createCompressedFileVersion

protected void createCompressedFileVersion(javax.faces.context.FacesContext facesContext,
                                           ResourceMeta resourceMeta,
                                           File target)

Uses GZIPOutputStream to compress this resource. It will be stored where getCompressedFile() points to. Note that the resource really must be compressable (isCompressable() must return true).

getWrapped

public ResourceLoader getWrapped()
