PlainTagConnectionPlainTagConnection — interface in package javax.microedition.contactless.rfpublic interface PlainTagConnection extends javax.microedition.contactless.TagConnectionMethod summaryjava.util.Vectortransceive(java.util.Vector input)InheritanceMethods inherited from class javax.microedition.io.ConnectioncloseAll superinterfacesDescriptionMethodsjavax.microedition.contactless.TagConnectionThis interface defines the basic mechanism to communicate with the different RFID tags that contain non-NFC Forumformatted data. This data is usually in the format defined by the tag vendor. Each of these data formats have their ownspecial features and access commands.This interface provides high level method to access non-NFC Forum formatted data on the target. The execution of, forexample, read command on a tag might require also the authentication and the data area selection before the actual readcan be done. From the application perspective it would be easiest to do all these actions with one method call. Thereforethis interface provides a Vector input parameter to set all the needed commands into one parameter and send them tothe target with one method call. Each command is presented as one element in the Vector . The returned Vectorcontains the elements that correspond to the return values of the commands in the input Vector . The Vector is usedto make the handling of separate commands and their return values easier.Still there may be a need to specify more tag-specific classes that support the actual structure and properties of the physicaltag. These more detailed tag-specific classes are out of scope for this API.transceive(java.util.Vector)ParametersReturnsThrowspublic java.util.Vector transceive(java.util.Vector input) throwsjavax.microedition.contactless.ContactlessException, java.io.IOExceptionThis method allows the applications to communicate with the discovered RFID tag. The tag specific access commands areset to the input vector. These commands can be for example an authentication command and after that a read commandwith needed sector and block information.Since operations performed on the tag vary based on the physical type of the tag, return value of this method is impossibleto define. Therefore an output vector is provided into the method and the results of the requested commands are placedinto it.input - commands requested to be performed on the tagthe result of the performed commandsContactlessException - if commands cannot be performed or the operation is not supported by the API implementation46
