Detailed Description

This is a helper that represents TLV (tag, length, value) datatype.

A few specifications:

• The tag is one byte.
• The length is one byte.
• The value size is variable.

A TLV's value can be an other TLV. This scheme is supported.

)

Set the value.

value() [3/6]

void logicalaccess::TLV::value

Set the value.

value() [5/6]

void logicalaccess::TLV::value

(

tlv

)

Set an other TLV as the value of this TLV.

Parameters

tlv	the other TLV. Must not be NULL. Will not be copied.

value_u1()

uint8_t logicalaccess::TLV::value_u1

(

)

const

Return the "value" of this TLV as uint8_t. Throw if the value size is not exactly one byte.
