Method Detail

addAsset

public void addAsset(java.lang.String name,
                     IAsset asset)
Description copied from interface: IComponent
Adds an asset to the component. This is invoked from the page loader.

Specified by:
addAsset in interface IComponent

addComponent

public void addComponent(IComponent component)
Description copied from interface: IComponent
Adds a component to a container. Should only be called during the page loading process, which is responsible for any checking.

Specified by:
addComponent in interface IComponent

addBody

public void addBody(IRender element)
Adds an element (which may be static text or a component) as a body element of this component. Such elements are rendered by renderBody(IMarkupWriter, IRequestCycle) 55 .

Specified by:
addBody in interface IComponent
Since:
2.2

finishLoad

public void finishLoad(IRequestCycle cycle,
                       org.apache.tapestry.engine.IPageLoader loader,
                       org.apache.tapestry.spec.IComponentSpecification specification)
Registers this component as a listener of the page if it implements org.apache.tapestry.event.PageDetachListeneror org.apache.tapestry.event.PageRenderListener.

Invokes finishLoad() 55 . Subclasses may overide as needed, but must invoke this implementation. BaseComponentloads its HTML template.

Specified by:
finishLoad in interface IComponent

renderInformalParameters

protected void renderInformalParameters(IMarkupWriter writer,
                                        IRequestCycle cycle)
Converts informal parameters into additional attributes on the curently open tag.

Invoked from subclasses to allow additional attributes to be specified within a tag (this works best when there is a one-to-one corespondence between an IComponentand a HTML element.

Iterates through the bindings for this component. Filters out bindings when the name matches a formal parameter (as of 1.0.5, informal bindings are weeded out at page load / template load time, if they match a formal parameter, or a specificied reserved name). For the most part, all the bindings here are either informal parameter, or formal parameter without a corresponding JavaBeans property.

For each acceptible key, the value is extracted using IBinding.getObject() 55 . If the value is null, no attribute is written.

If the value is an instance of IAsset, then IAsset.buildURL(IRequestCycle) 55 is invoked to convert the asset to a URL.

Finally, IMarkupWriter.attribute(String,String) 55 is invoked with the value (or the URL).

The most common use for informal parameters is to support the HTML class attribute (for use with cascading style sheets) and to specify JavaScript event handlers.

Components are only required to generate attributes on the result phase; this can be skipped during the rewind phase.

getClassResolver

private org.apache.hivemind.ClassResolver getClassResolver()
Returns an object used to resolve classes.

Since:
3.0

getBinding

public IBinding getBinding(java.lang.String name)
Returns the named binding, or null if it doesn't exist.

This method looks for a JavaBeans property with an appropriate name, of type IBinding. The property should be named nameBinding. If it exists and is both readable and writable, then it is accessor method is invoked. Components which implement such methods can access their own binding through their instance variables instead of invoking this method, a performance optimization.

Specified by:
getBinding in interface IComponent

getChangeObserver

public org.apache.tapestry.event.ChangeObserver getChangeObserver()
Deprecated. To be removed in 3.1; use IPage.getChangeObserver() 55 .

Return's the page's change observer. In practical terms, this will be an org.apache.tapestry.engine.IPageRecorder.

getComponent

public IComponent getComponent(java.lang.String id)
Description copied from interface: IComponent
Retrieves an contained component by its id. Contained components have unique ids within their container.

Specified by:
getComponent in interface IComponent

getContainer

public IComponent getContainer()
Description copied from interface: IComponent
Returns the component which embeds the receiver. All components are contained within other components, with the exception of the root page component.

A page returns null.

Specified by:
getContainer in interface IComponent

setContainer

public void setContainer(IComponent value)
Description copied from interface: IComponent
Sets the container of the component. This is write-once, an attempt to change it later will throw an ApplicationRuntimeException.

Specified by:
setContainer in interface IComponent

getExtendedId

public java.lang.String getExtendedId()
Returns the name of the page, a slash, and this component's id path. Pages are different, they simply return their name.

Specified by:
getExtendedId in interface IComponent

getId

public java.lang.String getId()
Description copied from interface: IComponent
Returns the simple id of the component, as defined in its specification.

An id will be unique within the component which contains this component.

A page will always return null.

Specified by:
getId in interface IComponent

setId

public void setId(java.lang.String value)
Description copied from interface: IComponent
Sets the id of the component. This is write-once, an attempt to change it later will throw an ApplicationRuntimeException.

Specified by:
setId in interface IComponent

getIdPath

public java.lang.String getIdPath()
Description copied from interface: IComponent
Returns the qualified id of the component. This represents a path from the page to this component, showing how components contain each other.

A page will always return null. A component contained on a page returns its simple id. Other components return their container's id path followed by a period and their own name.

Specified by:
getIdPath in interface IComponent

getPage

public IPage getPage()
Description copied from interface: IComponent
Returns the page which ultimately contains the receiver. A page will return itself.

