BOOL SGUsedBitmaps::IsMember (  Node *  pNode,
const StringBase &  strName
)  const [virtual]
 

Author:
Justin_Flude (Xara Group Ltd) <camelotdev@xara.com>
Date:
27/6/99
Parameters:
pNode --- the node to test for membership [INPUTS] strName --- the set value (name) to test for equality
Returns:
TRUE if the given node is a member of the given set within this group.
See also:
SGNameGroup::RegisterMember; SGNameItem::IsMember; CreateDisplayScan::CreateItems::Do
NB. the value returned as pBmp can sometimes be set to 1 rather than NULL. so for the meantime test for this too
