dk.dma.ais.reader.AisReader

dk.dma.ais.reader.AisDirectoryReader

All Implemented Interfaces:

Runnable

public class AisDirectoryReader
extends AisReader

AIS reader that iterates over every file from a given base directory. If a file matches a given pattern it will be read.

If recursive used all sub directories will also be scanned using depth first.

Default ordering is by full path names. A Comparator<Path> can be provided for alternative ordering.

Method Detail

run

public void run()

Specified by:

run in interface Runnable

Overrides:

run in class Thread

getStatus

public AisReader.Status getStatus()

Description copied from class: AisReader

Get the status of the connection, either connected or disconnected

Specified by:

getStatus in class AisReader

Returns:

status status

send

public void send(SendRequest sendRequest,
                 Consumer<Abk> resultListener)
          throws SendException

Description copied from class: AisReader

Method to send addressed or broadcast AIS messages (ABM or BBM).

Specified by:

send in class AisReader

Parameters:

sendRequest - the send request

resultListener - A class to handle the result when it is ready.

Throws:

SendException - the send exception

getEstimatedFractionOfPacketsRead

public float getEstimatedFractionOfPacketsRead()

Compute an estimate of the fraction of AIS packets which have been read, out of the total no. of AIS packets to read in the matching files. The first call to this method may be long-running as it will scan all the matching files to count AIS packets.

Returns:

Estimated fraction of AIS packets read as a floating point number between 0 and 1.
