public abstract class UIXCollection

extends UIXComponentBase

protected void clearCurrencyStringCache()

Deprecated. Have your Renderer implement ClientRowKeyManagerFactory and create your own ClientRowKeyManager instances. Then you can manage the lifecycle of each key inside your ClientRowKeyManager.

Clear the rowKey-to-currencyString cache. The cache is not cleared immediately; instead it will be cleared when encodeBegin(javax.faces.context.FacesContext) is called.

@Deprecated
public java.lang.String getCurrencyString()

Deprecated. use getClientRowKey

Deprecated. use setClientRowKey

See Also:

setClientRowKey(java.lang.String)

getClientRowKey

public java.lang.String getClientRowKey()

Gets a String version of the current rowkey. The contents of the String are controlled by the current ClientRowKeyManager. This String can be passed into the setClientRowKey(java.lang.String) method to restore the current rowData. The lifetime of this String is short and it may not be valid during future requests; however, it is guaranteed to be valid for the next subsequent request.

See Also:

setClientRowKey(java.lang.String), getClientRowKeyManager(), ClientRowKeyManager.getClientRowKey(javax.faces.context.FacesContext, javax.faces.component.UIComponent, java.lang.Object)

See Also:

getClientRowKey()

getContainerClientId

public final java.lang.String getContainerClientId(javax.faces.context.FacesContext context)

Gets the client-id of this component, without any NamingContainers. This id changes depending on the currency Object. Because this implementation uses currency strings, the local client ID is not stable for very long. Its lifetime is the same as that of a currency string.

Overrides:

getContainerClientId in class javax.faces.component.UIComponent

Returns:

the local clientId

See Also:

getClientRowKey()

preRowDataChange

protected final void preRowDataChange()

Prepares this component for a change in the rowData. This method should be called right before the rowData changes. It saves the internal states of all the stamps of this component so that they can be restored when the rowData is reverted.

postRowDataChange

protected final void postRowDataChange()

Sets up this component to use the new rowData. This method should be called right after the rowData changes. It sets up the var EL variable to be the current rowData. It also sets up the internal states of all the stamps of this component to match this new rowData.

protected java.util.List<javax.faces.component.UIComponent> getStamps()

Gets the UIComponents that are considered stamps. This implementation simply returns the children of this component.

Returns:

each element must be of type UIComponent.

                                          javax.faces.component.UIComponent stamp)

Saves the state of a stamp. This method is called when the currency of this component is changed so that the state of this stamp can be preserved, before the stamp is updated with the state corresponding to the new currency. This method recurses for the children and facets of the stamp.

Returns:

this object must be Serializable if client-side state saving is used.

restoreStampState

protected void restoreStampState(javax.faces.context.FacesContext context,
                                 javax.faces.component.UIComponent stamp,
                                 java.lang.Object stampState)

Restores the state of a stamp. This method is called after the currency of this component is changed so that the state of this stamp can be changed to match the new currency. This method recurses for the children and facets of the stamp.

processComponent

protected final void processComponent(javax.faces.context.FacesContext context,
                                      javax.faces.component.UIComponent component,
                                      javax.faces.event.PhaseId phaseId)

Process a component. This method calls processDecodes(javax.faces.context.FacesContext), UIXComponentBase.processValidators(javax.faces.context.FacesContext) or UIXComponentBase.processUpdates(javax.faces.context.FacesContext) depending on the {#link PhaseId}.

processFacetsAndChildren

protected abstract void processFacetsAndChildren(javax.faces.context.FacesContext context,
                                                 javax.faces.event.PhaseId phaseId)

Process this component's facets and children. This method should call processComponent(javax.faces.context.FacesContext, javax.faces.component.UIComponent, javax.faces.event.PhaseId) as many times as necessary for each facet and child. processComponent(javax.faces.context.FacesContext, javax.faces.component.UIComponent, javax.faces.event.PhaseId) may be called repeatedly for the same child if that child is being stamped.

getCollectionModel

protected final CollectionModel getCollectionModel()

Gets the CollectionModel to use with this component.

getClientRowKeyManager

public final ClientRowKeyManager getClientRowKeyManager()

Gets the ClientRowKeyManager that is used to handle the getClientRowKey() and setClientRowKey(java.lang.String) methods. If the manager does not already exist a new one is created. In order to create your own manager, your Renderer (for this component) must implement ClientRowKeyManagerFactory

Creates the CollectionModel to use with this component. The state of the UIComponent with the new model instance is not fully initialized until after this method returns. As a result, other component attributes that need a fully initialized model should not be initialized in this method.
