Method Detail

initialize

void initialize(String file)
                throws IOException

Construct a new POI filesystem around the given file.

Throws:

IOException - if an error occurred when opening the file.

initialize

void initialize(RandomAccessInputStream stream)
                throws IOException

Construct a new POI filesystem around the given stream.

Throws:

IOException - if an error occurred when reading from the stream.

getInputStream

InputStream getInputStream(String file)
                           throws IOException

Retrieve an InputStream corresponding to the given file name. Either of the 'initialize' methods must be called before this method.

Parameters:

file - The name of the embedded file for which to retrieve an InputStream.

Throws:

IOException - if an error occurred when reading the file

getDocumentStream

RandomAccessInputStream getDocumentStream(String file)
                                          throws IOException

Retrieve a RandomAccessInputStream corresponding to the given file name. Either of the 'initialize' methods must be called before this method.

Parameters:

file - The name of the embedded file for which to retrieve a RandomAccessInputStream.

Throws:

IOException - if an error occurred when reading the file

getDocumentBytes

byte[] getDocumentBytes(String file)
                        throws IOException

Retrieve all of the raw bytes that correspond to the given file name. Either of the 'initialize' methods must be called before this method.

Parameters:

file - The name of the embedded file for which to retrieve bytes.

Throws:

IOException - if an error occurred when reading the file

getDocumentBytes

byte[] getDocumentBytes(String file,
                      int length)
                        throws IOException

Retrieve at most 'length' bytes that correspond to the given file name. Either of the 'initialize' methods must be called before this method.

Parameters:

file - The name of the embedded file for which to retrieve bytes.

Throws:

IOException - if an error occurred when reading the file

getFileSize

int getFileSize(String file)

Retrieve the total number of bytes in the given file. Either of the 'initialize' methods must be called before this method.

Parameters:

file - The name of the embedded file.

Throws:

IOException - if an error occurred when reading the file

getDocumentList

Vector<String> getDocumentList()

Retrieve a list of all files in the current POI file system.

close

void close()
           throws IOException

Close the current POI file system.

Throws:

IOException
