Whether the Directory's input Map is (globally) one to one.

This method should always be treated as a collective on all processes in the given communicator, which must be the same as the input Map's communicator. Not all implementations necessarily communicate.

inherited

Find process IDs and (optionally) local IDs for the given global IDs.

Precondition

nodeIDs.size() == globalIDs.size()

! computeLIDs || localIDs.size() == globalIDs.size()

Parameters

map	[in] The Directory's Map. This must be the same as given to the Directory's constructor. Directory may not keep a reference to the Map, in order to avoid circular references between a Map and its Directory.
globalIDs	[in] The global IDs for which to find process IDs (and optionally local IDs).
nodeIDs	[out] The process IDs corresponding to the given global IDs. If a global ID does not belong to any process, the corresponding entry of nodeIDs will be -1.
localIDs	[out] If computeLIDs is true, we fill this with the local IDs corresponding to the given global IDs. If a given global ID does not correspond to a local ID, the corresponding entry will be Teuchos::OrdinalTraits<LocalOrdinal>::invalid().
computeLIDs	[in] Whether to fill in localIDs.

Returns

If at least one GID was not present in the directory, return IDNotPresent. Otherwise, return AllIDsPresent.

Note

To implementers: The implementation of this method first performs input validation, then invokes getEntriesImpl() (implemented in the subclass) to do the work.
