Bug ID: 58651
Summary: Replace all O(N^2) usage of getting merged regions on
a sheet
Product: POI
Version: 3.14-dev
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P2
Component: SS Common
Assignee: [email protected]
Reporter: [email protected]
Depends on: 57893
Sheet.getMergedRegions() was added in POI 3.13 for bug 57893, which has O(n)
running time. Prior to this, functions used a for-loop around
Sheet.getMergedRegion(i), which had poor performance on both HSSF and XSSF.
SheetUtil and perhaps other files haven't been updated yet to use the more
efficient code.
