Method Details

loadPart

java.io.InputStream loadPart(java.lang.String partName) throws Docx4JException

Returns null if the part does not exist. This will happen when calling code optimistically tries to fetch a rels part (which may or may not exist). Note: JaxbXmlPart and JaxbXmlPartXPathAware both unmarshal lazily (ie can invoke this sometime after the docx is loaded). Caller (generally docx4j itself) should close the resulting InputStream after use.

Parameters:

partName -

Returns:

Throws:

Docx4JException

rename

void rename(PartName oldName, PartName newName)

Rename a part in the part store. Useful where a part is being renamed, but its content has not been loaded. (The existing approach is to manually force the content to be loaded)

Parameters:

oldName -

newName -

Since:

8.1.4

getPartSize

long getPartSize(java.lang.String partName) throws Docx4JException, java.lang.UnsupportedOperationException

The size of this part in bytes. Return -1 if the part does not exist.

Parameters:

partName -

Returns:

Throws:

Docx4JException

java.lang.UnsupportedOperationException

setOutputStream

void setOutputStream(java.io.OutputStream os) throws Docx4JException

Throws:

Docx4JException

saveContentTypes

void saveContentTypes(ContentTypeManager ctm) throws Docx4JException

Throws:

Docx4JException

saveJaxbXmlPart

void saveJaxbXmlPart(JaxbXmlPart part) throws Docx4JException

Throws:

Docx4JException

saveCustomXmlDataStoragePart

void saveCustomXmlDataStoragePart(CustomXmlDataStoragePart part) throws Docx4JException

Throws:

Docx4JException

saveXmlPart

void saveXmlPart(XmlPart part) throws Docx4JException

Throws:

Docx4JException

saveBinaryPart

void saveBinaryPart(Part part) throws Docx4JException

Throws:

Docx4JException

finishSave

void finishSave() throws Docx4JException

Anything necessary to perfect the save operation. For example,

Throws:

Docx4JException

setSourcePartStore

void setSourcePartStore(PartStore partStore)

Use in a save operation if the source part store (ie part store from which pkg loaded) is different to this target part store. In this case it is necessary to be able to fetch parts which hadn't need to have been loaded up until this point.

dispose

void dispose()
