virtual bool Botan::Filter::attachable ( )
inlinevirtualinherited

Check whether this filter is an attachable filter.

Returns
true if this filter is attachable, false otherwise

Reimplemented in Botan::SecureQueue, and Botan::DataSink.

50 { return true; }
void Botan::PK_Verifier_Filter::end_msg ( )
virtual

Notify that the current message is finished; flush buffers and do end-of-message processing (if any).

Reimplemented from Botan::Filter.
