Class FsfLicenseDataParser

java.lang.Object
org.spdx.licenselistpublisher.licensegenerator.FsfLicenseDataParser
public class FsfLicenseDataParser extends Object
Singleton class which returns information maintained by the Free Software Foundation The default behavior is to pull the FSF data from https://spdx.github.io/fsf-api/licenses-full.json If the URL is not accessible, the file resources/licenses-full.json in the same path as the .jar file will be used. If the local file can not be found, then a properties file resources/licenses-full.json will be used. There are two properties that can be used to control where the JSON file is loaded from: LocalFsfFreeJson - if set to true, then use the local file or, if the local file is not found, the resource files and don't access the file from the github.io page FsfFreeJsonUrl - the URL to pull the JSON file from. If both LocalFsfFreeJson and FsfFreeJsonUrl are specified, then the LocalFsfFreeJson takes precedence and the local resource file will be used. NOTE: This is currently using a non authoritative data source TODO: Update the class to use an official FSF data source once available
