Interface JiraRendererPlugin

All Known Implementing Classes:

AtlassianWikiRenderer, DefaultTextRenderer

public interface JiraRendererPlugin

The top-level interface that defines a renderer and its configuration within jira.

Method Summary

JiraRendererModuleDescriptor	getDescriptor() Simple accessor method for the module descriptor.
String	getRendererType() Returns a unique identifier for this renderer plugin.
void	init(JiraRendererModuleDescriptor jiraRendererModuleDescriptor) This allows a plugin to get a handle on the module descriptor that spawned the plugin.
String	render(String value, IssueRenderContext context) This will render the provided value within the provided context and produce a rendered output.
String	renderAsText(String value, IssueRenderContext context) This will render the provided value within the provided context and produce a rendered output that is text readable.
Object	transformForEdit(Object rawValue) This allows the renderer to perform a transformation on the raw value before populating an editable component with the value.
Object	transformFromEdit(Object editValue) This allows the renderer to perform a transformation on the submitted edit value before storing the value in the system.

Method Detail

render

public String render(String value,
                     IssueRenderContext context)

This will render the provided value within the provided context and produce a rendered output.

Parameters:

value - the raw value to render.

context - the issue context for this rendering

Returns:

the transformed value having passed through the rendering process.

renderAsText

public String renderAsText(String value,
                           IssueRenderContext context)

This will render the provided value within the provided context and produce a rendered output that is text readable.

Parameters:

value - the raw value to render.

context - the issue context for this rendering

Returns:

the transformed value having passed through the rendering process, the value must be text readable.

getRendererType

public String getRendererType()

Returns a unique identifier for this renderer plugin.

Returns:

the unique identifier for this renderer plugin implmentation.

transformForEdit

public Object transformForEdit(Object rawValue)

This allows the renderer to perform a transformation on the raw value before populating an editable component with the value. This can be useful if the value being stored is a different format (i.e. wiki markup), than the edit component expects (i.e. wysiwig edit control that expects html). NOTE: this method need not do anything if the edit control can handle the value as stored in the system.

Parameters:

rawValue - is the value stored in the system, before transform.

Returns:

the value in a form that the renderers edit control expects.

transformFromEdit

public Object transformFromEdit(Object editValue)

This allows the renderer to perform a transformation on the submitted edit value before storing the value in the system. This can be useful if the value being submitted is a different format (i.e. html markup that the edit control generates), than the system expects to store (i.e. wiki markup). NOTE: this method need not do anything if the system is happy to store the value the edit control produces.

Parameters:

editValue - is the value produced by the edit control.

Returns:

the value in a form that the system expects to store.

init

public void init(JiraRendererModuleDescriptor jiraRendererModuleDescriptor)

This allows a plugin to get a handle on the module descriptor that spawned the plugin.

Parameters:

jiraRendererModuleDescriptor - is the module descriptor that spawned the plugin. If the plugin uses resources, such as velocity templates, then access can be gained through this descriptor.

getDescriptor

public JiraRendererModuleDescriptor getDescriptor()

Simple accessor method for the module descriptor.

Returns:

the module descriptor that spawned this renderer.
