Constructor Detail

ResourceAwareMacroDecorator

public ResourceAwareMacroDecorator(Macro macro)

Method Detail

getResourcePath

public java.lang.String getResourcePath()

Specified by:

getResourcePath in interface ResourceAware

setResourcePath

public void setResourcePath(java.lang.String resourcePath)

Specified by:

setResourcePath in interface ResourceAware

getTokenType

public TokenType getTokenType(java.util.Map parameters,
                              java.lang.String body,
                              RenderContext context)

Description copied from interface: Macro

Declares what sort of html elements are returned by the macro. TokenType.INLINE elements will have paragraphs drawn around them, or be incorporated into paragraphs they are included in. TokenType.BLOCK elements will be treated as their own paragraph, splitting any paragraphs they would otherwise be in. TokenType.INLINE_BLOCK elements will not have paragraphs drawn around them, but they won't split any paragraphs they appear in either.

Macros that contain elements that shouldn't appear in a paragraph, such as pre, should return TokenType.BLOCK. If it produces a span, replacement text or text decoration, return TokenType.INLINE. If it affects logic of whether its children are displayed but doesn't add its own content, or you aren't sure what to return, return TokenType.INLINE_BLOCK.

Specified by:

getTokenType in interface Macro

Parameters:

parameters - the parameters passed to the macro. These are useful here for macros that take parameters which dramatically alter the appearance of the macro.

body - the macro body is provided in case its content could have a bearing on the type of element returned by the macro

context - the context is provided in case its content could have a bearing on the type of element returned by the macro

Returns:

the TokenType that matches the content produced by this macro

isInline

public boolean isInline()

Description copied from interface: Macro

Determine if the macro is an "inline" element in the resulting HTML. Inline elements will have paragraphs drawn around them, or be incorporated into paragraphs they are included in. As a rule of thumb, if your macro produces a paragraph, table or div (or so on), you should return false. If it produces a span, replacement text or text decoration, return true.

Most macros will want to return false here.

Specified by:

isInline in interface Macro

Returns:

true if the macro output is included inline within the surrounding HTML, false if it forms its own HTML block.

hasBody

public boolean hasBody()

Description copied from interface: Macro

Determine if the macro is a one-shot macro, or one that takes a body. If this method returns false, the renderer will NOT look for an end-tag for the macro. If the method returns true, the renderer will look for an end-tag, but if the end-tag is not found then the macro will be processed with an empty body.

Specified by:

hasBody in interface Macro

getBodyRenderMode

public RenderMode getBodyRenderMode()

Description copied from interface: Macro

If the macro has a body, return the mode in which the body of the macro should be rendered. The body of the macro will be rendered before the macro is executed!

If this method returns null, it causes the macro processor to treat the macro as one that returns wiki-text rather than HTML. The body of the macro will be passed in un-rendered, and the macro's output will be inserted back into the page for further normal processing by the wiki-engine.

Specified by:

getBodyRenderMode in interface Macro

Returns:

the RenderMode in which the body of this macro should be rendered, or null if the macro is substituting wiki-text

execute

public java.lang.String execute(java.util.Map parameters,
                                java.lang.String body,
                                RenderContext renderContext)
                         throws MacroException

Description copied from interface: Macro

Execute the macro. Macros should write any output to the writer (it will be rendered in the RenderMode returned in Macro.getBodyRenderMode()).

Macros are expected to output HTML. The output of macros will not be subjected to any further processing by the wiki-engine. If your macro produces wiki-text, you are responsible for rendering that text to HTML yourself using a SubRenderer or WikiStyleRenderer. If your macro returns pure wiki-text, you can force further processing in the normal chain by returning null from Macro.getBodyRenderMode()

Specified by:

execute in interface Macro

Parameters:

parameters - the parameters included in the macro

body - the content of the body of the macro

renderContext - the rendering context in which the macro was executed

Returns:

the output of the macro

Throws:

MacroException - if the macro fails in some unremarkable way. If the macro fails in a way that is important to the server maintainer (i.e. something is badly wrong), throw a RuntimeException instead.

getMacro

public Macro getMacro()

suppressSurroundingTagDuringWysiwygRendering

public boolean suppressSurroundingTagDuringWysiwygRendering()

Description copied from interface: Macro

Suppress surrounding div/span during Wysiwyg rendering. This should return true if the macro provides it's own Wysiwyg processing HTML.

Specified by:

suppressSurroundingTagDuringWysiwygRendering in interface Macro

suppressMacroRenderingDuringWysiwyg

public boolean suppressMacroRenderingDuringWysiwyg()

Description copied from interface: Macro

Suppress the rendering of the macro -- the macro's body may still be rendered (depending on the render mode of the macro), but the HTML the macro adds will not be created.

Specified by:

suppressMacroRenderingDuringWysiwyg in interface Macro

Returns:

getWysiwygBodyType

public WysiwygBodyType getWysiwygBodyType()

Description copied from interface: Macro

Defines how the Macro's body should be rendered for Wysiwyg editors. This method is only relevant for macros that return false from Macro.suppressSurroundingTagDuringWysiwygRendering(), true from Macro.suppressMacroRenderingDuringWysiwyg() and true from Macro.hasBody().

Specified by:

getWysiwygBodyType in interface Macro

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
