Class WroManager

java.lang.Object

ro.isdc.wro.manager.WroManager

All Implemented Interfaces:

WroConfigurationChangeListener

public class WroManager
extends Object
implements WroConfigurationChangeListener

Contains all the factories used by optimizer in order to perform the logic. This object should be created through WroManagerFactory, in order to ensure that all dependencies are injected properly. In other words, avoid setting the fields explicitly after creating a new instance of WroManager.

Most of the fields of this class are annotated with @Inject, in order to ensure that each instance can benefit use @Inject annotation on its fields.

Method Detail

process

public final void process()
                   throws IOException

Perform processing of the uri.

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.

onCachePeriodChanged

Parameters:

period - number of seconds used by scheduler to trigger cache change.

onModelPeriodChanged

public final void onModelPeriodChanged(long period)

Description copied from interface: WroConfigurationChangeListener

Invoked when the modelPeriod property is changed.

Specified by:

onModelPeriodChanged in interface WroConfigurationChangeListener

Parameters:

period - number of seconds used by scheduler to trigger model change.