Specified by:
getPage in interface IComponent

setPage

public void setPage(IPage value)
Description copied from interface: IComponent
Sets the page which ultimiately contains the component. This is write-once, an attempt to change it later will throw an ApplicationRuntimeException.

Specified by:
setPage in interface IComponent

getSpecification

public org.apache.tapestry.spec.IComponentSpecification getSpecification()
Description copied from interface: IComponent
Returns the specification which defines the component.

Specified by:
getSpecification in interface IComponent

setSpecification

public void setSpecification(org.apache.tapestry.spec.IComponentSpecification value)
Description copied from interface: IComponent
Sets the specification used by the component. This is write-once, an attempt to change it later will throw an ApplicationRuntimeException.

Specified by:
setSpecification in interface IComponent

renderBody

public void renderBody(IMarkupWriter writer,
                       IRequestCycle cycle)
Renders all elements wrapped by the receiver.

Specified by:
renderBody in interface IComponent

setBinding

public void setBinding(java.lang.String name,
                       IBinding binding)
Adds the binding with the given name, replacing any existing binding with that name.

This method checks to see if a matching JavaBeans property (with a name of nameBinding and a type of IBinding) exists. If so, that property is updated. An optimized component can simply implement accessor and mutator methods and then access its bindings via its own instance variables, rather than going through getBinding(String) 55 .

Informal parameters should not be stored in instance variables if renderInformalParameters(IMarkupWriter, IRequestCycle) 55 is to be used. It relies on using the collection of bindings (to store informal parameters).

Specified by:
setBinding in interface IComponent

toString

public java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

getComponents

public java.util.Map getComponents()
Returns an unmodifiable java.util.Mapof components, keyed on component id. Never returns null, but may return an empty map. The returned map is immutable.

Specified by:
getComponents in interface IComponent

getAssets

public java.util.Map getAssets()
Description copied from interface: IComponent
Returns the asset map for the component, which may be empty but will not be null.

The return value is unmodifiable.

Specified by:

getAsset

public IAsset getAsset(java.lang.String name)
Description copied from interface: IComponent
Returns the named asset, or null if not found.

Specified by:
getAsset in interface IComponent

getBindingNames

public java.util.Collection getBindingNames()
Description copied from interface: IComponent
Returns a java.util.Collection of the names of all bindings (which includes bindings for both formal and informal parameters).

The return value is unmodifiable. It will be null for a page, or may simply be empty for a component with no bindings.

Specified by:
getBindingNames in interface IComponent

getBindings

public java.util.Map getBindings()
Returns a java.util.Mapof all bindings for this component. This implementation is expensive, since it has to merge the disassociated bindings (informal parameters, and parameters without a JavaBeans property) with the associated bindings (formal parameters with a JavaBeans property).

Specified by:
getBindings in interface IComponent
Since:
1.0.5

getListeners

public org.apache.tapestry.listener.ListenerMap getListeners()
Returns a org.apache.tapestry.listener.ListenerMapfor the component. A org.apache.tapestry.listener.ListenerMapcontains a number of synthetic read-only properties that implement the IActionListenerinterface, but in fact, cause public instance methods to be invoked.

Since:
1.0.2

getBeans

public IBeanProvider getBeans()
Returns the IBeanProviderfor this component. This is lazily created the first time it is needed.

Since:
1.0.4

Since:
1.0.5

render

public final void render(IMarkupWriter writer,
                         IRequestCycle cycle)
The main method used to render the component. Invokes prepareForRender(IRequestCycle) 55 , then renderComponent(IMarkupWriter, IRequestCycle) 55 . cleanupAfterRender(IRequestCycle) 55 is invoked in a finally block.

Subclasses should not override this method; instead they will implement renderComponent(IMarkupWriter, IRequestCycle) 55 .

Specified by:
render in interface IRender
Since:
2.0.3

prepareForRender

protected void prepareForRender(IRequestCycle cycle)
Invoked by render(IMarkupWriter, IRequestCycle) 55 to prepare the component to render. This implementation sets JavaBeans properties from matching bound parameters. Subclasses that override this method must invoke this implementation as well.

Since:
2.0.3

renderComponent

protected abstract void renderComponent(IMarkupWriter writer,
                                        IRequestCycle cycle)
Invoked by render(IMarkupWriter, IRequestCycle) 55 to actually render the component (with any parameter values already set). This is the method that subclasses must implement.

Since:
2.0.3

cleanupAfterRender

protected void cleanupAfterRender(IRequestCycle cycle)
Invoked by render(IMarkupWriter, IRequestCycle) 55 after the component renders, to clear any parameters back to null (or 0, or false, or whatever the correct default is). Primarily, this is used to ensure that the component doesn't hold onto any objects that could otherwise be garbage collected.
