UseStringBufferLength
Use StringBuffer.length() to determine StringBuffer length rather than using StringBuffer.toString().equals("")
          or StringBuffer.toString().length() ==.
      

		
		
		    
		    
    		    
    		    
    		    

    		    
This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.strings.UseStringBufferLength
    		    
		    
	    
	    
        
        
        
Example:
            
    
                
  
public class Foo {
 void bar() {
  StringBuffer sb = new StringBuffer();
  // this is bad
  if(sb.toString().equals("")) {}
  // this is good
  if(sb.length() == 0) {}
 }
}
