Subject: Refactor the TextPropCollection and TextProp classes into their own model package... 
X-Git-Tag: REL_3_0_RC1~32
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=5c518687f598be7696de7c424f1e5fbb69617a1e;p=poi.git

Refactor the TextPropCollection and TextProp classes into their own model package. Some of the logic in StyleTextPropAtom should probably be refactored out too, but that's still to do

git-svn-id: https://svn.apache.org/repos/asf/jakarta/poi/trunk@496405 13f79535-47bb-0310-9956-ffa450edef68
