public final class DynamicHierPattern
extends BasePattern<DynamicHierOptions>

Pattern responsible for building the switcher subtree of a dynamic hierarchy component. The DynamicHierarchyIteratorPattern delegates to this pattern to create the switcher containing a GROUP and ATTRIBUTE facet. This pattern supports creation and rebinding. It can be used with a widget's bind method, and can generate the options given a root subtree to bind. A switcher is generated with default values for attribute values. You can optionally specify alternative values for selected attributes by calling the set methods in the options class.

Method Summary

Modifier and Type	Method and Description
BinderResult	bind(BinderParams<DynamicHierOptions> params) Binds the dynamic heirarchy component widget.
boolean	canRebind(org.w3c.dom.Node parent, org.w3c.dom.Node toBind) By default, Binders have the option of checking the DOM tree further to see if they can be bound to it.
CreatorResult	create(CreatorParams<DynamicHierOptions> params) Creates the dynamic hierarchy Component, defers to bind for binding the attributes.
DynamicHierOptions	createOptions(CreatorParams<DynamicHierOptions> params) Returns a new options class where all attributes are initially null.
DynamicHierOptions	generateOptions(BinderParams<DynamicHierOptions> params) Generates an options class based on the bind root.

DynamicHierPattern

public DynamicHierPattern()

Method Detail

create

public CreatorResult create(CreatorParams<DynamicHierOptions> params)

Creates the dynamic hierarchy Component, defers to bind for binding the attributes.

Specified by:

create in interface Creator2<DynamicHierOptions>

Specified by:

create in class BasePattern<DynamicHierOptions>

Parameters:

params - See CreatorParams for listing

Returns:

creator result

bind

public BinderResult bind(BinderParams<DynamicHierOptions> params)

Binds the dynamic heirarchy component widget.

Specified by:

bind in interface Binder2<DynamicHierOptions>

Specified by:

bind in class BaseBinder2<DynamicHierOptions>

Parameters:

params - See BinderParams for a complete list

Returns:

Typically just one of the convenience classes in BinderResult

createOptions

public DynamicHierOptions createOptions(CreatorParams<DynamicHierOptions> params)

Returns a new options class where all attributes are initially null.

Specified by:

createOptions in interface Creator2<DynamicHierOptions>

Overrides:

createOptions in class BasePattern<DynamicHierOptions>

Parameters:

params - See CreatorParams for a complete list

Returns:

An instance of PatternOptions with the current options set, or null if not supported

generateOptions

public DynamicHierOptions generateOptions(BinderParams<DynamicHierOptions> params)

Generates an options class based on the bind root.

Specified by:

generateOptions in interface Binder2<DynamicHierOptions>

Overrides:

generateOptions in class BaseBinder2<DynamicHierOptions>

Parameters:

params - See BinderParams for a complete list

Returns:

An instance of PatternOptions with the current options set, or null if not supported

canRebind

public boolean canRebind(org.w3c.dom.Node parent,
                         org.w3c.dom.Node toBind)

Description copied from class: BaseBinder2

By default, Binders have the option of checking the DOM tree further to see if they can be bound to it. However, the framework will first already check the node signature of the defined pattern, and for many cases, this is sufficient. Subclasses that do override this should be sure to also override the annotation on the class, such that: @SimpleRebindChecking(true)

Specified by:

canRebind in interface Binder2<DynamicHierOptions>

Overrides:

canRebind in class BaseBinder2<DynamicHierOptions>

Parameters:

parent - The parent of the nodes to be bound

toBind - The nodes to bind. Typically either a DocumentFragment or Element

Returns:

boolean true or false if binder knoows how to bind the node
