Here is the call graph for this function:

template<typename RwCatalogMgr , typename RoCatalogMgr >
bool receiver::CatalogMergeTool< RwCatalogMgr, RoCatalogMgr >::IsIgnoredPath ( const PathString &  )
protectedvirtual

Check if a path (and, by implication, any subpath) should be ignored and not considered for comparison purposes.

This can be used to avoid unnecessary work by avoiding recursion into paths that will not be of interest (e.g. paths that are neither above nor within the lease path, when using a gateway).

Reimplemented from CatalogDiffTool< RoCatalogMgr >.

Here is the call graph for this function:

template<typename RwCatalogMgr , typename RoCatalogMgr >
bool receiver::CatalogMergeTool< RwCatalogMgr, RoCatalogMgr >::IsReportablePath ( const PathString &  )
protectedvirtual

Check if a difference found on a path should be reported via ReportAddition(), ReportRemoval(), or ReportModification().

This can be used to filter out differences that are not of interest (e.g. paths that are not within the lease path, when using a gateway).

Note that an ignored path must necessarily be a non-reportable path, since an ignored path will never even be compared (and so can never be reported upon). However, there do exist paths that are neither ignored nor reportable: when using a gateway, a parent of the lease path is not reportable (since it is not within the lease path) but must not be ignored (since we need to recurse into the parent path in order to reach the lease path).

As a concrete example, with a lease path of /foo/bar:

/foo <- not ignored, not reportable /foo/bar <- not ignored reportable /foo/bar/thing <- not ignored reportable /foo/baz <- ignored (and therefore not reportable)
