Class AbstractIncludeAssetWorker

java.lang.Object
  org.apache.tapestry.internal.transform.AbstractIncludeAssetWorker

All Implemented Interfaces:

ComponentClassTransformWorker

Direct Known Subclasses:

IncludeJavaScriptLibraryWorker, IncludeStylesheetWorker

public abstract class AbstractIncludeAssetWorker
extends Object
implements ComponentClassTransformWorker

Base class for workers that automatically inlcude assets in the page (via methods on PageRenderSupport).

Constructor Summary

AbstractIncludeAssetWorker(AssetSource assetSource, SymbolSource symbolSource)

Method Summary

protected void	addOperationForAssetPaths(ClassTransformation transformation, MutableComponentModel model, String[] assetPaths) Expands symbols in the path, then adds an operation into the setup render phase of the component.
protected abstract void	handleAsset(Asset asset) Invoked, from the component's setup render phase, for each asset.

Method Detail

addOperationForAssetPaths

protected final void addOperationForAssetPaths(ClassTransformation transformation,
                                               MutableComponentModel model,
                                               String[] assetPaths)

Expands symbols in the path, then adds an operation into the setup render phase of the component. Ultimately, handleAsset(org.apache.tapestry.Asset) will be invoked for each asset (dervied from assetPaths).

Parameters:

transformation - transformation process for component

model - component model for component

assetPaths - raw paths to be converted to assets

handleAsset

protected abstract void handleAsset(Asset asset)

Invoked, from the component's setup render phase, for each asset. This method must be threadsafe. Most implementation pass the asset to a particular method of PageRenderSupport.

Parameters:

asset - to be processed
