Method Detail

proxyIComponent

public static <T extends org.zkoss.zk.ui.Component,I extends IComponent> I proxyIComponent(T t)

Makes a proxy of Component into IComponent.

Parameters:

t - a ZK Component

Returns:

a proxy of IComponent

proxyIChildren

public static java.util.List<? extends IComponent> proxyIChildren(org.zkoss.zk.ui.Component instance)

proxyIChild

public static IComponent proxyIChild(org.zkoss.zk.ui.Component instance)

proxyIChild

public static IComponent proxyIChild(org.zkoss.zk.ui.Component instance,
                                     java.lang.Class<? extends org.zkoss.zk.ui.Component> skipClass)

createComponents

public static <T extends IComponent> java.util.List<T> createComponents(org.zkoss.zk.ui.metainfo.PageDefinition pagedef,
                                                                        java.util.Map<?,?> arg)

Creates IComponents from Components that don't belong to any page from the specified page definition.

Parameters:

pagedef - the page definition to use. It cannot be null.

arg - a map of parameters that is accessible by the arg variable in EL, or by Execution.getArg(). Ignored if null.

Returns:

the first component being created.

Since:

2.4.0

createComponents

public static <T extends IComponent> java.util.List<T> createComponents(java.lang.String uri,
                                                                        java.util.Map<?,?> arg)

Creates IComponents from Components that don't belong to any page from a page file specified by an URI.

It loads the page definition from the specified URI (by use Execution.getPageDefinition(java.lang.String) ), and then invokes createComponents(PageDefinition,Map) to create components.

Parameters:

arg - a map of parameters that is accessible by the arg variable in EL, or by Execution.getArg(). Ignored if null.

createComponents(PageDefinition, Map)

createComponentsDirectly

public static <T extends IComponent> java.util.List<T> createComponentsDirectly(java.lang.String content,
                                                                                java.lang.String extension,
                                                                                java.util.Map<?,?> arg)

Creates IComponents from Components that don't belong to any page from the raw content specified by a string.

The raw content is parsed to a page definition by use of Execution.getPageDefinitionDirectly(String, String), and then invokes createComponents(PageDefinition,Map) to create components.

Parameters:

content - the raw content of the page. It must be in ZUML.

extension - the default extension if the content doesn't specify an language. In other words, if the content doesn't specify an language, LanguageDefinition.getByExtension(java.lang.String) is called. If extension is null and the content doesn't specify a language, the language called "xul/html" is assumed.

arg - a map of parameters that is accessible by the arg variable in EL, or by Execution.getArg(). Ignored if null.

newReplacer

public static <T extends IComponent> IReplacer<T> newReplacer(T root)

Constructs a replacer for replacing the descendant of the IComponent tree in a bulk execution for multiple replacements. By default, the implementation uses BFS algorithm to traverse the whole tree to seek the replacement target.

Parameters:

root - The root IComponent tree.

Returns:

A replacer implementation of IReplacer

replaceDescendant

public static <R extends IComponent,T extends IComponent> R replaceDescendant(R root,
                                                                                    T source,
                                                                                    T target)

Replaces the descendant of the given root with the new child from the given source, if any.

Parameters:

root - The root IComponent tree.

source - The replaced source.

target - The replaced target.

Returns:

The new IComponent tree.

replaceDescendantById

public static <R extends IComponent> R replaceDescendantById(R root,
                                                             java.lang.String sourceId,
                                                             IComponent<?> target)

Replaces the descendant of the given root with the new child from the given source, if any.

Parameters:

root - The root IComponent tree.

sourceId - The id of the replaced source.

target - The replaced target.

Returns:

The new IComponent tree.

replaceDescendantById

public static <R extends IComponent,T extends IComponent> R replaceDescendantById(R root,
                                                                                        java.lang.String sourceId,
                                                                                        CheckedFunction<T,T> targetFunction)

Replaces the descendant of the given root with the new child from the given source, if any.

Parameters:

root - The root IComponent tree.

sourceId - The id of the replaced source.

targetFunction - The replacement function by passing the result of the source and returning the new replacement. If null, it means to remove the replaced source.

Returns:

The new IComponent tree.
