- Constructor Detail
  - TopicInfo
```
public TopicInfo(java.lang.String topicName)
```
    The public constructor creates a TopicInfo object with the given name. The topic is not created on the server until the object is passed to TibjmsAdmin.createTopic().
    
    Parameters:
    
    topicName - The name for the topic being created.
- Method Detail
  - getExportTransports
```
public java.lang.String[] getExportTransports()
```
    Get the names of the transports that this topic exports messages on.
    
    Returns:
    
    array of transport names.
  - areExportTransportsInherited
```
@Deprecated
public boolean areExportTransportsInherited()
```
    Deprecated.
    This method has been misnamed and replaced by isExportTransportsInherited().
  - isExportTransportsInherited
```
public boolean isExportTransportsInherited()
```
    Determines if the list of transports this topic exports messages on was inherited from a parent topic or whether it was set on the topic directly.
    
    Returns:
    
    true if transport list is inherited from parent, false otherwise.
    
    Since:
    
    EMS 4.4
  - addExportTransport
```
public void addExportTransport(java.lang.String transportName)
                        throws TibjmsAdminInvalidNameException
```
    Add a new export transport to the list of transports this destination exports messages to. If the current list of transports has been inherited from a parent topic then adding a transport will stop the inheritance and the inherited transports will all be removed from the list and replaced with the new one. From then on isExportTransportsInherited will indicate that the transports are no longer inherited and future calls to addExportTransport will simply add new transports to the list.
    
    Parameters:
    
    transportName - the name of the transport.
    
    Throws:
    
    TibjmsAdminInvalidNameException - if transportName is not a legal transport name
  - removeExportTransport
```
public void removeExportTransport(java.lang.String transportName)
                           throws TibjmsAdminInvalidNameException,
                                  TibjmsAdminException
```
    Remove an export transport from the list of transports this destination exports messages to. The removal of a transport from the list if the transports is inherited from a parent topic is not permitted and results in an exception.
    
    Parameters:
    
    transportName - the name of the transport.
    
    Throws:
    
    TibjmsAdminInvalidNameException - if transportName is not a legal transport name
    
    TibjmsAdminException - if export transports is inherited
  - getSubscriptionCount
