StreamSource (Java Platform SE 8 )

java.lang.Object
- javax.xml.transform.stream.StreamSource

All Implemented Interfaces:

Source
```
public class StreamSource
extends Object
implements Source
```
Acts as an holder for a transformation Source in the form of a stream of XML markup.

Note: Due to their internal use of either a Reader or InputStream instance, StreamSource instances may only be used once.

public StreamSource()
```
    Zero-argument default constructor. If this constructor is used, and no Stream source is set using setInputStream(java.io.InputStream inputStream) or setReader(java.io.Reader reader), then the Transformer will create an empty source InputStream using new InputStream().
    
    See Also:
    
    Transformer.transform(Source xmlSource, Result outputTarget)
  - StreamSource
```
public StreamSource(InputStream inputStream)
```
    Construct a StreamSource from a byte stream. Normally, a stream should be used rather than a reader, so the XML parser can resolve character encoding specified by the XML declaration.
    If this constructor is used to process a stylesheet, normally setSystemId should also be called, so that relative URI references can be resolved.
    
    Parameters:
    
    inputStream - A valid InputStream reference to an XML stream.
  - StreamSource
```
public StreamSource(InputStream inputStream,
                    String systemId)
```
    Construct a StreamSource from a byte stream. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration.
    This constructor allows the systemID to be set in addition to the input stream, which allows relative URIs to be processed.
    
    Parameters:
    
    inputStream - A valid InputStream reference to an XML stream.
    
    systemId - Must be a String that conforms to the URI syntax.
  - StreamSource
```
public StreamSource(Reader reader)
```
    Construct a StreamSource from a character reader. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration. However, in many cases the encoding of the input stream is already resolved, as in the case of reading XML from a StringReader.
    
    Parameters:
    
    reader - A valid Reader reference to an XML character stream.
  - StreamSource
```
public StreamSource(Reader reader,
                    String systemId)
```
    Construct a StreamSource from a character reader. Normally, a stream should be used rather than a reader, so that the XML parser may resolve character encoding specified by the XML declaration. However, in many cases the encoding of the input stream is already resolved, as in the case of reading XML from a StringReader.
    
    Parameters:
    
    reader - A valid Reader reference to an XML character stream.
    
    systemId - Must be a String that conforms to the URI syntax.
  - StreamSource
```
public StreamSource(String systemId)
```
    Construct a StreamSource from a URL.
    
    Parameters:
    
    systemId - Must be a String that conforms to the URI syntax.
  - StreamSource
```
public StreamSource(File f)
```
    Construct a StreamSource from a File.
    
    Parameters:
    
    f - Must a non-null File reference.
- Method Detail
  - setInputStream
```
public void setInputStream(InputStream inputStream)
```
    Set the byte stream to be used as input. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration.
    If this Source object is used to process a stylesheet, normally setSystemId should also be called, so that relative URL references can be resolved.
    
    Parameters:
    
    inputStream - A valid InputStream reference to an XML stream.
  - getInputStream
```
public InputStream getInputStream()
```
    Get the byte stream that was set with setByteStream.
    
    Returns:
    
    The byte stream that was set with setByteStream, or null if setByteStream or the ByteStream constructor was not called.
  - setReader
```
public void setReader(Reader reader)
```
    Set the input to be a character reader. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration. However, in many cases the encoding of the input stream is already resolved, as in the case of reading XML from a StringReader.
    
    Parameters:
    
    reader - A valid Reader reference to an XML CharacterStream.
  - getReader
```
public Reader getReader()
```
    Get the character stream that was set with setReader.
    
    Returns:
    
    The character stream that was set with setReader, or null if setReader or the Reader constructor was not called.
  - setPublicId
```
public void setPublicId(String publicId)
```
    Set the public identifier for this Source.
    The public identifier is always optional: if the application writer includes one, it will be provided as part of the location information.
    
    Parameters:
    
    publicId - The public identifier as a string.
  - getPublicId
```
public String getPublicId()
```
    Get the public identifier that was set with setPublicId.
    
    Returns:
    
    The public identifier that was set with setPublicId, or null if setPublicId was not called.
  - setSystemId
```
public void setSystemId(String systemId)
```
    Set the system identifier for this Source.
    The system identifier is optional if there is a byte stream or a character stream, but it is still useful to provide one, since the application can use it to resolve relative URIs and can include it in error messages and warnings (the parser will attempt to open a connection to the URI only if there is no byte stream or character stream specified).
    
    Specified by:
    
    setSystemId in interface Source
    
    Parameters:
    
    systemId - The system identifier as a URL string.
  - getSystemId
```
public String getSystemId()
```
    Get the system identifier that was set with setSystemId.
    
    Specified by:
    
    getSystemId in interface Source
    
    Returns:
    
    The system identifier that was set with setSystemId, or null if setSystemId was not called.
  - setSystemId
```
public void setSystemId(File f)
```
    Set the system ID from a File reference.
    
    Parameters:
    
    f - Must a non-null File reference.
