(Re)loads the static configuration information from the specified file.
This method is called implicitly on ClassLoad, but it may be
called explicitly to change the Configuration used for the purpose
of testing - in which case it should be called prior to initializing
a SolrCore.
This method should only be called for testing purposes.
Because it modifies a singleton, it is not suitable for running
multi-threaded tests.
Parameters: file - file name to load See Also: Config.openResource |
