-Interface org.neard.Target
-Object path [variable prefix]/{nfc0}/{target0, target1...}
-
-Method dict GetProperties()
-
- Returns all properties for the device. See the
- properties section for available properties.
-
- Possible Errors: org.neard.Error.DoesNotExist
-
- void SetProperty(string name, variant value)
-
- Changes the value of the specified property. Only
- properties that are listed a read-write are changeable.
- On success this will emit a PropertyChanged signal.
-
- Possible Errors: org.neard.Error.DoesNotExist
- org.neard.Error.InvalidArguments
-
-
-Signals PropertyChanged(string name, variant value)
-
- This signal indicates a changed value of the given
- property.
-
-
-Properties string Type [readonly]
-
- The NFC target type.
-
- Valid types are "tag" and "device".
-
- array{string} Protocols [readonly]
-
- The target supported protocols.
- Possible values are "Felica", "MIFARE", "Jewel",
- "ISO-DEP" and "NFC-DEP".
-
- array{string} TagType [readonly]
-
- The tag type.
- Possible values are "Type 1", "Type 2", "Type 3",
- "Type 4" and "NFC-DEP"
- This is only valid for tag type targets.
-
- array{object} Records [readonly]
-
- List of NDEF records object paths.
- This is only valid for tag type targets.
-
- boolean ReadOnly [readonly]
-
- Give the current status of tag's read mode
- This is valid for tag type and device targets

-
-Record hierarchy
-================
-
-Service org.neard
-Interface org.neard.Record
-Object path [variable prefix]/{nfc0}/{target0}/{record0,record1,...}
-
-Method dict GetProperties()
-
- Returns all properties for the record. Each record
- has it's type and properties.
-
- If type has "Text", possible properties are "Encoding",
- "Language" and "Representation".
-
- See the properties section for available properties.
-
- Possible Errors: org.neard.Error.DoesNotExist
-
-Properties string Type [readonly]
-
- The NDEF record type name.
-
- Possible values are "SmartPoster", "Text", "URI",
- "HandoverRequest", "HandoverSelect", "HandoverCarrier".
-
- string Encoding [readonly]
-
- The character encoding.
-
- Possible values are "UTF-8" or "UTF-16".
- This property is only valid for Text and SmartPoster's
- title records.
-
- string Language [readonly]
-
- The ISO/IANA language code (For example "en" or "jp").
-
- This property is only valid for Text and SmartPoster's
- title records.
-
- string Representation [readonly]
-
- The human readable representation of a text or
- title record.
-
- This property is only valid for Text and SmartPoster's
- title records.
-
- string URI [readonly]
-
- The record URI (for example https://nfc-forum.org).
-
- This is the complete URI, including the scheme and
- the resource.
- This property is only valid for SmartPoster's URI records.
-
- string MIMEType [readonly]
-
- The URI object MIME type.
-
- This is a description of the MIME type of the object
- the URI points at.
- This is not a mandatory field and is only valid for
- Smart Posters carrying a URI record.
-
- uint32 Size [readonly]
-
- The URI object size.
-
- This is the size of the object the URI points at.
- It should be used by applications to decide if they can
- afford to fetch the object or not.
- This is not a mandatory field and is only valid for
- Smart Posters carrying a URI record.
-
- string Action [readonly]
-
- The suggested course of action.
-
- This one is only valid for Smart Posters and is a
- suggestion only. It can be ignored, and the possible
- values are "Do" (for example launch the browser),
- "Save" (for example save the URI in the bookmarks folder,
- or "Edit" (for example open the URI in an URI editor for
- the user to modify it.
