Example 1

 C_OBJECT($info)

 

 $info:=ds.getInfo() //Executed on 4D Server or 4D

  //{"type":"4D","networked":false,"localID":""}

 

 $info:=ds.getInfo() // Executed on 4D remote

  //{"type":"4D Server","networked":true,"localID":""}

Example 2

On a remote datastore:

 C_OBJECT($info;$connectTo;$remoteDS)

 

 $connectTo:=New object("hostname";"111.222.33.44:8044";"user";"marie";"password";"aaaa")

 $remoteDS:=Open datastore($connectTo;"students")

 $info:=$remoteDS.getInfo()

 

  //{"type":"4D Server",

  //"localID":"students",

  //"networked":true,

  //"connection":{hostname:"111.222.33.44:8044","tls":false,"idleTimeout":2880,"user":"marie"}}
