class TGrid: public TObject


TGrid

Abstract base class defining interface to common GRID services.

To open a connection to a GRID use the static method Connect().
The argument of Connect() is of the form:
<grid>[://<host>][:<port>], e.g.
alien, alien://alice.cern.ch, globus://glsvr1.cern.ch, ...
Depending on the <grid> specified an appropriate plugin library
will be loaded which will provide the real interface.

Related classes are TGridResult.

Function documentation

TGrid * Connect(const char* grid, const char* uid = 0, const char* pw = 0, const char* options = 0)
 The grid should be of the form:  <grid>://<host>[:<port>],
 e.g.:  alien://alice.cern.ch, globus://glsrv1.cern.ch, ...
 The uid is the username and pw the password that should be used for
 the connection. Depending on the <grid> the shared library (plugin)
 for the selected system will be loaded. When the connection could not
 be opened 0 is returned. For AliEn the supported options are:
 -domain=<domain name>
 -debug=<debug level from 1 to 10>
 Example: "-domain=cern.ch -debug=5"
