String matching in java -


I am currently struggling to find partial matches with my "Dirty Words" filter.

Example: If I 

  replace the personal string string with the word (string word, string input) {/ p> 
  for this method  
  Pattern Legacy Pattern = Pattern.compile (word, Pattern.CASE_INSENSITIVE); Matcher matcher = Legacy Pattern.matcher (input); Stringbilder return string = new stringbilder (); Int index = 0; While (matcher.find ()) {returnString.append (input.substring (index, matcher.start ())); For (int i = 0; i & lt; word.length () - 1; i ++) {returnString.append ('*'); } ReturnString.append (word.substring (word.length () - 1)); Index = matcher.end (); } If (index  
 
 me p *  sing p  * sp ** sed ** s 
 
 when I really want "passing pass passed" Anyone can know how to avoid partial matching with this method? Any help will be great thanks!

Will tell you in the right direction.

You want to use the word limit in your pattern: 

  pattern p = pattern.compile ("\\ bword \\" ", Pattern. CASEX ANSIVIE);

Note, though it is still problematic ( As it is always that filth is filtered out). A "non-word character" defining the limit is not included in [0-9A-Za-z _]

For example, _ass will not match.

You also have the problem of the derivative derivative ... where the word says, "hole", "wipe", etc. < / P>

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
