                 Range range,
                 java.lang.Object rowKey,
                 java.lang.Object argument,
                 boolean last)
          throws java.io.IOException

Description copied from class: AbstractTreeDataModel

walk sub-model having row key argument as its root

Specified by:

walk in class AbstractTreeDataModel

Parameters:

context - faces context

dataVisitor - org.ajax4jsf.ajax.repeat.UIDataAdaptor.ComponentVisitor

range - TreeRange to constraint the walk

rowKey - row key to treat as root of sub-model

argument - implementation specific argument

last - boolean flag indicating whether we started our walk from last element

Throws:

java.io.IOException

ExtendedDataModel#walk(FacesContext, DataVisitor, Range, Object)}

walkModel

public void walkModel(javax.faces.context.FacesContext facesContext,

Description copied from class: AbstractTreeDataModel

Walk backing sub-model having row key argument as its root. If there is no backing model configured, calling this method is equivalent to calling AbstractTreeDataModel.walk(FacesContext, DataVisitor, Range, Object, Object, boolean)

Specified by:

walkModel in class AbstractTreeDataModel

Parameters:

facesContext - faces context

visitor - org.ajax4jsf.ajax.repeat.UIDataAdaptor.ComponentVisitor instance

key - row key to treat as root of sub-model

argument - implementation-specific argument

Throws:

Specified by:

getRowKey in class ExtendedDataModel

Returns:

setRowKey

public void setRowKey(java.lang.Object key)

Description copied from class: ExtendedDataModel

Instead of simple int for current state selection, this model can use any object for select current data. Implementation depend on model, with any restrictions :

1. key must be Serializable.
2. Object.toString() method must return representation compatible with UIComponent.getClientId(javax.faces.context.FacesContext), as far as this string will be appended to clientId of iterator component.

Specified by:

setRowKey in class ExtendedDataModel

Parameters:

key - key for select current data, or null for clear selection.
