Class AbstractPhysicalDevice.TagProcessor

java.lang.Object
  com.connecterra.ale.reader.AbstractPhysicalDevice.TagProcessor

Direct Known Subclasses:

AbstractPhysicalDevice.TagData

Enclosing class:

AbstractPhysicalDevice

public abstract static class AbstractPhysicalDevice.TagProcessor
extends Object

The base class of objects which can be passed to AbstractPhysicalDevice.processOpSpecs(com.connecterra.ale.reader.AbstractPhysicalDevice.TagProcessor, java.util.List). Each TagProcessor represents a minimally-addressible object visible to the device. In RFID applications this is an RFID tag. AbstractPhysicalDevice.processOpSpecs(com.connecterra.ale.reader.AbstractPhysicalDevice.TagProcessor, java.util.List) takes in the list of requests from outside and attempts to delegate each request to the TagProcessor, by examining the TagProcessor to see which interfaces it implements. The interesting TagProcessor interfaces driver developers may wish to implement are:

AbstractPhysicalDevice.EPCglobalTagReadProcessor

AbstractPhysicalDevice.EPCglobalTagWriteProcessor

AbstractPhysicalDevice.EPCglobalTagProcessor

(a combination of the associated read and write processor interfaces)

AbstractPhysicalDevice.BankReadTagProcessor

AbstractPhysicalDevice.BankWriteTagProcessor

AbstractPhysicalDevice.BankTagProcessor

(a combination of the associated read and write processor interfaces)

AbstractPhysicalDevice.EPCglobalClass1Gen2TagProcessor

AbstractPhysicalDevice.AFIReadingTagProcessor

See the associated interfaces' Javadoc for more detail.

Constructor Detail

AbstractPhysicalDevice.TagProcessor

public AbstractPhysicalDevice.TagProcessor()

Method Detail

setDeviceTagReport

public void setDeviceTagReport(DeviceTagReport report)

Set the DeviceTagReport on the TagProcessor

Parameters:

report - the DeviceTagReport to associate with this tag

getDeviceTagReport

public DeviceTagReport getDeviceTagReport()

Returns:

the DeviceTagReport value associated with this tag

getParameters

protected Map getParameters()

Returns the set of parameters associated with the request being processed. These parameters may come from the ALE or ALEPC poll or immediate commands or the PCSpec parameter list.

Returns:

a Map of request parameters (parameter name → parameter value)

start

protected abstract void start()

This method is invoked first, before any of the TagProcessor methods.

finish

protected void finish()

This method is called last, after all TagProcessor methods have been invoked. If an implementor overrides this, it should call super.finish() in the course of its own finish() processing.
