## Class VHostItem

- java.lang.Object
- - tigase.db.comp.RepositoryItemAbstract
  - - tigase.vhosts.VHostItem

- All Implemented Interfaces:
    Comparable<VHostItem>, RepositoryItem

      public class VHostItem
      extends RepositoryItemAbstract
      implements Comparable<VHostItem>

  Objects of this class represent virtual host with all hosts configuration settings. In most cases simple domain name string is not enough to deal with the virtual host. VHost can be enabled/disabled. Can be available to selected server components only and so on. Therefore every time there is a detailed information needed for a vhost this classed must be used. This class has it's own XML representation which can be used for creating an instance of the class or can be exported to the XML form for permanent storage: `<vhost hostname="vhost.something.com" enabled="true" anon="true" register="true" max-users="99999999999L"> <comps/> <other/>` From the init.property file it is also possible to set additional parameters for the vhost. By default everything is enabled and max accounts set to unlimited. In the example below we configure 2 domains: devel.tigase.org and test.tigase.org. For the first domain there are no additional settings, hence the domain has everything on by default, whereas the second has everything switched off and max user accounts set to 100.

       --virt-hosts = devel.tigase.org,test.tigase.org:-anon:-register:max-users=100

  It also possible to set forwarding for the domain:

       --virt-hosts = test.tigase.org:pres-forw=lpart@domain/res:mess-forw=lpart@domain/res

  Please note, forwarding address set this way cannot contain any of characters: [,:=] The order features are set for domain is unimportant. Created: 22 Nov 2008

    - #### initFromPropertyString

          public void initFromPropertyString(String propString)

      Description copied from interface: `RepositoryItem`
      The item can be initialized based on the data loaded from a configuration file. In such a case the item representation is usually very simplified as a list of parameters separated by a marker. Please note, usually each item is separated from another with a comma, therefore do not use a comma in the item property string. Double collon is commonly used alternative.
      Specified by:
        `initFromPropertyString` in interface `RepositoryItem`
      Parameters:
        `propString` - is a property string to initialize the RepositoryItem.

    - #### toElement

          public Element toElement()
