Method Summary

void	addTag(Tag tag) whenever a new Tag is read a notification is sent to the observers.
void	addTags(java.util.List<Tag> tags) whenever new Tags are read a notification is sent to the observers.
void	connectReader() sets up a reader. if the adaptor can be connected to the rp-proxy the adaptor will be set to connected.
void	disconnectReader() destroys a reader.
java.lang.String	getCommandChannelHost() returns the commandChannelHost of the rp-proxy.
int	getCommandChannelPort() returns the commandChannelPort of the rp-proxy.
java.lang.String	getNotificationChannelHost() returns the notificationChannelHost of the rp-proxy.
int	getNotificationChannelPort() returns the notificationChannelPort of the rp-proxy.
int	getReadTimeInterval() returns the readTimeInterval.
java.util.Set<java.lang.String>	getSources() returns the sources from where the reader reads tags.
org.fosstrak.hal.Observation[]	identify(java.lang.String[] readPointNames) Triggers the identification of all tags that are currently available on the reader. this method is used when the IdentifyThread is used to poll the adaptor.
void	initialize(java.lang.String name, org.fosstrak.ale.xsd.ale.epcglobal.LRSpec spec) initializes a RPAdaptor. this method must be called befor the Adaptor can be used.
void	start() starts a base reader to read tags. if the reader is not yet connected this command will connect the reader immediately and then start it.
void	stop() stops a reader from reading tags.
void	update(org.fosstrak.ale.xsd.ale.epcglobal.LRSpec spec) updates a reader according the specified LRSpec.

Method Detail

initialize

public void initialize(java.lang.String name,
                       org.fosstrak.ale.xsd.ale.epcglobal.LRSpec spec)
                throws org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

initializes a RPAdaptor. this method must be called befor the Adaptor can be used.

Overrides:

initialize in class BaseReader

Parameters:

name - the name for the reader encapsulated by this adaptor.

spec - the specification that describes the current reader.

Throws:

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationException - whenever an internal error occurs.

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

connectReader

public void connectReader()
                   throws org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

sets up a reader. if the adaptor can be connected to the rp-proxy the adaptor will be set to connected.

Specified by:

connectReader in class BaseReader

Throws:

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationException - whenever an internal error occured

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

disconnectReader

public void disconnectReader()
                      throws org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

destroys a reader.

Specified by:

disconnectReader in class BaseReader

Throws:

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationException - whenever an internal error occured

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

addTag

public void addTag(Tag tag)

whenever a new Tag is read a notification is sent to the observers.

Specified by:

addTag in class BaseReader

Parameters:

tag - a tag read on the reader

addTags

public void addTags(java.util.List<Tag> tags)

whenever new Tags are read a notification is sent to the observers.

Specified by:

addTags in class BaseReader

Parameters:

tags - a list of tags to be added to the reader

start

public void start()

starts a base reader to read tags. if the reader is not yet connected this command will connect the reader immediately and then start it. If the reader cannot be connected then the reader is not started as well.

Specified by:

start in class BaseReader

stop

public void stop()

stops a reader from reading tags.

Specified by:

stop in class BaseReader

update

public void update(org.fosstrak.ale.xsd.ale.epcglobal.LRSpec spec)
            throws org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

updates a reader according the specified LRSpec.

Specified by:

update in class BaseReader

Parameters:

spec - LRSpec for the reader

Throws:

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationException - whenever an internal error occurs

org.fosstrak.ale.wsdl.ale.epcglobal.ImplementationExceptionResponse

identify

public org.fosstrak.hal.Observation[] identify(java.lang.String[] readPointNames)
                                        throws org.fosstrak.hal.HardwareException

Triggers the identification of all tags that are currently available on the reader. this method is used when the IdentifyThread is used to poll the adaptor.

Specified by:

identify in class BaseReader
