Method Detail

performSequence

public void performSequence()
                     throws InvalidUsageException,
                            OperationFailureException

This method starts the execution of all operations in the Tag Access Sequence in the order in which the operations were added. The operation will be performed on all Antennas and will start execution immediately after the call, and will stop when StopSequence() is invoked.

Throws:

InvalidUsageException

OperationFailureException

performSequence

public void performSequence(AccessFilter accessFilterInfo,
                            TriggerInfo triggerInfo,
                            AntennaInfo antennaInfo)
                     throws InvalidUsageException,
                            OperationFailureException

This method starts the execution of all operations in the Tag Access Sequence in the order in which the operations were added. The operation will be performed on Antennas mentioned in antennaInfo and will start and stop execution based on triggerInfo. It can also be stopped by calling StopSequence().

Parameters:

accessFilterInfo - Access Filter which determines the Tags on which the Access operation sequence is to be performed. If this is null, operation will be perfomed without any access filters.

triggerInfo - Start/Stop criteria for current operation. If null, no trigger criteria will be used, which means the operation starts immediatly and stops when StopSequence() is invoked.

antennaInfo - Antennas on which the current operation is to be performed. If this is null, operation will be performed on all Antennas.

Throws:

InvalidUsageException

OperationFailureException

stopSequence

public void stopSequence()
                  throws InvalidUsageException,
                         OperationFailureException

This method stops the execution of the Tag Access Operation Sequence.

Throws:

InvalidUsageException

OperationFailureException

getLength

public int getLength()

Get the Operation Sequence Length

getOperation

public java.lang.Object getOperation(int index)
                              throws InvalidUsageException

Returns the operation already added at specified index.

Parameters:

index -

Returns:

Returns the operation already added at specified index.

Throws:

InvalidUsageException

add

public void add(TagAccess.Sequence.Operation operation)
         throws InvalidUsageException,
                OperationFailureException

Adds an operation to the Tag Access Sequence. Application should allocate new object for Operation for each call to Add().

Parameters:

operation -

Throws:

InvalidUsageException

OperationFailureException

delete

public void delete(TagAccess.Sequence.Operation operation)
            throws InvalidUsageException,
                   OperationFailureException

Removes an already added operation from the Tag Access Sequence.

Parameters:

operation -

Throws:

InvalidUsageException

OperationFailureException

deleteAll

public void deleteAll()
               throws InvalidUsageException,
                      OperationFailureException

Removes all added operations from the Tag Access Sequence.

Throws:

InvalidUsageException

OperationFailureException
