QuickButCruddyTextExtractor (POI API Documentation)

java.lang.Object
- org.apache.poi.hslf.extractor.QuickButCruddyTextExtractor

```
public final class QuickButCruddyTextExtractor
extends java.lang.Object
```
This class will get all the text from a Powerpoint Document, including all the bits you didn't want, and in a somewhat random order, but will do it very fast. The class ignores most of the hslf classes, and doesn't use HSLFSlideShow. Instead, it just does a very basic scan through the file, grabbing all the text records as it goes. It then returns the text, either as a single string, or as a vector of all the individual strings. Because of how it works, it will return a lot of "crud" text that you probably didn't want! It will return text from master slides. It will return duplicate text, and some mangled text (powerpoint files often have duplicate copies of slide text in them). You don't get any idea what the text was associated with. Almost everyone will want to use @see PowerPointExtractor instead. There are only a very small number of cases (eg some performance sensitive lucene indexers) that would ever want to use this!
