Examples of org.docx4j.openpackaging.parts.Part

org.docx4j.openpackaging.parts.Part
An abstraction of an Open Packaging Convention (OPC) Part. OPC Parts are either XML, or binary (or text) documents. Most are XML documents. docx4j aims to represent XML parts using JAXB. We have JAXB representations for all the common parts. To instantiate a Part use (or create) an appropriate subclass. When an existing document is being loaded, ContentTypeManager.getPart will instantiate the appropriate subclass.
