class NDEFRecordType¶

Public Types

enum TypeID¶

Type Name Format Field types

Represents 3-bit value describing record type, sets expectation for structure/content of record

Values:

Empty = 0x00¶

Record does not contain any information.

WellKnown = 0x01¶

Well Known Data Type - Data is defined by Record Type Definition (RTD) specification from NFC Forum.

MIMEMedia = 0x02¶

MIME Media - Data is one of the data types normally found in internet communications defined in RFC 2046.

AbsoluteURI = 0x03¶

Absolute Uniform Resource Identifier - Pointer to a resource following the RFC 3986 syntax.

External = 0x04¶

User-defined data that relies on the format specified by the RTD specification.

Unknown = 0x05¶

Unknown data type - Type length must be set to 0

Unchanged = 0x06¶

Indicates this payload is a part of a chunked record, with the type unchanged from the first chunk.

Invalid = 0x07¶

Invalid value, used for from_byte() helper. Value 0x07 is reserved by the NFC Forum.

Public Static Functions

NDEFRecordType from_bytes(std::vector<uint8_t> bytes, size_t offset = 0)¶

Creates an NDEFRecordType object from a vector of bytes starting at offset.

Return

type value matching value, ::TypeID::Invalid if value does not match any TypeID Name Format field

Parameters

• bytes: vector of octets (bytes) of data to create RecordHeader object from

• offset: offset within values vector to start from

static NDEFRecordType from_bytes(uint8_t bytes[], size_t len, size_t offset = 0)¶

Return

type value matching value, #TypeID::Invalid if value does not match any TypeID Name Format field

Parameters

• bytes: array of octets (bytes) of data to create RecordHeader object from

• len: number of values in data array

• offset: offset within values vector to start from
