Features

Pablo is a Java library that provides APIs to access and utilize properties that can change dynamically at runtime. It includes the following features:

Dynamic properties

Pablo provides classes that represent dynamic properties where the values are of specific types and can change at runtime.

Instead of writing code like this:

  String prop = System.getProperty("myProperty");
  try {
      int x = Integer.parseInt(prop);
      if (x > 0) {
          // ...
      }
  } catch (NumberFormatException e) {
      // handle format issues
  }

A polling framework for dynamic changing configuration sources

Out of the box, in a fixed interval, Pablo will load configuration sources from a local file on classpath as well as a set of URLs defined in a system property.

You can define your own configuration source and poll scheduler by extending appropriate interface/class.
