public ProductDerivations()

Method Detail

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 key, 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 key and, if a value is found, using the prefix of that key. Otherwise, it uses the first registered prefix.
