Detailed Description

This class represents pipe objects. A set of filters can be placed into a pipe, and information flows through the pipe until it reaches the end, where the output is collected for retrieval. If you're familiar with the Unix shell environment, this design will sound quite familiar.

Warning: This Pipe interface, and all associated types (Filter, etc) are considered decrepit, no longer used within the library itself, and likely will see no future development. Avoid in new code.

Member Function Documentation

◆ append()

void Botan::Pipe::append ( Filter * filt )

Insert a new filter at the back of the pipe Deprecated because runtime modification of Pipes is deprecated. You can instead use append_filter which only works before the first message is processed.

Parameters

filt	the new filter to insert

Definition at line 207 of file pipe.cpp.

                                {
   do_append(filter);
}

◆ append_filter()

void Botan::Pipe::append_filter ( Filter * filt )

Append a new filter onto the filter sequence. This may only be called immediately after initial construction, before any calls to start_msg have been made.

This function (unlike append) is not deprecated, as it allows only modification of the pipe at initialization (before use) rather than after messages have been processed.

Definition at line 211 of file pipe.cpp.

                                       {
   if(m_outputs->message_count() != 0) {
      throw Invalid_State("Cannot call Pipe::append_filter after start_msg");
   }
 
   do_append(filter);
