public class SpaceFinder
extends Object

 This utility class provides accessing to Container proxy
 or Space proxy (IJSpace).

  The SpaceFinder is designed to provide a unified interface for finding a
 space/container in each of the mode specified.
 In addition to the lookup option there is another option of finding the space
 via its container.
  To provide a unified manager of accessing the space in any of the above modes
 we will use a url based interface which will provide the information of the
 protocol and the address of the space that should be found.

 The general format for this URL is as follows:

 Protocol://[host]:[port]/[container_name]/[space_name]?[query_string]

 Protocol: [ rmi | jini | java ]
           The "java" protocol enables working with an embedded space. When choosing so
           one should specify in the query string one of three space operations:

           > create - to create a new space
            example of "mySpace" space creation:

            java://myHost/myContinaer/mySpace?create

           > open - To open  an existing space in an embedded mode:
            example of opening "mySpace" space:

            java://myHost/myContinaer/mySpace?open

           > destroy - for destroy  an existing space:
            example of destroying "mySpace" space:

            java://myHost/myContinaer/mySpace?destroy

 Host: The host name. Can be '*', when JINI is used as a protocol, the host
       value determines whether to use Unicast or Multicast.

 Port: the registry or lookup port. If the port is  not specified,
       the default port 10098 will be used.

 Container Name: The name of the container, which holds the space.
                 If the container name is '*' then the container attribute will be ignored and
 the
                 space will be looked for directly regardless of the container that holds it .

 Examples of space url's:

 1. Looking for a space using JINI Unicast protocol.
    jini://mylookuphost/mycontainername/myspace
  Or
    jini://*/*/myspace

 2. Looking for a space using the JINI multicast protocol.
    jini://*/containername/myspace
  Or
    jini://*/*/myspace

 3. looking for a container regardless of the space it contains in any of the above methods:
    jini://mylookuphost/mycontainername
    jini://*/mycontainername

Deprecated.

Verifies for validation if the specified url is valid and returns SpaceURL object that contains all information about specified url. This method also support multiple URLs separate by ";"

Parameters:

url - The url to verify.

Returns:

Returns SpaceURL object that contains all information about specified url.
