org.apache.directory.server.core.api.normalization.FilterNormalizingVisitor
A filter visitor which normalizes leaf node values as it visits them. It also removes leaf nodes from branches whose attributeType is undefined. It obviously cannot remove a leaf node from a filter which is only a leaf node. Checks to see if a filter is a leaf node with undefined attributeTypes should be done outside this visitor. Since this visitor may remove filter nodes it may produce negative results on filters, like NOT branch nodes without a child or AND and OR nodes with one or less children. This might make some partition implementations choke. To avoid this problem we clean up branch nodes that don't make sense. For example all BranchNodes without children are just removed. An AND and OR BranchNode with a single child is replaced with it's child for all but the topmost branch node which we cannot replace. So again the top most branch node must be inspected by code outside of this visitor. @author Apache Directory Project
