Creates a dynamic resource

Parameters:

locale - The locale of this resource

cacheTimeout - The cache duration timeout

Method Detail

getResourceStream

public final IResourceStream getResourceStream()

Deprecated.

Description copied from class: Resource

Returns a new IResourceStream that provides all data for the request. Despite its name, this method should return a new IResourceStream instance each time it is invoked (otherwise the InputStream returned from the IResourceStream would be at EOF when a second request is handled for the same Resource). The caller must invoke IResourceStream.close() when finished.

Specified by:

getResourceStream in class Resource

Returns:

Gets the image resource to attach to the component.

invalidate

public void invalidate()

Deprecated.

Description copied from class: Resource

Sets any loaded resource to null, thus forcing a reload on the next request.

Overrides:

invalidate in class Resource

See Also:

Resource.invalidate()

getResourceState

protected abstract DynamicByteArrayResource.ResourceState getResourceState()

Deprecated.

Gets the byte array for our dynamic resource. If the subclass regenerates the data, it should set the lastModifiedTime too. This ensures that image caching works correctly.

Returns:

The byte array for this dynamic resource.
