EmptySource

java.lang.Object
- net.sf.saxon.lib.EmptySource

All Implemented Interfaces:

javax.xml.transform.Source
```
public class EmptySource
extends java.lang.Object
implements javax.xml.transform.Source
```
This class is an implementation of the JAXP Source interface. It represents a dummy Source, which resolves to an empty sequence. A URIResolver (called perhaps in furtherance of the doc() or document() function can choose to return an EmptySource for example if a URI is not accessible; the effect is that the call on doc() or document() returns an empty sequence. This may be useful to emulate the behaviour of earlier versions of XSLT.
The class is a singleton marker class.

public static EmptySource getInstance()
```
  - setSystemId
```
public void setSystemId(java.lang.String systemId)
```
    Set the system identifier for this Source. This is a dummy implementation to satisfy the interface, and it does nothing.
    
    Specified by:
    
    setSystemId in interface javax.xml.transform.Source
    
    Parameters:
    
    systemId - The system identifier as a URL string.

```
public java.lang.String getSystemId()
```
    Get the system identifier that was set with setSystemId.

    getSystemId in interface javax.xml.transform.Source
    
    Returns:
    
    null (always). The class is stateless.
