What does it mean CTP and PPR?

问题

I starting figure out in apache.poi and I couldn't understand what does it mean CTP and PPr in XWPFParagraph. I have following code:

targetParagraph.getCTP()
               .setPPr(index.getParagraph().getCTP().getPPr());

I not found describing of this methods in official documentation apache.poi Can you explain to me what is it or get me some link where I can read about it?

Thanks for help!

回答1:

getCTP() returns org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP which from my understanding represends a paragraph on a lower level, strictly related to the xml. It is annotated as @Internal - it can be changed without much notice.

More of a guess but I'd say that getPPr() returns an object that represents a paragraph properties.

回答2:

Unfortunately there is not any documentation about the ooxml schemas, the low level basic objects of apache poi, public available. So we need downloading the sources of ooxml-schemas and then doing javadoc form those to get a API documentation which describes the classes and methods.

There we then find org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP, which is a paragraph in a Office Open XML word processing document and org.openxmlformats.schemas.wordprocessingml.x2006.main.CTPPr, which are paragraph properties in that kind of document.

Note ooxml-schemas version 1.4 is for usage together with apache poi 4.0.0 or newer. For older versions ooxml-schemas version 1.3 is needed.
