AvoidStringBufferField


AvoidStringBufferField
[
			StringBuffers can grow quite a lot, and so may become a source of memory leak (if the owning class has a long life time).
		
    
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    
//FieldDeclaration/Type/ReferenceType/ClassOrInterfaceType[@Image = 'StringBuffer']

			
  
		    
		    
	    
	    
        
        
        Example:
            
                    

class Foo {
	private StringBuffer memoryLeak;
}
