print.rawBlock

Print Method for Block of Binary Data

Description

This function displays a "rawBlock" 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 object contains parameters controlling the format of the display, some of which may be overridden in the call to print.

Usage

## S3 method for class 'rawBlock'
print(x, width = NULL, machine = NULL,
      sep1 = "  :  ", sep2 = "  |  ",
      showOffset = TRUE, showHuman = TRUE, 
      page = FALSE, ...)

Arguments

`x`	A `"rawBlock"` object.
`width`	The number of bytes to display per line of output.
`machine`	The machine format to display; either `"hex"` or `"binary"`.
`sep1`	A separator to insert between the block offset and the machine format.
`sep2`	A separator to insert between the machine format and the human-readable format.
`showOffset`	If `FALSE`, the column of offsets is not printed.
`showHuman`	If `FALSE`, the column of human-readable format is not printed.
`page`	If `TRUE` the output is sent to the file viewer specified by `getOption("pager")`.
`...`	Other arguments to `print`.

Details

If either width or machine is NULL, the relevant value is taken from the "rawBlock" object. The human-readable format is taken from the "rawBlock" object.
