public WroManager()

Method Detail

process

public final void process()
                   throws IOException

Perform processing of the uri.

Parameters:

request - HttpServletRequest to process.

response - HttpServletResponse where to write the result content.

Throws:

IOException - when any IO related problem occurs or if the request cannot be processed.

encodeVersionIntoGroupPath

public final String encodeVersionIntoGroupPath(String groupName,
                                               ResourceType resourceType,
                                               boolean minimize)

Encodes a fingerprint of the resource into the path. The result may look like this: ${fingerprint}/myGroup.js

Returns:

a path to the resource with the fingerprint encoded as a folder name.

formatVersionedResource

protected String formatVersionedResource(String hash,
                                         String resourcePath)

Format the version of the resource in the path. Default implementation use hash as a folder: /groupName.js. The implementation can be changed to follow a different versioning style, like version parameter: /groupName.js?version=

Parameters:

hash - Hash of the resource.

resourcePath - Path of the resource.

Returns:

formatted versioned path of the resource.
