rfid.api.NXP

public class NXP
extends java.lang.Object

The NXP class comprises of the Access operations meant for NXP tags. These operation include SetEASWait and SetEASEvent(for setting/resetting EAS bits on NXP tags), ReadProtectWait & ResetReadProtectEvent(for setting the Quiet bit on one or more NXP tags), ResetReadProtectEvent(for resetting Quiet bit on all the NXP tags

void	readProtectEvent(NXP.ReadProtectParams readProtectParams, AccessFilter accessFilter, AntennaInfo antennaInfo) A set of NXP tags can be read-protected or put into Quiet mode by calling ReadProtectEvent method The method takes in the filter criteria for this set of tags while a null value for access-filter corresponds to entire tag population Addtionally, the antenna IDs on which the operation is to be performed can also be specified
void	readProtectWait(java.lang.String tagID, NXP.ReadProtectParams readProtectParams, AntennaInfo antennaInfo) An NXP tag can be protected from reading (i.e, Quiet mode) by calling the "ReadProtectWait" method.
void	resetReadProtectEvent(NXP.ResetReadProtectParams resetReadProtectParams, AntennaInfo antennaInfo) All the NXP tags with the same Access-Password can be put out of the Quiet-Mode.Hence,they will no longer be read-protected.

antennaInfo - set of antennae on which this access operation is to be performed

Throws:

InvalidUsageException

OperationFailureException

setEASEvent

public void setEASEvent(NXP.SetEASParams setEASParams,

readProtectWait

public void readProtectWait(java.lang.String tagID,
                            NXP.ReadProtectParams readProtectParams,

An NXP tag can be protected from reading (i.e, Quiet mode) by calling the "ReadProtectWait" method. It requires the Access-password for the NXP tag. The antenna-ID list on which the operation is to be performed is also AntennaInfo taken by the method.

Parameters:

tagID - NXP-tag's ID

readProtectParams - contains the Access-password for the tag

antennaInfo - Contains the list of antenna-IDs on which the operation is to be performed

Throws:

InvalidUsageException

OperationFailureException

readProtectEvent

public void readProtectEvent(NXP.ReadProtectParams readProtectParams,

                      throws InvalidUsageException,
                             OperationFailureException

A set of NXP tags can be read-protected or put into Quiet mode by calling ReadProtectEvent method The method takes in the filter criteria for this set of tags while a null value for access-filter corresponds to entire tag population Addtionally, the antenna IDs on which the operation is to be performed can also be specified

Parameters:

readProtectParams - consists of the Access password
