The Alternative Carrier record is used within the payload of the Handover Select record to describe a single alternative carrier.
This record essentially describes a single alternative carrier, including its power state and a reference to where further details can be found - this is done by referencing the ID of the other NDEF record within the same handover message. The pointed record may be a Handover Carrier record or a Carrier Configuration record.
Optional Auxiliary Data reference(s) are pointers to NDEF records that contain additional information about the alternative carrier. There are no limitations on the type of record that can be pointed to.
|
strong |
Enum to conveniently access the 2-bit field that indicates the carrier power state.
| NdefLibrary.Ndef.NdefHandoverAlternativeCarrierRecord.NdefHandoverAlternativeCarrierRecord | ( | ) |
Create an empty Alternative Carrier Record.
| NdefLibrary.Ndef.NdefHandoverAlternativeCarrierRecord.NdefHandoverAlternativeCarrierRecord | ( | NdefRecord | other | ) |
Create an Alternative Carrier 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 Alternative Carrier Record as well.
| other | Record to copy into this Alternative Carrier Record. |
| NdefException | Thrown if attempting to create a Alternative Carrier Record based on an incompatible record type. |
| void NdefLibrary.Ndef.NdefHandoverAlternativeCarrierRecord.AddAuxiliaryDataReference | ( | byte [] | auxiliaryDataReference | ) |
Convenience method to add another auxiliary data reference to the list. Using this method ensures that the list is already created and updates the payload according to the changes.
If you manually modify the AuxiliaryDataReferenceList, you need to call AssemblePayload() manually when you are finished with changes and want the payload to be synchronized to the properties.
| auxiliaryDataReference | The auxiliary data reference to add. This is the record ID of another record within the Handover Select payload which contains additional information about this alternative carrier. |
| bool NdefLibrary.Ndef.NdefHandoverAlternativeCarrierRecord.AssemblePayload | ( | ) |
Create the payload based on the data stored in the properties. Usually called automatically when changing properties, but you might need to call this manually if you modify the list of auxiliary data references directly without using accessor method provided by this class.
| NdefException | Thrown if unable to assemble the payload. The exception message contains further details about the issue. |
|
virtual |
Checks if the contents of the record are valid; throws an exception if a problem is found, containing a textual description of the issue.
| NdefException | Thrown if no valid NDEF record can be created based on the record's current contents. The exception message contains further details about the issue. |
Reimplemented from NdefLibrary.Ndef.NdefRecord.
|

Checks if the record sent via the parameter is indeed a Handover Alternate Carrier record. Checks the type and type name format.
| record | Record to check. |

Type of the Alternative Carrier Record.
|
getset |
An Auxiliary Data Reference is a pointer to an NDEF record that gives additional information about the alternative carrier.
|
getset |
The Carrier Data Reference is a pointer to an NDEF record that uniquely identifies the carrier technology.
Reference is the record ID of a Handover Carrier record or a Carrier Configuration Record (can also be a Bluetooth Secure Simple Pairing record)
|
getset |
Access the byte array that should contain chars forming a number as a string for easier manipulation from within an app.
|
getset |
2-bit field that indicates the carrier power state.
|
getset |
Access the Carrier Power State property as a byte instead of the enum. Note that according to the current Bluetooth specification (1.3), only two bits of the byte are in use for the Carrier Power State.
If setting a Carrier power state that is not known by the enum, the internal value is set to Unknown.
