FastCat is a streamlined and faster version of StringBuffer/StringBuilder that's more efficient as it doesn't allocate a buffer until the last minute and then only allocates it at the exact required size. It is used when writing your own Java programs. Its operation is very similar to that of StringBuilder, so the Javadoc should be all you need.

  • FastCat is safe in case of null value. If you pass a null value or a zero-length string to any of the .append methods, it does nothing.
  • FastCat is not suitable if you're appending one character at a time to your FastCat. For this kind of application, you're better off using the traditional StringBuilder.
  • FastCat operates very quickly with minimal RAM usage if you can roughly predict how many blocks you are going to add, but only have a vague idea of the total final size.
  • By minimizing RAM usage, your garbage collection occurs less frequently, which speeds it up.

The basic idea of FastCat is that you estimate how many blocks you're concatenating, not the length of the output. This means you can simplify your application code. You don't need to explicitly avoid adding nulls, an error that can go unnoticed in testing with StringBuilder as it may only occur sporadically. FastCat has demonstrated a 10% acceleration when HTMLMacros application started using it.

In summary, FastCat is a valuable tool for Java developers seeking to optimize their programs while minimizing RAM usage. Its efficiency and ease of use make it an ideal choice for projects requiring a large amount of string concatenation.
