Method Detail

getInstance

public static OSManager getInstance()

addLibraryPath

public void addLibraryPath(String pathToAdd)
                    throws Exception

Add the library path to the ohNet.so file. Not clever enough to work out how to override ClassLoader functionality, so using this nice trick instead..

Parameters:

pathToAdd -

Throws:

NoSuchFieldException

SecurityException

IllegalArgumentException

IllegalAccessException

Exception

setJavaPath

private void setJavaPath()

Set the Path to the ohNetxx.so files

constructLibraryPath

public String constructLibraryPath()

Constructs the additional library path. public to avoid problems for unit tests.

Returns:

getOhnetLibDir

public String getOhnetLibDir()

retrieves the path suffix for the ohNet.so files (suffix in this case means all path elements inclusive /mediaplayer_lib). E.g. you will receive mediaplayer_lib/ohNet/linux/amd64, if you are running on an amd64 system. The default is OHNET_LIB_DIR + "/default". If your system is not recognized, you are still able to copy your applicable libs to this directory and use the mediaplayer.

Returns:

getFilePath

public String getFilePath(Class mClass,
                 boolean bUseFullNamePath)

Get the Path of this ClassFile and/or the path of the current JAR, which should be basically the same! No? Returned to the old method because the new method did not work when a plugin requested the path. Getting LCD.xml from Directory: /C:/Keep/git/repository/MediaPlayer/com.upnp.mediaplayer/bin Instead of /C:/Keep/git/repository/MediaPlayer/com.upnp.mediaplayer/bin/org/rpi/plugin/lcddisplay/ For unit testing or for other special circumstances a system property "mediaplayer.core.home" variable is used. If this variable is set, the value of this variable is returned instead of the path of the current class.

Returns:

loadPlugins

public void loadPlugins()

Load the Plugins

listFiles

private List<File> listFiles(String directoryName)

List all the files in this directory and sub directories.

Parameters:

directoryName -

Returns:

isRaspi

public boolean isRaspi()

Is this a Raspberry Pi

Returns:

setRaspi

private void setRaspi(boolean bRaspi)

isSoftFloat

public boolean isSoftFloat()

Is this a SoftFloat Raspberry Pi

Returns:

dispose

public void dispose()

Tidy up..

getGpio

getBashVersionInfo

private static String getBashVersionInfo()

hasReadElfTag
