Method Detail

walk

public void walk(javax.faces.context.FacesContext context,
        DataVisitor visitor,
        Range range,
        Object argument)

Description copied from class: ExtendedDataModel

Iterate over model by "visitor" pattern, for given range

Specified by:

walk in class ExtendedDataModel<E>

Parameters:

context - current JSF context.

visitor - instance of DataVisitor, for process each row.

range - Implementation-specific range of data keys.

argument - Implementation-specific argument

getRowKey

public Object getRowKey()

Specified by:

getRowKey in class ExtendedDataModel<E>

Returns:

key for selected data or null

setRowKey

public void setRowKey(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<E>

Parameters:

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