showLanguageHelp

public abstract void showLanguageHelp(Context context,
                    java.lang.String symbolName)

Shows help on the language symbol symbolName

Parameters:

context - The current context to use for resolving the symbolName

symbolName - the language token used for help

registerHelpSetURL

public abstract void registerHelpSetURL(java.net.URL url)

Registers the URL to a HelpSet file. This is typically an absolute JAR URL (ie, jar:file:C:/jdev/lib/ext/helpset.jar!/helpset.hs) or a relative URL on the CLASSPATH (ie URL u = getClass().getResource("/helpset.hs"); )

registerHelpSetURL

public abstract void registerHelpSetURL(java.net.URL url,
                      java.lang.String relativeToName,
                      int relativeLocation)

Registers the { @link URL} to a HelpSet file. This is typically an absolute JAR URL (ie, jar:file:C:/jdev/lib/ext/helpset.jar!/helpset.hs) or a relative URL on the CLASSPATH (ie URL u = getClass().getResource("/helpset.hs"); ) This method is used to position the given HelpSet file before or after a HelpSet file already in the list of help sets. If the specified help set name cannot be found it will simply be added at the end of the list.

Parameters:

url - The URL of the HelpSet file to add to the help system

relativeToName - The file name to use for relative placement of this HelpSet file. Only use the file name, eg, getting_started.jar)

relativeLocation - Use the values HelpSystem.ADD_BEFORE or HelpSystem.ADD_AFTER to indicate how this HelpSet file should be place relative to the given relativeToName

registerHelpSetURL

public void registerHelpSetURL(java.lang.String name,
                      int helpAction,
                      java.net.URL controlFileURL,

                      int relativeLocation)

Registers the URL to a HelpSet jar file that contains all the control files necessary for OHJ.

Parameters:

name - unique key used to identify the help jar

helpAction - ADD_UPDATE_ACTION or REMOVE_ACTION

controlFileURL - the url to use for creating the HelpSet

relativeName - key used to identify a help jar this help jar should appear relative to

relativeLocation - ADD_BEFORE or ADD_AFTER; value is meaningless when relativeName is null

registerHelpSetURL

public abstract void registerHelpSetURL(java.lang.String name,
                      int helpAction,
