def dehex(str)
  hexen = str.scan(/\x5cx[0-9a-fA-F]{2}/n)
  hexen.each { |h|
    str.gsub!(h,h[2,2].to_i(16).chr)
  }
  return str
end

#emit(sym, data) {|sym, data| ... } ⇒ Object

A way to sneak the yield back into the db importer. Used by the SAX parsers.

Yields:

  • (sym, data)

# File 'lib/msf/core/db_manager/import.rb', line 81

def emit(sym,data,&block)
  yield(sym,data)
end

#import(args = {}) {|:filetype, @import_filedata[:type]| ... } ⇒ Object

A dispatcher method that figures out the data's file type, and sends it off to the appropriate importer. Note that import_file_detect will raise an error if the filetype is unknown.

Yields:

  • (:filetype, @import_filedata[:type])

#import_file(args = {}, &block) ⇒ Object

Generic importer that automatically determines the file type being imported. Since this looks for vendor-specific strings in the given file, there shouldn't be any false detections, but no guarantees.
