Member Function Documentation

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

Initialize or reinitialize this object, without signal propagation.

Parameters
parametersa 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 constuctors 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 InformationRecovery, and SecretRecovery.

size_t RawIDA::ChannelPut2 ( const std::string &  channel,
const byte *  inString,
size_t  length,
int  messageEnd,
bool  blocking 
)
inlinevirtual

Input multiple bytes for processing on a channel.

Parameters
channelthe channel to process the data.
inStringthe byte buffer to process.
lengththe size of the string, in bytes.
messageEndmeans how many filters to signal MessageEnd() to, including this one.
blockingspecifies whether the object should block when processing input.
Returns
the number of bytes that remain in the block (i.e., bytes not processed)

Implements Multichannel< Filter >.
