Detailed Description

OSG Visitor class which pages the highest level of detail of paged LOD nodes in.

This is a base class, intended to be overridden. This base class will cause paging in of every paged LOD node. Subclasses may be more selective by overriding requiresPageIn().

Returns

True if this node should be paged in. This is overridden in subclasses, depending on how the paging is being implemented. Default implementation returns true, which pages in the entire database.

Reimplemented in DtGeometryPageInVisitor.
