WebResourceManager

com.atlassian.plugin.webresource.WebResourceManager
Known Indirect Subclasses

Class Overview

Manage 'css', 'javascript' and other 'resources' that are usually linked at the top of pages using <script> and <link> tags.

By using the WebResourceManager, components can declare dependencies on javascript and css that they would otherwise have to embed inline (which means that it can't be cached, and are often duplicated in a page).

Public Methods

public T executeInNewContext (Supplier<T> nestedExecution)

Executes a Supplier within a new WebResourceManager context. The request-local state manipulated by requireResource and requireResourcesForContext is preserved, an empty state is initialized for the execution of nestedExecution and after the nestedExecution is run, the old state is restored. If no return is required from the nestedExecution then Suppier can be used. Useful for rendering of pages which include nested pages (such as gadgets), which need to resolve the requirements of the inner pages without polluting the outer page's resources.

Parameters
nestedExecution the code to be executed in the empty context.
Returns
  • the value returned by nestedExection.get()

public String getRequiredResources (UrlMode urlMode)

This is the equivalent of calling getRequiredResources(UrlMode, WebResourceFilter) with the given url mode and a default filter that is dependent on the implementation.

Returns
  • the resource tags for all resources previously required
See Also

@Deprecated public String getRequiredResources ()

This method is deprecated.
As of 2.3.0, replaced by getRequiredResources(UrlMode)

public String getRequiredResources (UrlMode urlMode, WebResourceFilter webResourceFilter)

Returns the resource tags for the previously required resources called via requireResource(String) that match the specified web resource filter. If you are outputting the value to a Writer, use includeResources(Writer, UrlMode).

Example - if a 'javascript' resource has been required earlier with requireResource() and this method is called with JavascriptWebResource.FILTER_INSTANCE, it should return: 
  <script type="text/javascript" src="$contextPath/scripts/javascript.js"></script>
Similarly for other supported resources.

This method formats resource URLs in either relative or absolute format, depending on the value of urlMode. See UrlMode for details of the different options for URL format.

Parameters
urlMode specifies whether to use absolute URLs, relative URLs, or allow the concrete implementation to decide
webResourceFilter the web resource filter to filter resources on
Returns
  • the resource tags for all resources previously required
See Also

public String getResourceTags (String moduleCompleteKey, UrlMode urlMode)

Returns the resource tags of the specified resource. If you are outputting the value to a Writer, use requireResource(String, java.io.Writer, UrlMode).

This method formats resource URLs in either relative or absolute format, depending on the value of urlMode. See UrlMode for details of the different options for URL format.
Parameters
moduleCompleteKey The fully qualified plugin web resource module (eg jira.webresources:scriptaculous)
urlMode specifies whether to use absolute URLs, relative URLs, or allow the concrete implementation to decide
Returns
  • the resource tags for the specified resource
See Also

@Deprecated public String getResourceTags (String moduleCompleteKey)

This method is deprecated.
As of 2.3.0, replaced by getResourceTags(String, UrlMode)

@Deprecated public String getStaticPluginResource (ModuleDescriptor<?> moduleDescriptor, String resourceName, UrlMode urlMode)

This method is deprecated.
As of 2.9.0, replaced by getStaticPluginResourceUrl(com.atlassian.plugin.ModuleDescriptor, String, UrlMode)

A helper method to return a url for 'plugin' resources. Generally the implementation will return

/s/{build num/{system counter}/{plugin version}/_/download/resources/plugin.key:module.key/resource.name}

Note that the servlet context is prepended, and there is no trailing slash.

Typical usage is to replace:

<%= request.getContextPath() %>/download/resources/plugin.key:module.key/resource.name with <%= webResourceManager.getStaticPluginResource(descriptor, resourceName) %>

This method returns a URL in either a relative or an absolute format, depending on the value of urlMode. See UrlMode for details of the different options for URL format.
Parameters
moduleDescriptor plugin module descriptor that contains the resource
resourceName the name of the resource as defined in the plugin manifest
urlMode specifies whether to use absolute URLs, relative URLs, or allow the concrete implementation to decide
Returns
  • returns the url of this plugin resource
