print.rawFormat: Print Method for Binary File Format

Description

This function displays a "rawFormat" object. Each line of output contains a binary offset, the binary data in a raw machine format, and an interpretation of the data in a human-readable format. The format consists of one or more sub-blocks and a heading line is added for each block. The object contains parameters controlling the format of the display, some of which may be overridden in the call to print.

Usage

# S3 method for rawFormat
print(x, sep1 = "  :  ", sep2 = "  |  ",
                  blockHead = TRUE, blockChar = "=", page = FALSE, ...)

Arguments

x

A "rawFormat" object.

sep1

A separator to insert between the format offset and the machine format.

sep2

A separator to insert between the machine format and the human-readable format.

blockHead

A logical indicating whether to print a header between blocks of the format.

blockChar

The character used as a prefix to the block names for printing headers between blocks.

page

If TRUE the output is sent to the file viewer specified by getOption("pager").

…

Other arguments to print.

Details

Information on the number of bytes on each line, the machine representation of each byte and the human-readable format are all taken from the taken from the "rawBlock" elements of the "rawFormat" object. Consequently each block can have a quite different appearance. Considerable effort is made to line up the separators across all blocks within the format.
