exists()

bool ossim::CurlStreamFactory::exists ( const std::string &  connectionString, bool &  continueFlag  ) const

virtual

Methods to test if connection exists.

Parameters

connectionString
continueFlag	Initializes by this, if set to false, indicates factory handles file/url and no more factory checks are necessary. If true, connection is not handled by this factory.

Returns

true on success, false, if not.
