as.character.rawFormat

Convert Binary File Format into Strings

Description

This function takes a "rawFormat" object and generates human-readable strings for displaying the format. Each string 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.

Usage

## S3 method for class 'rawFormat'
as.character(x, sep1 = "  :  ", sep2 = "  |  ",
                blockHead = TRUE, blockChar = "=", ...)

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.
`...`	Other arguments to `as.character`.

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.

Value

A character vector.
