- Method Detail
  - getRootElement
```
SourceElement getRootElement()
                      throws SourceException
```
    Returns the root element of the source.
    
    Returns:
    
    the root element of the source, not null.
    
    Throws:
    
    SourceException - if the source cannot be constructed.
  - getDescription
```
String getDescription()
```
    Gets a description of this source for debugging purposes.
    
    Returns:
    
    the description, which should make it possible to identify the currently processed output.
  - getSourceFile
```
File getSourceFile()
```
    Returns the source file, if it exists.
    
    Returns:
    
    the source file, or null if the source is not read from a file.
  - getLastModified
```
Date getLastModified()
```
    Returns the date when the source was last modified.
    
    Returns:
    
    the last modification date, or null when unknown.
  - getContentChecksum
```
byte[] getContentChecksum()
```
    Returns the checksum of the content of the source. It is not defined which checksum is returned, the only requirement is that collisions should be extremely rare, i.e it can be assumed that if the checksum is the same, the content is also the same.
    
    Returns:
    
    the checksum of the content of the source, or null if it cannot be determined.
