                    throws Throwable

Call service method according to settings specified in togglz.

Parameters:

facadeOperation - READ/WRITE operation, used by togglz flags

callInParallel - true means both oracle and lightblue will be called in parallel and state sharing between services will not be possible

returnedType - type of the returned object

methodName - method name to call

types - List of parameter types

values - List of parameters

Returns:

Object returned by dao

Throws:

Exception

Throwable

setLogResponseDataEnabled
