getRowData
in classDataModel<Map<String,
Object>> - Returns:
- The object associated with the current row index.
-
getRowIndex
public int getRowIndex()Description copied from class:DataModel
Get the current row index.- Specified by:

in classDataModel<Map<String,
Object>> - Returns:
- The current row index.
-
getWrappedData
Description copied from class:DataModel
Get the entire collection of data associated with this component. Note that the actual type of the returned object depends upon the concrete subclass of DataModel; the object will represent an "ordered sequence of components", but may be implemented as an array, java.util.List, java.sql.ResultSet or other similar types.- Specified by:

in classDataModel<Map<String,
Object>> - Returns:
- the wrapped object.
