Detailed Description

The Size Record contains a four-byte, 32-bit, unsigned integer, which contains the size of object that the URI field refers to.

Note that in practice this is limited to URLs (http://, ftp:// and similar). The Size Record's Local Type Name is "s".

The size is expressed in network byte order (most significant byte first). For example, if Byte 0 contains 0x12, Byte 1 contains 0x34, Byte 2 contains 0x56, and Byte 3 0x78, the size of the referred object is 0x12345678 bytes.

The size record MAY be used by the device to determine whether it can accommodate the referenced file or not. For example, an NFC tag could trigger the download of an application to a cell phone. Using a combination of the Type Record and the Size Record, the mobile phone could determine whether it can accommodate such a program or not.

The Size Record is for informational purposes only. Since the object size in the network may vary (for example, due to updates), this value should be used as a guideline only.

The Size Record is optional to support.

Constructor & Destructor Documentation

◆ NdefSpSizeRecord() [1/2]

NdefLibrary.Ndef.NdefSpSizeRecord.NdefSpSizeRecord ( )

Create an empty size record, to be used within a Smart Poster message. Automatically creates the payload and sets it to size 0.

◆ NdefSpSizeRecord() [2/2]

NdefLibrary.Ndef.NdefSpSizeRecord.NdefSpSizeRecord ( NdefRecord other )

Create a size record based on the record passed through the argument.

Internalizes and parses the payload of the original record. The original record has to be an action record as well.

Parameters

other Size record to copy into this record.

Member Function Documentation

◆ IsRecordType()

static bool NdefLibrary.Ndef.NdefSpSizeRecord.IsRecordType ( NdefRecord record )

static

Checks if the record sent via the parameter is indeed a size record.

Only checks the type and type name format, doesn't analyze if the payload is valid.

Parameters

record Record to check.

Returns: True if the record has the correct type and type name format to be a size record, false if it's a different record.

Property Documentation

◆ NfcSize

uint NdefLibrary.Ndef.NdefSpSizeRecord.NfcSize

getset

Size of the linked content.
