Usage

From source file:ai.general.interbot.ConfigFiles.java

/**
 * Saves a configuration file. The filename should specify only the configuration filename.
 * The file will be saved to the configuration file directory that is appropriate for the
 * current context./* w ww .j a  v  a 2s . c om*/
 *
 * The configuration object will be saved in JSON format. The configuration object must be a
 * POJO class that is serializable into JSON.
 *
 * If the .json extension is not specified in the filename, it will be appended to the filename.
 *
 * @param filename The name of the configuration file, excluding extension and directory.
 * @param configuration The object representing the configuration to be saved.
 * @return True if the file was successfully saved.
