Get an array of all Instruction children. IMMUTABLE
for IO.copy_stream. Note: we may return a larger string than size here; but IO.copy_stream does not care.
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.
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 (Integer)
offset: Current byte offset (Integer)
header length: Combined length in bytes of the Tag and Length headers. (Integer)
length: The overall remaining length of the entire data (Integer)
constructed: Whether this value is constructed or not (Boolean)
tag_class: Current tag class (Symbol)
tag: The current tag number (Integer)
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
Returns whether the form contained multipart/form-data
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 that case, “utf-8” is returned as defined by RFC6838 4.2.1
<!NOTATION …>
Called when an instruction is encountered. EG: <?xsl sheet=‘foo’?> @p name the instruction name; in the example, “xsl” @p instruction the rest of the instruction. In the example, “sheet=‘foo’”
