[M2.8]: When adding a new part to a package, the package implementer shall ensure that a content type for that part is specified in the Content Types stream; the package implementer shall perform the steps described in §9.1.2.3:

1. Get the extension from the part name by taking the substring to the right of the rightmost occurrence of the dot character (.) from the rightmost segment.

2. If a part name has no extension, a corresponding Override element shall be added to the Content Types stream.

3. Compare the resulting extension with the values specified for the Extension attributes of the Default elements in the Content Types stream. The comparison shall be case-insensitive ASCII.

4. If there is a Default element with a matching Extension attribute, then the content type of the new part shall be compared with the value of the ContentType attribute. The comparison might be case-sensitive and include every character regardless of the role it plays in the content-type grammar of RFC 2616, or it might follow the grammar of RFC 2616.

a. If the content types match, no further action is required.

b. If the content types do not match, a new Override element shall be added to the Content Types stream. .

5. If there is no Default element with a matching Extension attribute, a new Default element or Override element shall be added to the Content Types stream.

Add an override content type for a specific part. @param partName Name of the part. @param contentType Content type of the part. Add a content type associated with the specified extension. @param extension The part name extension to bind to a content type. @param contentType The content type associated with the specified extension.

Delete a content type based on the specified part name. If the specified part name is register with an override content type, then this content type is remove, else the content type is remove in the default content type list if it exists and if no part is associated with it yet.

Check rule M2.4: The package implementer shall require that the Content Types stream contain one of the following for every part in the package: One matching Default element One matching Override element Both a matching Default element and a matching Override element, in which case the Override element takes precedence.

@param partName The part URI associated with the override content type to delete. @exception InvalidOperationException Throws if
Check if the specified content type is already register. @param contentType The content type to check. @return true if the specified content type is already register, then false. Get the content type for the specified part, if any.

Rule [M2.9]: To get the content type of a part, the package implementer shall perform the steps described in §9.1.2.4:

1. Compare the part name with the values specified for the PartName attribute of the Override elements. The comparison shall be case-insensitive ASCII.

2. If there is an Override element with a matching PartName attribute, return the value of its ContentType attribute. No further action is required.

3. If there is no Override element with a matching PartName attribute, then a. Get the extension from the part name by taking the substring to the right of the rightmost occurrence of the dot character (.) from the rightmost segment. b. Check the Default elements of the Content Types stream, comparing the extension with the value of the Extension attribute. The comparison shall be case-insensitive ASCII.

4. If there is a Default element with a matching Extension attribute, return the value of its ContentType attribute. No further action is required.

5. If neither Override nor Default elements with matching attributes are found for the specified part name, the implementation shall not map this part name to a part.

@param partName The URI part to check. @return The content type associated with the URI (in case of an override content type) or the extension (in case of default content type), else null. @exception OpenXml4NetRuntimeException Throws if the content type manager is not able to find the content from an existing part.

A typical scneario to call this method is to rename a template file to the main format, e.g. ".dotx" to ".docx" ".dotm" to ".docm" ".xltx" to ".xlsx" ".xltm" to ".xlsm" ".potx" to ".pptx" ".potm" to ".pptm"

For example, a code converting a .xlsm macro workbook to .xlsx would look as follows:


            
                 OPCPackage pkg = OPCPackage.open(new FileInputStream("macro-workbook.xlsm"));
                 pkg.replaceContentType(
                     "application/vnd.ms-excel.sheet.macroEnabled.main+xml",
                     "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.main+xml");
            
                 FileOutputStream out = new FileOutputStream("workbook.xlsx");
                 pkg.save(out);
                 out.close();

Allows you to get at the ZipEntries, without needing to worry about ZipFile vs ZipInputStream being annoyingly very different. Returns an InputStream of the decompressed data that makes up the entry Indicates we are done with reading, and resources may be freed Returns an Enumeration of all the Entries A ZipEntrySource wrapper around a ZipFile. Should be as low in terms of memory as a normal ZipFile implementation is. Provides a way to get at all the ZipEntries from a ZipInputStream, as many times as required. Allows a ZipInputStream to be treated much like a ZipFile, for a price in terms of memory. Be sure to call {@link #close()} as soon as you're done, to free up that memory! Reads all the entries from the ZipInputStream into memory, and closes the source stream. We'll then eat lots of memory, but be able to work with the entries at-will. Why oh why oh why are Iterator and Enumeration still not compatible? So we can close the real zip entry and still effectively work with it. Holds the (decompressed!) data in memory, so close this as soon as you can!
