clearCurrencyStringCache

@Deprecated
protected void clearCurrencyStringCache()

Deprecated. Have your Renderer implement ClientRowKeyManagerFactory and create your own UIGrid.DefaultClientKeyManager instances. Then you can manage the lifecycle of each key inside your ClientRowKeyManager. TODO - Need to figure out when to clear the entire key cache ( probably during events where the pt is refreshed completely ) TODO - As a further optimization, need to figure out when to prune the client key cache based on blocks. The table collects the keys from the client and sends them to the server to be pruned. TODO - Need to determine if the cache needs to be maintained for the selection state / stamp state to function.

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

encodeBegin

public final void encodeBegin(javax.faces.context.FacesContext context)
                       throws java.io.IOException

Clears all the currency strings.

Overrides:

encodeBegin in class org.apache.myfaces.trinidad.component.UIXComponentBase

Throws:

java.io.IOException

encodeEnd

public void encodeEnd(javax.faces.context.FacesContext context)
               throws java.io.IOException

Overrides:

encodeEnd in class org.apache.myfaces.trinidad.component.UIXComponentBase

Throws:

java.io.IOException

getClientCellKey

public java.lang.String getClientCellKey()

Gets a String version of the current cellkey. The contents of the String are controlled by the current UIGrid.DefaultClientKeyManager. This String can be passed into the setClientCellKey(java.lang.String) method to restore the current cellData. 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:

setClientCellKey(java.lang.String), getClientKeyManager(), UIGrid.DefaultClientKeyManager.getClientCellKey(javax.faces.context.FacesContext, javax.faces.component.UIComponent, oracle.adf.view.faces.bi.model.CellKey)

setClientCellKey

public void setClientCellKey(java.lang.String clientCellKey)

Restores this component's cellData to be what it was when the given client cellKey string was created.

See Also:

getClientCellKey()

getContainerClientId

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

For internal use only. 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:

getClientCellKey()

preCellDataChange

protected final void preCellDataChange()

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

postCellDataChange

protected void postCellDataChange()

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

getStamps

protected abstract 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.

saveStampState

protected java.lang.Object saveStampState(javax.faces.context.FacesContext context,
                                          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.

getDataModel

public final DataModel getDataModel()

Gets the DataModel to use with this component.

resetClientKeyManager

public void resetClientKeyManager()

Resets the ClientKeyManager.

getClientKeyManager

public final ClientKeyManager getClientKeyManager()

Gets the ClientKeyManager that is used to handle the getClientCellKey() and setClientCellKey(java.lang.String) methods. If the manager does not already exist a new one is created.

invokeOnComponent

public boolean invokeOnComponent(javax.faces.context.FacesContext context,
                                 java.lang.String clientId,

                          throws javax.faces.FacesException

Overrides:

invokeOnComponent in class org.apache.myfaces.trinidad.component.UIXComponentBase

Throws:

javax.faces.FacesException

getDataModel
