class TxtRecord : public ResourceRecord { public: static constexpr uint16_t kType = kTypeTxt; void Init(uint16_t aClass = kClassInternet) { ResourceRecord::Init(kTypeTxt, aClass); } Error ReadTxtData(const Message &aMessage, uint16_t &aOffset, uint8_t *aTxtBuffer, uint16_t &aTxtBufferSize) const; static bool VerifyTxtData(const uint8_t *aTxtData, uint16_t aTxtLength, bool aAllowEmpty); };

Fields

Field

ot::Dns::TxtRecord::kType

Methods

Init()

Initializes the TXT Resource Record by setting its type and class. Other record fields (TTL, length) remain unchanged/uninitialized.

ReadTxtData() const

Parses and reads the TXT record data from a message. Also checks if the TXT data is well-formed by calling `VerifyTxtData()` when it is successfully read.

VerifyTxtData()

Tests if a buffer contains valid encoded TXT data.
