- Constructor Detail
  - CompositeTripleHandler
```
public CompositeTripleHandler()
```
    Constructor with empty decorated list.
  - CompositeTripleHandler
```
public CompositeTripleHandler(Collection<TripleHandler> children)
```
    Constructor with initial list of decorated handlers.
    
    Parameters:
    
    children - list of decorated handlers.
- Method Detail
  - addChild
```
public void addChild(TripleHandler child)
```
    Adds a decorated handler.
    
    Parameters:
    
    child - the decorated handler.
  - getChilds
```
public Collection<TripleHandler> getChilds()
```
  - startDocument
```
public void startDocument(org.eclipse.rdf4j.model.IRI documentIRI)
 throws TripleHandlerException 
```
    Specified by:
    
    startDocument in interface TripleHandler
    
    Throws:
    
    TripleHandlerException
  - openContext
```
public void openContext(ExtractionContext context)
 throws TripleHandlerException 
```
    Description copied from interface: TripleHandler
    
    Informs the handler that a new context has been established. Contexts are not guaranteed to receive any triples, so they might be closed without any triple.
    
    Specified by:
    
    openContext in interface TripleHandler
    
    Parameters:
    
    context - an instantiated ExtractionContext
    
    Throws:
    
    TripleHandlerException - if there is an errr opening the ExtractionContext
  - closeContext
```
public void closeContext(ExtractionContext context)
 throws TripleHandlerException 
```
    Description copied from interface: TripleHandler
    
    Informs the handler that no more triples will come from a previously opened context. All contexts are guaranteed to be closed before the final close(). The document context for each document is guaranteed to be closed after all local contexts of that document.
    
    Specified by:
    
    closeContext in interface TripleHandler
    
    Parameters:
    
    context - the context to be closed.
    
    Throws:
    
    TripleHandlerException - if there is an error closing the ExtractionContext.
  - receiveTriple
```
public void receiveTriple(org.eclipse.rdf4j.model.Resource s,
 org.eclipse.rdf4j.model.IRI p,
 org.eclipse.rdf4j.model.Value o,
 org.eclipse.rdf4j.model.IRI g,
 ExtractionContext context)
 throws TripleHandlerException 
```
    Description copied from interface: TripleHandler
    
    Invoked with a currently open context, notifies the detection of a triple.
    
    Specified by:
    
    receiveTriple in interface TripleHandler
    
    Parameters:
    
    s - triple subject, cannot be null.
    
    p - triple predicate, cannot be null.
    
    o - triple object, cannot be null.
    
    g - triple graph, can be null.
    
    context - extraction context.
    
    Throws:
    
    TripleHandlerException - if there is an error receiving the triple.
  - receiveNamespace
```
public void receiveNamespace(String prefix,
 String uri,
 ExtractionContext context)
 throws TripleHandlerException 
```
    Description copied from interface: TripleHandler
    
    Invoked with a currently open context, notifies the detection of a namespace.
    
    Specified by:
    
    receiveNamespace in interface TripleHandler
    
    Parameters:
    
    prefix - namespace prefix.
    
    uri - namespace IRI.
    
    context - namespace context.
    
    Throws:
    
    TripleHandlerException - if there is an error receiving the namespace.
  - close
```
public void close()
 throws TripleHandlerException 
```
    Description copied from interface: TripleHandler
    
    Will be called last and exactly once.
    
    Specified by:
    
    close in interface AutoCloseable
    
    Specified by:
    
    close in interface TripleHandler
    
    Throws:
    
    TripleHandlerException - if there is an error closing the TripleHandler implementation.
  - endDocument
```
public void endDocument(org.eclipse.rdf4j.model.IRI documentIRI)
 throws TripleHandlerException 
```
    Description copied from interface: TripleHandler
    
    Informs the handler that the end of the document has been reached.
    
    Specified by:
    
    endDocument in interface TripleHandler
    
    Parameters:
    
    documentIRI - document IRI.
    
    Throws:
    
    TripleHandlerException - if there is an error ending the document.
  - setContentLength
```
public void setContentLength(long contentLength)
```
    Description copied from interface: TripleHandler
    
    Sets the length of the content to be processed.
    
    Specified by:
    
    setContentLength in interface TripleHandler
    
    Parameters:
    
    contentLength - length of the content being processed.
