Detailed Description

The srecord::input_filter class is an abstract interface for all of the various filters that can be applied to an incoming EPROM file.

Each filter is-a input, but each also has-a deeper input, from which is obtained the data to be filtered.

Definition at line 35 of file filter.h.

Constructor & Destructor Documentation

◆ ~input_filter()

virtual srecord::input_filter::~input_filter ( )
virtual

The destructor.

◆ input_filter()

srecord::input_filter::input_filter ( input::pointer deeper)
protected

The constructor.

Only derived classes may call.

Parameters
deeperThe deeper input to be filtered.

Member Function Documentation

◆ read()

bool srecord::input_filter::read ( class record & rec)
virtual

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

Implements srecord::input.

Reimplemented in srecord::input_filter_and, srecord::input_filter_bitrev, srecord::input_filter_byte_swap, srecord::input_filter_checksum, srecord::input_filter_crop, srecord::input_filter_fill, srecord::input_filter_interval, srecord::input_filter_message, srecord::input_filter_not, srecord::input_filter_offset, srecord::input_filter_or, srecord::input_filter_random_fill, srecord::input_filter_sequence, srecord::input_filter_split, srecord::input_filter_unfill, srecord::input_filter_unsplit, and srecord::input_filter_xor.

◆ filename()

std::string srecord::input_filter::filename ( ) const
virtual

The filename method is used to get the name of the input file being processed.

Derived classes must supply this method.

Implements srecord::input.

◆ filename_and_line()

std::string srecord::input_filter::filename_and_line ( ) const
virtual

The filename_and_line method is used to get the name and current line number within the file.

The default implementation simply calls the filename method and returns that. Text formats should be cleverer.

Reimplemented from srecord::input.

◆ get_file_format_name()

const char * srecord::input_filter::get_file_format_name ( ) const
virtual

The get_file_format_name method is used to find out the name of the file format being read.

Derived classes must supply this method.

Implements srecord::input.

◆ disable_checksum_validation()

void srecord::input_filter::disable_checksum_validation ( )
virtual

The disable_checksum_validation method is used to have this input stream ignore checksum errors.

Implements srecord::input.
