Class RenderedContentStore

java.lang.Object

com.atlassian.renderer.RenderedContentStore

public class RenderedContentStore
extends Object

Hides content from the renderer so that it will not be processed any further.

The RenderedContentStore associates blocks of rendered content (or Renderable objects that can later be transformed into rendered content) with tokens. These tokens can then be substituted for the content blocks during the rendering process. At the end of the chain of renderers, all tokens are replaced once more with their associated content blocks.

Using this technique, it is possible to 'hide' content from the renderer, making it unnecessary to perform nasty hacks to prevent the output of macros or renderer components from being broken by subsequent rendering steps.

Method Detail

getFromRenderContext

public static RenderedContentStore getFromRenderContext(RenderContext renderContext)

Retrieve the store from the render context. If the store is not in the context, it is created.

Parameters:

renderContext - the render context to retrieve the store from

Returns:

the active store for this context

addContent

public String addContent(Object content,
                         TokenType type)

Add content to the store. Returns a token that can be placed in the page to be looked up later.

Parameters:

content - the content to add to the store

type - whether the content is TokenType.INLINE or TokenType.BLOCK. The token returned will reflect this type.

Returns:

a token that the ContentReplaceFilter will be able to use to locate the content at a later date.

addBlock

public String addBlock(Object content)

Put some content block into the store. Returns a token that can be placed in the page to be looked up later. The renderer knows not to draw things like paragraphs around another block.

Parameters:

content - the content to add to the store

Returns:

a token that the ContentReplaceFilter will be able to use to locate the content at a later date.

addInline

public String addInline(Object content)

Put some inline content into the store. Returns a token that can be placed in the page to be looked up later. Inline elements will be surrounded by paragraphs and have newlines inserted between them as necessary.

Parameters:

content - the content to add to the store

Returns:

a token that the ContentReplaceFilter will be able to use to locate the content at a later date.

get

public Object get(String token)

Get some content back, given the entire token that was returned from a previous 'add'

Parameters:

token - a token that was returned from a previous add

Returns:

the appropriate content, or null if the content could not be found for that token.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

stripTokens

public static String stripTokens(String text)
