Detailed Description

The srecord::input_filter_message class is used to represent an abstract base class for filters that must operate on the complete data, in order, in order to functions (e.g.

CRC, message digest, etc).

All of the machinery for accumulating the input data and eventually forwarding it on are in this common base class. The only methods that a derived class must supply are data block processing and results creation.

Constructor & Destructor Documentation

◆ ~input_filter_message()

virtual srecord::input_filter_message::~input_filter_message ( )
virtual

The destructor.

◆ input_filter_message()

srecord::input_filter_message::input_filter_message ( const input::pointer & deeper,
bool naked = false )
protected

The constructor.

Parameters
deeperThe data to be filtered.
nakedWhether or not to forward the data: true means result only with no data, false means result and data.

Referenced by get_minimum_alignment().

Member Function Documentation

◆ read()

bool srecord::input_filter_message::read ( record & rec)
protectedvirtual

The read method is used to read one record from the input.

It returns 0 at the end of the input, and 1 if a record is read successfully.

See the srecord::record documentation (header file) for details of the various record types.

Note: there is no guarantee that a header record will appear first, or that a execution start address record will appear last.

Parameters
recWhere to put the returned data.
Returns
bool; true if data was read, false if at end-of-file

Reimplemented from srecord::input_filter.

◆ process()

virtual void srecord::input_filter_message::process ( const memory & input,
record & output )
protectedpure virtual

◆ get_algorithm_name()

◆ get_minimum_alignment()

virtual unsigned srecord::input_filter_message::get_minimum_alignment ( void ) const
protectedvirtual

The get_minimum_alignment method is used to obtain the minium require dbyte alignment.

Returns 0 if irrelevant.

Reimplemented in srecord::input_filter_message_stm32.
