Member Function Documentation

◆ attachable()

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::DataSink, and Botan::SecureQueue.

Definition at line 53 of file filter.h.

53{ return true; }

◆ end_msg()

virtual void Botan::Filter::end_msg ( )
inlinevirtualinherited

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

Reimplemented in Botan::Base64_Decoder, Botan::Base64_Encoder, Botan::DataSink_Stream, Botan::Hex_Decoder, and Botan::Hex_Encoder.

Definition at line 46 of file filter.h.

46 { /* default empty */
47 }

◆ name()

std::string Botan::BitBucket::name ( ) const
inlineoverridevirtual
Returns
descriptive name for this filter

Implements Botan::Filter.
