```
public interface RDFStream
extends java.io.Closeable
```
A simple interface for representing a stream for RDF input. An RDF stream is typically backed by an input stream and parsed with an RDFParser but a specific stream implementation might use different means to generate statements.

void parse(RDFHandler theHandler)
    throws java.io.IOException,
           InvalidRDF,
           RDFHandlerException
```
    Parses the stream and passes the statements to the given handler.
    
    Throws:
    
    java.io.IOException
    
    InvalidRDF
    
    RDFHandlerException
  - getContext
```
Resource getContext()
```
    Returns the default context associated with this stream or null if there is no default context. Note that, the statements that will be sent to the handler may not be using this context and the user of this stream should make sure the context information is used correctly.
  - hasContext
```
boolean hasContext()
```
    Returns true either if this stream has a non-null context or the statements generated by this stream has contexts.
  - getName
```
java.lang.String getName()
```
    Returns the name of this stream. If the stream is backed by a file this will return the file's name. Otherwise it might be an auto-generated name or some other (not necessarily unique) name.
  - bytesRead
```
long bytesRead()
```
  - length
```
long length()
```
  - estimatedCount
```
long estimatedCount()
