public class ConsecutiveLiteralAppendsRule extends AbstractJavaRule
This rule finds concurrent calls to StringBuffer/Builder.append where String literals are used It would be much better to make these calls using one call to.append
Example:
StringBuilder buf = new StringBuilder(); buf.append("Hello"); buf.append(" ").append("World");
This would be more eloquently put as:
StringBuilder buf = new StringBuilder(); buf.append("Hello World");
The rule takes one parameter, threshold, which defines the lower limit of consecutive appends before a violation is created. The default is 1.
