    • ProductDerivations

      public ProductDerivations()

  • Method Details

    • getProductDerivations

      public static ProductDerivation[] getProductDerivations()
      Return all the product derivations registered in the current classloader

    • getConfigurationPrefixes

      public static String[] getConfigurationPrefixes()
      Return the recognized prefixes for configuration properties.

    • getConfigurationKey

      public static String getConfigurationKey(String partialKey, Map map)
      Determine the full key name for partialKey, given the registered prefixes and the entries in map. This method computes the appropriate configuration prefix to use by looking through map for a key starting with any of the known configuration prefixes and ending with partialKey and, if a value is found, using the prefix of that key. Otherwise, it uses the first registered prefix. The given partialKey is first tested for containment in the given map without any prefix.

    • beforeConfigurationConstruct

      public static void beforeConfigurationConstruct(ConfigurationProvider cp)
      Apply ProductDerivation.beforeConfigurationConstruct(org.apache.openjpa.lib.conf.ConfigurationProvider) callbacks to the the given instance. Exceptions other than fatal BootstrapException are swallowed.

    • beforeConfigurationLoad

      public static void beforeConfigurationLoad(Configuration conf)
      Apply ProductDerivation.beforeConfigurationLoad(org.apache.openjpa.lib.conf.Configuration) callbacks to the the given instance. Exceptions other than fatal BootstrapException are swallowed.

    • afterSpecificationSet

      public static void afterSpecificationSet(Configuration conf)
      Apply ProductDerivation.afterSpecificationSet(org.apache.openjpa.lib.conf.Configuration) callbacks to the the given instance. Exceptions other than fatal BootstrapException are swallowed.

    • beforeClose

      public static void beforeClose(Configuration conf)
      Called as the first step of a Configuration's close() method. Exceptions are swallowed.

    • load

      public static ConfigurationProvider load(String resource, String anchor, ClassLoader loader)
      Load the given given resource, or return false if it is not a resource this provider understands. The given class loader may be null.
      Parameters:
      anchor - optional named anchor within a multiple-configuration resource

    • load

      public static ConfigurationProvider load(File file, String anchor, ClassLoader loader)
      Load given file, or return false if it is not a file this provider understands.
      Parameters:
      anchor - optional named anchor within a multiple-configuration file

    • loadDefaults

      public static ConfigurationProvider loadDefaults(ClassLoader loader)
      Return a ConfigurationProvider that has parsed system defaults.

    • loadGlobals

      public static ConfigurationProvider loadGlobals(ClassLoader loader)
      Return a ConfigurationProvider that has parsed system globals.

    • getFullyQualifiedAnchorsInPropertiesLocation

      public static List<String> getFullyQualifiedAnchorsInPropertiesLocation(String propertiesLocation)
      Return a List of all the fully-qualified anchors specified in propertiesLocation. The return values must be used in conjunction with propertiesLocation. If there are no product derivations or if no product derivations could find anchors, this returns an empty list.

      1.1.0

    • getSupportedQueryHints

      public static Set<String> getSupportedQueryHints()

    • main

      public static void main(String[] args)
      Prints product derivation information.
