Parameters:

name -

setup -

getConfigPropertyAsString

public static String getConfigPropertyAsString(String propertyKey,
                                               Map overrides)

getConfigPropertyAsString

public static String getConfigPropertyAsString(String propertyKey,
                                               Map overrides,
                                               String defaultValue)

Check the provided map for an object with the given key. If that object is not available, check the System properties. If it is not available from either location, return the default value.

Parameters:

propertyKey -

map -

defaultValue -

Returns:

hasConfigProperty

public static boolean hasConfigProperty(String propertyKey,
                                        Map overrides)

getEntityManagerSetupImpl

public static EntityManagerSetupImpl getEntityManagerSetupImpl(String emName)

Return the setup class for a given entity manager name

Parameters:

emName -

getEmSetupImpls

public static Map<String,EntityManagerSetupImpl> getEmSetupImpls()

mergeMaps

public static Map mergeMaps(Map target,
                            Map source)

Merge the properties from the source object into the target object. If the property exists in both objects, use the one from the target

Parameters:

target -

source -

Returns:

the target object

removeSpecifiedProperties

public static Map removeSpecifiedProperties(Map source,
                                            Collection keysToBeRemoved)

Copies source into target, removes from target all keysToBeRemoved.

Parameters:

source -

keysToBeRemoved -

Returns:

the target object

keepSpecifiedProperties

public static Map keepSpecifiedProperties(Map source,
                                          Collection keysToBeKept)

target contains the entries from source with keysToBeKept.

Parameters:

source -

keysToBeKept -

Returns:

the target object

splitSpecifiedProperties

public static Map[] splitSpecifiedProperties(Map source,
                                             Collection keysToBeKept)

target is a array of two Maps the first one contains specified properties; the second all the rest.

Parameters:

source -

keysToBeKept -

Returns:

the target object

splitProperties

public static Map[] splitProperties(Map source,
                                    Collection[] keys)

Source Map is divided between Map[] in target. Target's i-th member contains all source's Map.Entries keys for which are in keys[i] Collection. Target's size equals keys' size + 1: all the source's Map.Entries not found in any of keys Collections go into the last target's map.

Parameters:

source -

keys - is array of Maps of size n

Returns:

the target object is array of Maps of size n+1
