Instance Attribute Details

#flags ⇒ Integer

Returns 8-bit flags.

Returns:

  • (Integer) —

    8-bit flags



23
 
# File 'lib/packetgen/header/eap/tls.rb', line 23

define_field_before :body, :flags, Types::Int8

#l ⇒ Boolean

Say if length field is included. Defined on #flags field.

Returns:

  • (Boolean) 


34
 
# File 'lib/packetgen/header/eap/tls.rb', line 34

define_bit_fields_on :flags, :l, :m, :s, :reserved, 5

#m ⇒ Boolean

Say if there are more fragments. Defined on #flags field.

Returns:

  • (Boolean) 


34
 
# File 'lib/packetgen/header/eap/tls.rb', line 34

define_bit_fields_on :flags, :l, :m, :s, :reserved, 5

#s ⇒ Boolean

If set, this message is a TLS-Start. Defined on #flags field.

Returns:

  • (Boolean) 


34
 
# File 'lib/packetgen/header/eap/tls.rb', line 34

define_bit_fields_on :flags, :l, :m, :s, :reserved, 5

#tls_length ⇒ Integer

TLS message length. This field provides the total length of the TLS message or set of messages that is being fragmented. So, it cannot be automatically calculated (no #calc_length method).

Returns:

  • (Integer) —

    32-bit TLS length

# File 'lib/packetgen/header/eap/tls.rb', line 44

define_field_before :body, :tls_length, Types::Int32,
optional: ->(h) { h.l? }
