Constructor Detail

ReaderConnection

public ReaderConnection(RdrMetadata rdr,
                        int[] antIDs,
                        java.lang.String keyStorePath,
                        char[] keyStorePw,
                        long hashSalt)

Creates a new ReaderConnection with the specified parameters.

Parameters:

rdr - Metadata for the reader to connect to

antIDs - The IDs of the reader's antennas in ascending order

keyStorePath - Absolute path to the keystore to use for SSL

keyStorePw - The password for the keystore

hashSalt - The initial salt for the hash function

Method Detail

addListener

public void addListener(ReaderConnectionListener l)

Adds a ReaderConnectionListener to the list of listeners.

Parameters:

l - The ReaderConnectionListener to add

stopConnection

public void stopConnection()

Stops this ReaderConnection from reading.

run

public void run()

The run method from class Thread. Repeatedly tries to connect to the reader via a socket connection. Once the connection handshake succeeds, it repeatedly reads incoming TREs from the reader, parses them, and offers them to the ReaderGateway.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

toString

public java.lang.String toString()

Returns a String representing this ReaderConnection.

Overrides:

toString in class java.lang.Thread

Returns:

A String representing this ReaderConnection
