Method Detail

getInternalZipFnameByExtension

public static String getInternalZipFnameByExtension(String extension,
                                                    String compressedFile)
                                             throws Exception

Deprecated.

only used by very old data readers which only deliver the first file in zip file [ede 05.2012]

Searches through the .zip file looking for a file with the given extension. Returns null if it doesn't find one.

Throws:

Exception

listEntries

public static List<URI> listEntries(File file)
                             throws Exception

Throws:

Exception

openFile

public static InputStream openFile(String uri_string)
                            throws URISyntaxException,
                                   IOException

Throws:

openFile

public static InputStream openFile(URI uri)
                            throws IOException

Throws:

IOException

openFile

public static InputStream openFile(String filePath,
                                   String compressedEntry)
                            throws IOException

Utility file open function - handles compressed and un-compressed files.

Parameters:

filePath - name of the file to search for.

compressedEntry - name of the compressed file.

If compressedEntry = null, opens a FileInputStream on filePath

If filePath ends in ".zip" - opens the compressed Zip and looks for the file called compressedEntry

If filePath ends in ".gz" - opens the compressed .gz file.

Throws:

IOException
