HALAdaptor()
constructor for the HAL adaptor. |
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 |
cleanup()
this method is called whenever a reader is undefined. a basereader can override this method with its own cleanup routine. |
void |
connectReader()
sets up a reader. |
void |
disconnectReader()
destroys a reader. |
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 HALAdaptor. this method must be called befor the Adaptor can be used. |
void |
start()
starts a base reader to read tags. |
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. |
