getInternalZipFnameByExtension

public static java.lang.String getInternalZipFnameByExtension(java.lang.String extension,
                                              java.lang.String compressedFile)
                                                       throws java.lang.Exception

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

Throws:

java.lang.Exception

openFile

public static java.io.InputStream openFile(java.lang.String uri_string)
                                    throws java.net.URISyntaxException,
                                           java.io.IOException

Throws:

java.net.URISyntaxException

java.io.IOException

openFile

public static java.io.InputStream openFile(java.net.URI uri)
                                    throws java.io.IOException

Throws:

java.io.IOException

openFile

public static java.io.InputStream openFile(java.lang.String filePath,
                           java.lang.String compressedEntry)
                                    throws java.io.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:

java.io.IOException
