Summary: Xerces C++ rtti requirement.
Key: XERCESC-2157
URL: https://issues.apache.org/jira/browse/XERCESC-2157
Project: Xerces-C++
Issue Type: Wish
Affects Versions: 3.2.2
Reporter: Philip Armstrong
Attachments:
0001-Change-dynamic_casts-to-virtual-methods-to-avoid-the.patch
The change introduced in XERCESC-2088 - Fix undefined casting behavior in DOM
means that Xerces now requires rtti to build. Previously Xerces made a point of
not requiring rtti and this was one of the reasons we used it.
As requested in the comments to that issue, attached is a small patch which
shows our approach to eliminating the need for rtti, whilst keeping the same
semantics in the code. The downside of this approach is that it a) requires a
bunch of virtual methods added to DOMNode and probably more importantly b) also
requires that any classes that inherit from both DOMNode and one of the
HasXXXImpl classes must override the appropriate methods.--
Obviously b) especially is not ideal, but without refactoring the code to
remove the multiple inheritance from both DOMNode and HasXXXImpl classes, this
seemed to be the least invasive change that would allow us to continue building
with no-rtti.
