SimpleUrlReadingCondition

public interface UrlReadingCondition
extends com.atlassian.plugin.web.baseconditions.BaseCondition

Condition that contributes to the URL.

Web Resource module descriptors can use Conditions of this class or of Condition, however the use of Condition for webresources is discouraged. If a webresource contains a com.atlassian.plugin.web.Condition, that webresource is taken out of the batch and included as a standalone resource download. This has two negative effects:

• It breaks resource dependency, as the resource is no longer sent to the browser in dependency order
• It reduces performance, as the browser must initiate more connections to download resources that would otherwise be batched

UrlReadingConditions are included in batches. When an HTML page is served, the UrlReadingCondition is asked to contribute to the URL in addToUrl(com.atlassian.plugin.webresource.url.UrlBuilder). At resource serve time, the condition evaluates whether it should display based on the querystring.

Since:

v3.0
