Subject: XDMFEntry commit
X-Git-Tag: v9.4.0-rc1~305^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1e9da7b88acb1ab99b7e4f63fa17a2f9de3eb824;p=dealii.git

XDMFEntry commit

Changed the constructors of XDMFEntry to allow for uint64_t datatypes
that we need for large data.  Changed some things in create_xdmf_entry
to match.
