See IO#readchar.

Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.

Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.

See IO#readpartial for full details.

Reads a one-character string from the stream. Raises an EOFError at end of file.

If a block is given, it prints out each of the elements encountered. Block parameters are (in that order):

• depth: The recursion depth, plus one with each constructed value being encountered (Number)

• offset: Current byte offset (Number)

• header length: Combined length in bytes of the Tag and Length headers. (Number)

• length: The overall remaining length of the entire data (Number)

• constructed: Whether this value is constructed or not (Boolean)

• tag_class: Current tag class (Symbol)

• tag: The current tag (Number)

Example

der = File.binread('asn1data.der')
OpenSSL::ASN1.traverse(der) do | depth, offset, header_len, length, constructed, tag_class, tag|
  puts "Depth: #{depth} Offset: #{offset} Length: #{length}"
  puts "Header length: #{header_len} Tag: #{tag} Tag class: #{tag_class} Constructed: #{constructed}"
end

Clears the GC profiler data.

Returns whether the form contained multipart/form-data

Generate a TextArea element, as a String.

name is the name of the textarea. cols is the number of columns and rows is the number of rows in the display.

Alternatively, the attributes can be specified as a hash.

The body is provided by the passed-in no-argument block

textarea("name")
   # = textarea("NAME" => "name", "COLS" => 70, "ROWS" => 10)

textarea("name", 40, 5)
   # = textarea("NAME" => "name", "COLS" => 40, "ROWS" => 5)

Returns an Array of Range objects which represent the Range: HTTP header field, or nil if there is no such header.

returns a charset parameter in Content-Type field. It is downcased for canonicalization.

If charset parameter is not given but a block is given, the block is called and its result is returned. It can be used to guess charset.

If charset parameter and block is not given, nil is returned except text type in HTTP. In that case, “iso-8859-1” is returned as defined by RFC2616 3.7.1.

Parses self destructively and returns self containing the rest arguments left unparsed.

Displays the given statement on the standard output (or equivalent).

Load extra data embed into binary format String object.

Returns an array of instance variable names for the receiver. Note that simply defining an accessor does not create the corresponding instance variable.

class Fred
  attr_accessor :a1
  def initialize
    @iv = 3
  end
end
Fred.new.instance_variables   #=> [:@iv]
