updateMacroDefinitions

public String updateMacroDefinitions(String storageFragment,
                                     ConversionContext context,
                                     MacroDefinitionUpdater updater)
                              throws XhtmlException

Description copied from interface: MacroDefinitionTransformer

Updates MacroDefinitions in the supplied storageFragment.

 // Changes the name of all "mice" macros to "cheese".
 page.setBodyAsString(xhtmlContent.updateMacroDefinitions(page.getBodyAsString(), context, new XhtmlContent.MacroDefinitionUpdater()
    {
        public MacroDefinition update(MacroDefinition macroDefinition)
        {
            if ("mice".equals(macroDefinition.getName()))
                macroDefinition.setName("cheese");

            return macroDefinition;
        }
    }));
 

Specified by:

updateMacroDefinitions in interface MacroDefinitionTransformer

Parameters:

storageFragment - or more typically the storage representation of a complete ContentEntityObject which might contain macro definitions.

context - for the conversion.

updater - which is called to update each MacroDefinition found.

Returns:

the storage representation of the modified fragment.

Throws:

XhtmlException - if there was a problem reading the storage fragment, creating the MacroDefinition or creating the modified fragment.

replaceMacroDefinitionsWithString

public String replaceMacroDefinitionsWithString(String storageFragment,
                                                ConversionContext context,
                                                MacroDefinitionReplacer replacer)
                                         throws XhtmlException

Description copied from interface: MacroDefinitionTransformer

Replaces MacroDefinitions in the supplied storageFragment with a String. Use {link #updateMacroDefinitions} rather than this method if you wish to replace or update one definition with another.

 // Replaces "cheese" macros with some XHTML.
 page.setBodyAsString(xhtmlContent.replaceMacroDefinitionsWithString(page.getBodyAsString(), context, new MacroDefinitionReplacer()
    {
        public String replace(MacroDefinition macroDefinition) throws XhtmlException
        {
            if ("cheese".equals(macroDefinition.getName()))
                return "
I hate cheese!
";

            return xhtmlContent.convertMacroDefinitionToStorage(macroDefinition, context);
        }
    }));
 

Specified by:

replaceMacroDefinitionsWithString in interface MacroDefinitionTransformer

Parameters:

storageFragment - or more typically the storage representation of a complete ContentEntityObject which might contain macro definitions.

context - for the conversion.

replacer - which is called to replace each MacroDefinition found with a replacement in storage format (typically XHTML).

Returns:

the storage representation of the modified fragment.

Throws:

XhtmlException - if there was a problem reading the storage fragment, creating the MacroDefinition or creating the modified fragment.

handleMacroDefinitions

public void handleMacroDefinitions(String storageFragment,

                            throws XhtmlException

Description copied from interface: MacroDefinitionTransformer

Perform an operation on MacroDefinitions in the supplied storageFragment without making changes to the storage representation.

    });
 MacroDefinition lastMacro = atomicMacroDefinition.get();
 

Specified by:

handleMacroDefinitions in interface MacroDefinitionTransformer

Parameters:

storageFragment - or more typically the storage representation of a complete ContentEntityObject which might contain macro definitions.

context - for the conversion.

handler - which is called each MacroDefinition found.

Throws:

XhtmlException - if there was a problem reading the storage fragment or creating the MacroDefinition.

handleMacroDefinitions

public void handleMacroDefinitions(String storageFragment,
                                   ConversionContext context,
