Overriding the Java toString method using For loop

This solution uses a combination of reflection, constants and regular expressions to build a meaningful toString output:

private String TO_STRING_FIELDS = "email isPKI isTrustedRoot isITU_TX509 caName"

    @Override public String toString() {
        try {
            StringBuilder result = new StringBuilder();
            //String newLine = System.getProperty("line.separator");
            String[] fieldList = TO_STRING_FIELDS.split( "[\\s,]+");
            Field curField = null;
            for (String f : fieldList) {
                curField = this.getClass().getDeclaredField(f);
                result.append("  " + f);
                result.append(": ");
                //requires access to private field:
                result.append( curField.get(this) );
            }
        } catch (Exception e) {
            System.out.println("Error in toString for class: " + this.getClass().getName() + "\n" + e.getMessage());
        }

        return null;
    }

Refurbishing a Morgan 30

Hull Preparation and Painting

After all the work I did restoring my Flying Scot this summer, I can imagine what a labor (of love) this Morgan 30 refurb was. There are a lot of great tips and experience to be gleaned from his notes.

as3corelib Contains Crypto Utils for FLEX MD5 Hash

I needed to store MD5 hashed passwords in the database and was delighted to find the as3corelib already contains the necessary libraries.  While there are many more features, I only needed the MD5 Hash function so I only copied in the com.adobe.crypto.MD5 and com.adobe.utils.* files.  With the .as files added to my Flex project, hashing the password was a simple as calling:

    MD5.hash( passwordComp.getPassword() );

 

I verified that it returns the same hash as the MySQL MD5 function

UPDATE user_table SET password = MD5(‘change_me’) WHERE username = ‘sandman’
