ro.isdc.wro.config
Interface ReadOnlyContext

All Known Implementing Classes:

Context

public interface ReadOnlyContext

A readonly version of Context. Prefer to use fields of this type for injection in processors, because it is thread-safe (the getAggregatedFolderPath is computed correctly in multi-threaded environment).

The interface is required to make it possible to create Proxy of the Context during injection using standard jdk support. It is possible to create also proxies for classes, but a new dependency is required for this (javassist), which is something I prefer to avoid at this point.

getAggregatedFolderPath

String getAggregatedFolderPath()

This field is useful only for the aggregated resources of type ResourceType.CSS.
The aggregatedFolderPath is used to compute the depth. For example, if aggregatedFolder is "wro" then the depth is 1 and the path used to prefix the image url is "..". If the aggregatedFolder is "css/aggregated", the depth is 2 and the prefix is "../..". The name of the aggregated folder is not important, it is used only to compute the depth.

Returns:

the aggregatedFolderPath
