InsufficientStringBufferDeclaration


InsufficientStringBufferDeclaration
Failing to pre-size a StringBuffer properly could cause it to re-size many times
during runtime. This rule checks the characters that are actually passed into
StringBuffer.append(), but represents a best guess "worst case" scenario. An
empty StringBuffer constructor initializes the object to 16 characters. This default
is assumed if the length of the constructor can not be determined.
    
		
		
		    
		    
    		    
    		    
    		    

    		    This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.strings.InsufficientStringBufferDeclaration
    		    
		    
	    
	    
        
        
        Example:
            
                    

public class Foo {
    void bar() {
        StringBuffer bad = new StringBuffer();
        bad.append("This is a long string, will exceed the default 16 characters");//bad
        StringBuffer good = new StringBuffer(41);
        good.append("This is a long string, which is pre-sized");//good
    }
}
