Field Detail

### _content

    protected java.lang.StringBuffer _content

### _handlerParams

    protected java.util.List<java.util.List<java.lang.String>> _handlerParams

  The list of handler parameters. Each element in the List is a List of Strings (which may be empty but not null) representing parameters to be passed to the module. List elements are in one-to-one correspondence with _handler.

### _isHandler

    protected boolean _isHandler

### _isModule

    protected boolean _isModule

### _module

    protected java.util.List<ModuleInfo> _module

  The list of modules. Each element in the List is an array of two Strings representing the class and the initialization string.

### _modParams

    protected java.util.List<java.util.List<java.lang.String>> _modParams

  The list of module parameters. Each element in the List is a List of Strings (which may be empty but not null) representing parameters to be passed to the module. List elements are in one-to-one correspondence with _module.

Constructor Detail

### ConfigHandler

    public ConfigHandler()

  Creates a ConfigHandler.

Method Detail

### getModule

    public java.util.List<ModuleInfo> getModule()

  Returns the List of Modules specified by the config file. Each element of the List is a String[2] whose elements are the module class name and initialization value.

  See Also:
    `Module`

### getModuleParams

    public java.util.List<java.util.List<java.lang.String>> getModuleParams()

  Returns the List of module parameters specified by the config file. Each element of the List is a List (possibly empty) of Strings whose elements are parameters to pass to the module. The values returned by `getModuleParams()` are in one-to-one correspondence with those return by `getModule()`.

### getHandlerParams

    public java.util.List<java.util.List<java.lang.String>> getHandlerParams()

  Returns the List of handler parameters specified by the config file. Each element of the List is a List (possibly empty) of Strings whose elements are parameters to pass to the output handler. The values returned by `getHandlerParams()` are in one-to-one correspondence with those return by `getHandler()`.

### getHandler

    public java.util.List<java.lang.String[]> getHandler()

  Returns the List of OutputHandlers specified by the config file.

  See Also:
    `OutputHandler`

### getTempDir

    public java.lang.String getTempDir()

  Returns the temporary directory path specified by the config file, with final path separator.

### getMixVsn

    public java.lang.String getMixVsn()

  Returns the MIX schema version specified by the config file. Acceptable values are "0.2" and "1.0" and "2.0".

### getSigBytes

    public int getSigBytes()

  Returns the number of bytes to examine when looking for an indefinitely positioned signature, or checking the first sigBytes bytes of a file in lieu of a signature.

### getEncoding

    public java.lang.String getEncoding()

  Returns the character encoding specified by the config file.

### getBufferSize

    public int getBufferSize()

  Returns the buffer size specified in the config file.

  Returns:
    the buffer size, or -1 if none specified

### getExtensions

    public java.util.Map<java.lang.String,java.lang.String> getExtensions()

  Return an associative map of configuration extensions.

### getJhoveHome

    public java.lang.String getJhoveHome()

  Returns the path to the application's home directory, with final path separator.

### getLogLevel

    public java.lang.String getLogLevel()

  Returns the name of the desired log level. This should be the name of one of the predefined values of java.util.logging.Level, e.g., "WARNING", "INFO", "ALL". The default level is SEVERE.

### startElement

    public void startElement(java.lang.String namespaceURI,
                             java.lang.String localName,
                             java.lang.String rawName,

    `startElement` in interface `org.xml.sax.ContentHandler`
  Overrides:
    `startElement` in class `org.xml.sax.helpers.DefaultHandler`
  Throws:
    `org.xml.sax.SAXException`

### characters

    public void characters(char[] ch,
                           int start,
                           int length)
                    throws org.xml.sax.SAXException

  SAX parser callback method.

  Specified by:
    `characters` in interface `org.xml.sax.ContentHandler`
  Overrides:
    `characters` in class `org.xml.sax.helpers.DefaultHandler`
  Throws:
    `org.xml.sax.SAXException`

### endElement

    public void endElement(java.lang.String namespaceURI,
                           java.lang.String localName,
                           java.lang.String rawName)
                    throws org.xml.sax.SAXException

  SAX parser callback method.

  Specified by:
    `endElement` in interface `org.xml.sax.ContentHandler`
  Overrides:
    `endElement` in class `org.xml.sax.helpers.DefaultHandler`
  Throws:
    `org.xml.sax.SAXException`

### resolveEntity

    public org.xml.sax.InputSource resolveEntity(java.lang.String publicId,
                                                 java.lang.String systemId)
                                          throws org.xml.sax.SAXException,
                                                 java.io.IOException

  EntityResolver designed to locate the config schema. It tries to find it as a local resource. It appears that not all SAX implementations will actually call this function for schema resolution, so this isn't a guarantee that the schema in the config file won't be called directly. But hopefully it will cut down on the burden on the server with the official schema copy.

  Specified by:
    `resolveEntity` in interface `org.xml.sax.EntityResolver`
  Overrides:
    `resolveEntity` in class `org.xml.sax.helpers.DefaultHandler`
  Throws:
    `org.xml.sax.SAXException`
    `java.io.IOException`
