ShortVariable


ShortVariable
Detects when a field, local, or parameter has a very short name.
    
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                      
//VariableDeclaratorId[string-length(@Image) &lt; 3]
 [not(ancestor::ForInit)]
 [not((ancestor::FormalParameter) and (ancestor::TryStatement))]
                  
              
  
		    
		    
	    
	    
        
        
        Example:
            
                    

public class Something {
  private int q = 15; // VIOLATION - Field
  public static void main( String as[] ) {  // VIOLATION - Formal
    int r = 20 + q; // VIOLATION - Local
    for (int i = 0; i < 10; i++) { // Not a Violation (inside FOR)
      r += q;
    }
  }
}
