Method Detail

openPackage

public static OPCPackage openPackage(String path)
                              throws IOException

Wrapper to open a package, which works around shortcomings in java's this() constructor calls

Parameters:

path - the path to the document

Returns:

the new OPCPackage

Throws:

IOException - if there was a problem opening the document

getPackage

public OPCPackage getPackage()

Get the assigned OPCPackage

Returns:

the assigned OPCPackage

getCorePart

protected PackagePart getCorePart()

getRelatedByType

protected PackagePart[] getRelatedByType(String contentType)
                                  throws InvalidFormatException

Retrieves all the PackageParts which are defined as relationships of the base document with the specified content type.

Parameters:

contentType - the content type

Returns:

all the base document PackageParts which match the content type

Throws:

InvalidFormatException - when the relationships or the parts contain errors

See Also:

XSSFRelation, XSLFRelation, XWPFRelation, XDGFRelation

getProperties

public POIXMLProperties getProperties()

Get the document properties. This gives you access to the core ooxml properties, and the extended ooxml properties.

Returns:

the document properties

getAllEmbeddedParts

public abstract List<PackagePart> getAllEmbeddedParts()
                                               throws OpenXML4JException

Get the document's embedded files.

Returns:

the document's embedded files

Throws:

OpenXML4JException - if the embedded parts can't be determined

Since:

POI 4.0.0

load

protected final void load(POIXMLFactory factory)
                   throws IOException

Throws:

IOException

close

public void close()
           throws IOException

Closes the underlying OPCPackage from which this document was read, if there is one

Once this has been called, no further operations, updates or reads should be performed on the document.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException - for writable packages, if an IO exception occur during the saving process.

write

public final void write(OutputStream stream)
                 throws IOException

Write out this document to an OutputStream. Note - if the Document was opened from a File rather than an InputStream, you must write out to a different file, overwriting via an OutputStream isn't possible. If stream is a FileOutputStream on a networked drive or has a high cost/latency associated with each written byte, consider wrapping the OutputStream in a BufferedOutputStream to improve write performance.

Parameters:

stream - - the java OutputStream you wish to write the file to

Throws:

IOException - if anything can't be written.
