Method Detail

getName

public java.lang.String getName()

Description copied from class: AbstractWandoraTool

Tools name represent the tool in UI unless the tool has been given explicitly another GUI name. All tools should override this method and return a valid string representing name of the tool.

Specified by:

getName in interface WandoraTool

Overrides:

getName in class AbstractExtractor

Returns:

String representing tool's name.

getDescription

public java.lang.String getDescription()

Description copied from class: AbstractWandoraTool

AdminToolManager views tool descriptions while user browses available tools and build user customizable GUI elements such as Tools menu. By default description equals the tool name. All tools should override this method.

Specified by:

getDescription in interface WandoraTool

Overrides:

getDescription in class AbstractExtractor

Returns:

String representing tool's description.

getIcon

public javax.swing.Icon getIcon()

Description copied from class: AbstractWandoraTool

All tools may have identifying graphic icon used within tool GUI elements. getIcon should return Icon object of the tool.

Specified by:

getIcon in interface WandoraTool

Overrides:

getIcon in class AbstractExtractor

Returns:

icon for the tool.

getType

public WandoraToolType getType()

Description copied from class: AbstractWandoraTool

Tool type is used to categorize tools. Tool type has no real effect today, it is merely an informative property of a tool.

Specified by:

getType in interface WandoraTool

Overrides:

getType in class AbstractExtractor

Returns:

Tool's type object.

getContentTypes

public java.lang.String[] getContentTypes()

Description copied from interface: Handler

Returns an array of String containing the content-types this ContentHandler can process.

Specified by:

getContentTypes in interface Handler

Overrides:

getContentTypes in class AbstractExtractor

Returns:

String array representing content types.

useURLCrawler

public boolean useURLCrawler()

Overrides:

useURLCrawler in class AbstractExtractor

isConfigurable

public boolean isConfigurable()

Description copied from class: AbstractWandoraTool

Whether this tool is configurable. Configurable tools will provide an interface to configure themselves. To make a configurable tool you will need to:

• Implement isConfigurable method and return true there.
• Implement initialize method to initialize the tool with saved options.
• Implement configure method to provide the user interface for configuration and then save the new options.
• Implement writeOptions method to save the current options.

Specified by:

isConfigurable in interface WandoraTool

Overrides:

isConfigurable in class AbstractWandoraTool

Returns:

true if the tool is configurable.
