FinalizeDoesNotCallSuperFinalize


FinalizeDoesNotCallSuperFinalize
If the finalize() is implemented, its last action should be to call super.finalize.
       
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    

//MethodDeclaration[MethodDeclarator[@Image='finalize'][not(FormalParameters/*)]]
   /Block
      /BlockStatement[last()]
      [not(Statement/StatementExpression/PrimaryExpression/PrimaryPrefix[@Image='finalize'])]
      [not(Statement/TryStatement/FinallyStatement
       /Block/BlockStatement/Statement/StatementExpression
        /PrimaryExpression/PrimaryPrefix[@Image='finalize'])]

                
  
		    
		    
	    
	    
        
        
        Example:
            
                    

public class Foo {
   protected void finalize() {
       something();
       // neglected to call super.finalize()
   }
}
