Overview

The length octets of a BER element: short form, long form, or the indefinite marker. The decoded byte count is exposed as #length.

Defined in:

Constant Summary

AFTER_DESERIALIZE = [] of Nil

The length octets of a BER element: short form, long form, or the indefinite marker. The decoded byte count is exposed as #length.

BEFORE_SERIALIZE = [] of Nil

The length octets of a BER element: short form, long form, or the indefinite marker. The decoded byte count is exposed as #length.

ENDIAN = ["big"]

The length octets of a BER element: short form, long form, or the indefinite marker. The decoded byte count is exposed as #length.

KLASS_NAME = [ASN1::BER::Length]

The length octets of a BER element: short form, long form, or the indefinite marker. The decoded byte count is exposed as #length.

Class Method Summary

• .bit_fields

  The length octets of a BER element: short form, long form, or the indefinite marker.

Instance Method Summary

• #__format__ : IO::ByteFormat

  A group or bit_field captures the endianness at its declaration point, so declaring endian after one would silently leave it system-endian.

• #indefinite?
• #length : Int32

  We can pretty much safely assume no protocol is implementing more than positive Int32 length datagrams

• #length=(length : Int32)

  We can pretty much safely assume no protocol is implementing more than positive Int32 length datagrams

• #length_indicator : UInt8
• #length_indicator=(length_indicator : UInt8)
• #long : Bool
• #long=(long : UInt8)
• #long=(value : Bool)
• #long_bytes : Array(UInt8)
• #long_bytes=(long_bytes : Array(UInt8))
• #read(io : IO) : IO

  Reads the fields of this instance from io, in declaration order, and returns io.

• #write(io : IO)

  Writes the fields of this instance to io in declaration order.
