Apron — Advanced Properties

A better API for accessing Java .properties files

Apron is a library for providing a developer-friendly way for reading and writing Java .properties files. In particular it supports writing changes to a .properties file in the least intrusive way possible.

Short Usage

 1## Apron example ##

 3# The appName can be changed in-app
 4appName     = My shiny app
 5
 6# The default port is 5040.
 7# Change it if necessary
 8#listenPort  = 5040
 9
10# This description is only visible in
11# the "About" dialog.
12description = Only a \
13              test project

 2
 3
 4final File file= new File("application.properties");
 5final PropertyFile propertyFile= PropertyFile.from(file);
 6
 7// Read the value of the key "appName"
 8final String appName= propertyFile.get("appName");
 9
10// Change the value of "appName" to a new value
11propertyFile.set("appName", "My brilliant app");
12
13// Write the PropertyFile back to file
14// by only updating the modified values
15propertyFile.update(file);
16}
  1. Read the result
