null operations in front of the shell code 但是,問題的大部分是因為數(shù)據(jù)很可能有統(tǒng)計偏差,因此大量精力花在了使用七個密碼散列和一個相當(dāng)慢(但非常好)的偽隨機數(shù)發(fā)生器來消除此類問題上。
