Class EventWorkbookBuilder

    java.lang.Object
      org.apache.poi.hssf.eventusermodel.EventWorkbookBuilder

    public class EventWorkbookBuilder

extends java.lang.Object

When working with the EventUserModel, if you want to process formulas, you need an instance of `InternalWorkbook` to pass to a `HSSFWorkbook`, to finally give to `HSSFFormulaParser`, and this will build you stub ones. Since you're working with the EventUserModel, you wouldn't want to get a full `InternalWorkbook` and `HSSFWorkbook`, as they would eat too much memory. Instead, you should collect a few key records as they go past, then call this once you have them to build a stub `InternalWorkbook`, and from that a stub `HSSFWorkbook`, to use with the `HSSFFormulaParser`. The records you should collect are: * `ExternSheetRecord` * `BoundSheetRecord` You should probably also collect `SSTRecord`, but it's not required to pass this in. To help, this class includes a HSSFListener wrapper that will do the collecting for you.

Nested Class Summary
`static class` `EventWorkbookBuilder.SheetRecordCollectingListener` A wrapping HSSFListener which will collect `BoundSheetRecord`s and `ExternSheetRecord`s as they go past, so you can create a Stub `InternalWorkbook` from them once required.
