Interface IStripeStyleRenderer

All Known Implementing Classes:

TemplateStripeStyleRenderer, VoidStripeStyleRenderer

public interface IStripeStyleRenderer

Interface used by IStripeStyle implementations that can be used to query the actual IVisualCreator implementation for a stripe and an associated style.

Implementations of this interface should be designed to be sharable between multiple style instances and should therefore not contain style specific state.

IStripeStyle, IStripe

Method Summary

Modifier and Type	Method and Description
ILookup	getContext(IStripe stripe, IStripeStyle style) Gets a temporary context instance that can be used to query additional information for the stripe's style.
IVisualCreator	getVisualCreator(IStripe stripe, IStripeStyle style) Gets an implementation of the IVisualCreator interface that can handle the provided stripe and its associated style.

Method Detail

getContext

ILookup getContext(IStripe stripe,
                   IStripeStyle style)

Gets a temporary context instance that can be used to query additional information for the stripe's style.

Implementations may return ILookup.EMPTY if they don't support this, but may not return null.

Parameters:

stripe - The stripe to provide a context instance for.

style - The style to use for the context.

Returns:

An non-null lookup implementation.

ILookup.EMPTY, ILookup

getVisualCreator

IVisualCreator getVisualCreator(IStripe stripe,
                                IStripeStyle style)

Gets an implementation of the IVisualCreator interface that can handle the provided stripe and its associated style.

This method may return a flyweight implementation, but never null.

Parameters:

stripe - The nstripeode to provide an instance for

style - The style to use for the creation of the visual

Returns:

An implementation that may be used to subsequently create or update the visual for the stripe. Clients should not cache this instance and must always call this method immediately before using the value returned. This enables the use of the flyweight design pattern for implementations. This method may not return null but should yield a void implementation instead.
