Interface PageElementFactory

All Known Implementing Classes:

PageElementFactoryImpl

public interface PageElementFactory

Used by the PageLoader to create partialar page elements. This has evolved and focused to mostly concern bindings and expansions.

Method Summary

Modifier and Type	Method	Description
RenderCommand	newAttributeElement(ComponentResources componentResources, AttributeToken token)	Creates a RenderCommand for rendering an attribute, when the attribute contains expansions.
Binding	newBinding(String parameterName, ComponentResources loadingComponentResources, ComponentResources embeddedComponentResources, String defaultBindingPrefix, String expression, Location location)	Creates a new binding as with BindingSource.newBinding(String, ComponentResources, ComponentResources, String, String, Location).
RenderCommand	newExpansionElement(ComponentResources componentResources, ExpansionToken token)	Converts an expansion token into a command that renders the expanded value.

Method Detail

newAttributeElement

RenderCommand newAttributeElement(ComponentResources componentResources,
                                  AttributeToken token)

Creates a RenderCommand for rendering an attribute, when the attribute contains expansions.

Parameters:

componentResources - identifies component

token - token containing value with expansions

Returns:

render command to render the text with expansions expanded

newExpansionElement

RenderCommand newExpansionElement(ComponentResources componentResources,
                                  ExpansionToken token)

Converts an expansion token into a command that renders the expanded value.

Parameters:

componentResources - identifies the component

token - contains expansion expression

Returns:

command to render expansion

newBinding

Binding newBinding(String parameterName,
                   ComponentResources loadingComponentResources,
                   ComponentResources embeddedComponentResources,
                   String defaultBindingPrefix,
                   String expression,
                   Location location)

Creates a new binding as with BindingSource.newBinding(String, ComponentResources, ComponentResources, String, String, Location). However, if the binding contains an expansion (i.e., ${...}), then a binding that returns the fully expanded expression will be returned.
