Class OsmSegmenter.WayFileSorter

java.lang.Object

org.ka2ddo.yaac.osm.OsmSegmenter.WayFileSorter

All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

OsmSegmenter

protected class OsmSegmenter.WayFileSorter
extends java.lang.Object
implements java.lang.Runnable

This class handles the logic of sorting a temporary .ways file into the proper order for correct rendering. Because it returns multiple data items, it had to be made into a method object.

Constructor Detail

WayFileSorter

public WayFileSorter(StatusListener listener,
                     byte[] buf,
                     int latDirArrayLength,
                     java.io.PrintStream out)

Create a reusable WayFileSorter instance.

Parameters:

listener - StatusListener to report progress of sorting

buf - byte array to use for buffered reading and writing of ways file

latDirArrayLength - the number of latitude directories to be searched through (for computing percentage progress)

out - PrintStream for OsmSegmenter log file

WayFileSorter

public WayFileSorter(StatusListener listener,
                     int bufSize,
                     FastBlockingQueue<java.io.File> fileSource,
                     java.io.PrintStream out)

Create a reusable WayFileSorter instance.

Parameters:

listener - StatusListener to report progress of sorting

bufSize - size of byte array to use for buffered reading and writing of ways file

fileSource - FastBlockingQueue that can provide a sequence of File objects to sort

out - PrintStream for OsmSegmenter log file

Method Detail

run

public void run()

DO NOT CALL. Reserved for parallel processing of Way file sorting after use of WayFileSorter(StatusListener, int, FastBlockingQueue<File>, PrintStream) constructor.

Specified by:

run in interface java.lang.Runnable

setNoMoreFiles

public void setNoMoreFiles(boolean noMoreFiles)

Indicate to parallel way sorter thread that there are no more way files to be put into the queue.

Parameters:

noMoreFiles - boolean true if we are out of unsorted way files

getNumSortFailures

public int getNumSortFailures()

Report the number of times the sort didn't succeed (usually due to file reading problems).

Returns:

number of sort failures (normally 0, may be 1)

getNumDupWaysDeleted

public int getNumDupWaysDeleted()

Report the number of Way records deleted from the file as being exact duplicates or subsets of other Ways.

Returns:

count of deleted Way records

sortFile

public void sortFile(java.io.File wayFile,
                     int latIdx)
              throws java.io.IOException

Sort a temporary ways file into the proper permanent order.

Parameters:

wayFile - File identifying the temporary file to sort

latIdx - int array index of the latitude (used to calculate progress bar percentage)

Throws:

java.io.IOException - if file could not be read or written

getFailureReason

public java.lang.Throwable getFailureReason()

Get reason why this sorter crashed.

Returns:

Throwable why this sorter crashed or null if no failure
