Constructor Details

ListLoader

public ListLoader()
           throws IOException

Creates a list loader that reads the startup sequence from the current class loader, i.e., from EASY_STARTUP_FILE_NAME.

Throws:

IOException - in case of loading the startup sequence fails

ListLoader

public ListLoader(ClassLoader loader)
           throws IOException

Creates a list loader that reads the startup sequence from the given class loader, i.e., from EASY_STARTUP_FILE_NAME.

Parameters:

loader - the class loader to load from

Throws:

IOException - in case of loading the startup sequence fails

ListLoader

public ListLoader(File listFile)
           throws IOException

Creates a list loader that reads the startup sequence from the given file.

Parameters:

listFile - the file to consider (may be null for reading information from the defailt classloader resource)

Throws:

IOException - in case of loading the startup sequence fails

ListLoader

public ListLoader(File listFile,
 ClassLoader loader)
           throws IOException

Creates a list loader that reads the startup sequence from the given file.

Parameters:

listFile - the file to consider (may be null for reading information from loader)

loader - the class loader to load from

Throws:

IOException - in case of loading the startup sequence fails

ListLoader

public ListLoader(InputStream is)
           throws IOException

Creates a list loader that reads the startup sequence from an input stream. is will be closed by this constructor.

Parameters:

is - the input stream containing the startup sequence

Throws:

IOException - in case of loading the startup sequence fails

ListLoader

public ListLoader(Reader reader)
           throws IOException

Creates a list loader that reads the startup sequence from a reader. reader will be closed by this constructor.

Parameters:

reader - the reader providing access to the startup sequence

Throws:

IOException - in case of loading the startup sequence fails

Method Details

load

private static List<StartupInfo> load(InputStream is)
                               throws IOException

Loads the startup sequence from an input stream. is will not be closed by this method.

Parameters:

is - the input stream containing the startup sequence

Returns:

the loaded startup information

Throws:

IOException - in case of loading the startup sequence fails

getStream

private static InputStream getStream(File listFile,
 ClassLoader loader)
                              throws IOException

Returns the underlying input stream.

Parameters:

listFile - the file to consider (may be null for reading information from loader)

loader - the class loader to load from

Returns:

the input stream

Throws:

IOException - in case of loading the startup sequence fails

load

private static List<StartupInfo> load(Reader reader)
                               throws IOException

Parameters:

reader - the reader providing access to the startup sequence

Returns:

the loaded startup information

Throws:

IOException - in case of loading the startup sequence fails

processLine

private static void processLine(String line,
 List<StartupInfo> startupSequence)

Processes a single line from the startup sequence file.

Parameters:

line - the line to be processed

startupSequence - the startup sequence to be modified as a side effect
