All Implemented Interfaces:

TopicMapReaderIF
```
public class RDFTopicMapReader
extends Object
implements TopicMapReaderIF

  - read
```
public TopicMapIF read()
                throws IOException
```
    Description copied from interface: TopicMapReaderIF
    
    PUBLIC: Reads the next topic map available from some implicit, implementation dependent source.
    A topic map source may contain multiple topic maps. The read method returns the next topic map that is available from that source. null is returned when there are no more topic maps available. In a sense this is iterator-like behaviour.
    
    Specified by:
    
    read in interface TopicMapReaderIF
    
    Returns:
    
    The next topic map read from the source; an object implementing TopicMapIF. null is returned when there are no more topic maps available from the source.
    
    Throws:
    
    IOException - Thrown if reading the source fails.
  - readAll
```
public Collection readAll()
                   throws IOException
```
    Description copied from interface: TopicMapReaderIF
    
    PUBLIC: Reads all the topic map available from some implicit, implementation dependent source.
    A topic map source may contain multiple topic maps. The readAll method returns a collection contain all the topic maps available from the source.
    
    Specified by:
    
    readAll in interface TopicMapReaderIF
    
    Returns:
    
    A collection containing all the topic maps read from the source; objects implementing TopicMapIF.
    
    Throws:
    
    IOException - Thrown if reading the source fails.
  - importInto
```
public void importInto(TopicMapIF topicmap)
                throws IOException
```
    Description copied from interface: TopicMapReaderIF
    
    PUBLIC: Imports an implicitly designated topic map into the given topic map.
    
    Specified by:
    
    importInto in interface TopicMapReaderIF
    
    Parameters:
    
    topicmap - The topic map into which the import will be done; an object implementing TopicMapIF.
    
    Throws:
    
    IOException
  - setAdditionalProperties
```
public void setAdditionalProperties(Map<String,Object> properties)
```
    Sets additional RDFTopicMapReader properties. Accepts the following properties:
    - 'duplicateSuppression' (Boolean), corresponds to setDuplicateSuppression(boolean)
    - 'generateNames' (Boolean), corresponds to setGenerateNames(boolean)

    - 'mappingFile' (File), corresponds to setMappingFile(java.io.File)
    - 'mappingURL' (String), corresponds to #setMappingURL(java.lang.String)
    - 'mappingSyntax' (String), sets the syntax to use in combination with setMappingFile(java.io.File) and #setMappingURL(java.lang.String)
