◆ IsolatedInitialize()

void RawIDA::IsolatedInitialize ( const NameValuePairs & parameters = g_nullNameValuePairs )

virtual

Initialize or reinitialize this object, without signal propagation.

Parameters

parameters a set of NameValuePairs to initialize this object

Exceptions

NotImplemented

IsolatedInitialize() is used to initialize or reinitialize an object using a variable number of arbitrarily typed arguments. The function avoids the need for multiple constructors providing all possible combintations of configurable parameters.

IsolatedInitialize() does not call Initialize() on attached transformations. If initialization should be propagated, then use the Initialize() function.

If a derived class does not override IsolatedInitialize(), then the base class throws NotImplemented.

Reimplemented from BufferedTransformation.

Reimplemented in SecretRecovery, and InformationRecovery.
