Returns true if vi mode is active. Returns false if not.
Raises NotImplementedError if the using readline library does not support.
Specifies Emacs editing mode. The default is this mode. See the manual of GNU Readline for details of Emacs editing mode.
Raises NotImplementedError if the using readline library does not support.
Returns true if emacs mode is active. Returns false if not.
Raises NotImplementedError if the using readline library does not support.
Should be implemented by a extended class.
tsort_each_child is used to iterate for child nodes of node.
Return the length of the hash value in bytes.
Return the length of the hash value (the digest) in bytes.
Digest::SHA256.new.digest_length * 8 # => 256 Digest::SHA384.new.digest_length * 8 # => 384 Digest::SHA512.new.digest_length * 8 # => 512
For example, digests produced by Digest::SHA256 will always be 32 bytes (256 bits) in size.
Disable a call to dlclose() when this handle is garbage collected.
Returns the output size of the digest, i.e. the length in bytes of the final message digest result.
digest = OpenSSL::Digest.new('SHA1') puts digest.digest_length # => 20
Replace %w+% into the environment value of what is contained between the %‘s This method is used for REG_EXPAND_SZ.

Sets the preset dictionary and returns string. This method is available just only after Zlib::Deflate.new or Zlib::ZStream#reset method was called. See zlib.h for details.
Can raise errors of Z_STREAM_ERROR if a parameter is invalid (such as NULL dictionary) or the stream state is inconsistent, Z_DATA_ERROR if the given dictionary doesn’t match the expected one (incorrect adler32 value)
Provide the inflate stream with a dictionary that may be required in the future. Multiple dictionaries may be provided. The inflate stream will automatically choose the correct user-provided dictionary based on the stream’s required dictionary.
Sets the preset dictionary and returns string. This method is available just only after a Zlib::NeedDict exception was raised. See zlib.h for details.
See Zlib::GzipReader documentation for a description.
See Zlib::GzipReader documentation for a description.
Returns the number of the first source line where the instruction sequence was loaded from.
For example, using irb:
iseq = RubyVM::InstructionSequence.compile('num = 1 + 2') #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> iseq.first_lineno #=> 1
Iterate all direct child instruction sequences. Iteration order is implementation/version defined so that people should not rely on the order.
Disable SSL for all new instances.
Disable SSL for all new instances.
Disables SMTP/TLS for this object. Must be called before the connection is established to have any effect.
Disables SMTP/TLS (STARTTLS) for this object. Must be called before the connection is established to have any effect.
Returns an expiry Time based on sec which can be one of:
