Interface InternalComponentResources

All Superinterfaces:

All Known Implementing Classes:

InternalComponentResourcesImpl

public interface InternalComponentResources
extends ComponentResources, InternalComponentResourcesCommon, RenderCommand

An extension of ComponentResources that represents additional methods that are private to the framework and not exposed in any public APIs.

Method Summary

void	addPageResetListener(PageResetListener listener) Delegates to Page.addResetListener(org.apache.tapestry5.internal.structure.PageResetListener).
java.lang.Object	getFieldChange(java.lang.String fieldName) Get the current persisted value of the field.
ParameterConduit	getParameterConduit(java.lang.String parameterName) Gets a previously stored ParameterConduit, allowing PCs to be shared between a component and a mixin of that component.
java.lang.String	getPropertyName(java.lang.String parameterName) Returns the name of the bound property if PropBinding is used and the expression points to a property on a bean (e.g.
boolean	hasFieldChange(java.lang.String fieldName) Checks to see if there is a value stored for the indicated field.
void	persistFieldChange(java.lang.String fieldName, java.lang.Object newValue) Posts a change to a persistent field.
void	postRenderCleanup() Allows the resources to cleanup any render-time only data.
void	setParameterConduit(java.lang.String parameterName, ParameterConduit conduit) Stores a ParameterConduit for later access.

Method Detail

getFieldChange

java.lang.Object getFieldChange(java.lang.String fieldName)

Get the current persisted value of the field.

Parameters:

fieldName - the name of the field to access

Returns:

the value stored for the field, or null if no value is currently stored

hasFieldChange

boolean hasFieldChange(java.lang.String fieldName)

Checks to see if there is a value stored for the indicated field.

persistFieldChange

void persistFieldChange(java.lang.String fieldName,
                        java.lang.Object newValue)

Posts a change to a persistent field. If the component is still loading, then this change is ignored. Otherwise, it is propagated, via the page to the PersistentFieldManager.

postRenderCleanup

void postRenderCleanup()

Allows the resources to cleanup any render-time only data.

addPageResetListener

void addPageResetListener(PageResetListener listener)

Delegates to Page.addResetListener(org.apache.tapestry5.internal.structure.PageResetListener).

Parameters:

listener - to register

getParameterConduit

ParameterConduit getParameterConduit(java.lang.String parameterName)

Gets a previously stored ParameterConduit, allowing PCs to be shared between a component and a mixin of that component.

Since:

5.2.0

setParameterConduit

void setParameterConduit(java.lang.String parameterName,
                         ParameterConduit conduit)

Stores a ParameterConduit for later access. Tthis occurs inside a component's PageLifecycleListener.containingPageDidLoad() lifecycle method.

Since:

5.2.0

getPropertyName

java.lang.String getPropertyName(java.lang.String parameterName)

Returns the name of the bound property if PropBinding is used and the expression points to a property on a bean (e.g. user.name). Otherwise this method returns null.

Parameters:

parameterName - name of the parameter

Since:

5.2.0
