## edu.harvard.hul.ois.jhove.handler
Class AuditHandler

    java.lang.Object
      edu.harvard.hul.ois.jhove.HandlerBase
          edu.harvard.hul.ois.jhove.handler.XmlHandler
              edu.harvard.hul.ois.jhove.handler.AuditHandler

All Implemented Interfaces:
  OutputHandler

    public class AuditHandler

extends XmlHandler

JHOVE audit output handler, derived from the standard JHOVE XML handler. It is expected that this class will be used as the parent for other, more interesting output handlers. Subclasses should override the implementations of the Impl methods, e.g., endDirectoryImpl ().

Constructor Detail

### AuditHandler

    public AuditHandler()

  Instantiate a `AudiHandler` object.

Method Detail

### endDirectory

    public final void endDirectory()

  Callback indicating a directory is finished being processed. Prop the state stack and place the current directory file count into the directory hash.

  Specified by:
    `endDirectory` in interface `OutputHandler`
  Overrides:
    `endDirectory` in class `HandlerBase`

### endDirectoryImpl

    public void endDirectoryImpl(AuditState state)

  Local extension to the standard callback indicating a directory is finished being processed.

  Parameters:
    `state` - Audit handler state

### okToProcess

    public final boolean okToProcess(java.lang.String filepath)

  Determine whether or not to process the file.

  Specified by:
    `okToProcess` in interface `OutputHandler`
  Overrides:
    `okToProcess` in class `HandlerBase`
  Parameters:
    `filepath` - File pathname

### okToProcessImpl

    public boolean okToProcessImpl(java.lang.String filepath,
                                   AuditState state)

  Local extension to standard callback that determines whether or not to process the file.

  Parameters:
    `filepath` - File pathname
    `state` - Audit handler state

### show

    public void show(RepInfo info)

  Outputs the information contained in a RepInfo object

  Specified by:

  Parameters:
    `info` - Object representation information
    `state` - Audit handler state

### showFooter

    public void showFooter()

  Do the final output. This should be in a suitable format for including multiple files between the header and the footer, and the XML of the header and footer must balance out.

  Specified by:
    `showFooter` in interface `OutputHandler`
  Overrides:
    `showFooter` in class `XmlHandler`

### showFooterImpl

    public void showFooterImpl(AuditState state)

### showHeaderImpl

    public AuditState showHeaderImpl(java.lang.String directory)

  Local extension to the standard callback that does the initial output. This should be in a suitable format for including multiple files between the header and the footer, and the XML of the header and footer must balance out.

  Parameters:
    `directory` - Current directory filepath

### startDirectory

    public void startDirectory(java.lang.String directory)

  Callback indicating a new directory is being processed. Additional state information can be added to the AuditState object in the showHeaderImpl() method before it is pushed onto the stack.
