ResultDataModel is a convenience implementation of DataModel that wraps a JSTL Result object, typically representing the results of executing an SQL query via JSTL tags.

 
 
 public class ResultDataModel extends DataModel<SortedMap<String,Object>> {
 
 
     // ------------------------------------------------------------ Constructors
 

    

Construct a new ResultDataModel with no specified wrapped data.

 
     public ResultDataModel() {
 
         this(null);
 
     }


    

Construct a new ResultDataModel wrapping the specified Result.

Parameters:
result Result to be wrapped (if any)
 
     public ResultDataModel(Result result) {
 
         super();
         setWrappedData(result);
 
     }
 
 
     // ------------------------------------------------------ Instance Variables
 
 
     // The current row index (zero relative)
     private int index = -1;
 
 
     // The Result we are wrapping
     private Result result = null;
 
 
     // The individual rows of this Result, each represented as a Map
     // with column names as keys and associated data values as values
     private SortedMap rows[] = null;
 
    // -------------------------------------------------------------- Properties


    

Return true if there is wrappedData available, and the current value of rowIndex is greater than or equal to zero, and less than the length of the array returned by calling getRows() on the underlying Result. Otherwise, return false.

Throws:
FacesException if an error occurs getting the row availability
 
    public boolean isRowAvailable() {
        if ( == null) {
	    return (false);
        } else if (( >= 0) && ( < .)) {
            return (true);
        } else {
            return (false);
        }
    }


    

If there is wrappedData available, return the length of the array returned by calling getRows() on the underlying Result. If no wrappedData is available, return -1.

Throws:
FacesException if an error occurs getting the row count
    public int getRowCount() {
        if ( == null) {
	    return (-1);
        }
        return (.);
    }


    

If row data is available, return the SortedMap array element at the index specified by rowIndex of the array returned by calling getRows() on the underlying Result. If no wrapped data is available, return null.

Note that, if a non-null Map is returned by this method, it will contain the values of the columns for the current row, keyed by column name. Column name comparisons must be performed in a case-insensitive manner.

Throws:
FacesException if an error occurs getting the row data
java.lang.IllegalArgumentException if now row data is available at the currently specified row index
    public SortedMap<String,ObjectgetRowData() {
        if ( == null) {
	    return (null);
        } else if (!isRowAvailable()) {
            throw new NoRowAvailableException();
        } else {
            //noinspection unchecked
            return ((SortedMap<String,Object>)[]);
        }
    }


    

Throws:
FacesException
 
    public int getRowIndex() {
        return ();
    }


    
 
    public void setRowIndex(int rowIndex) {
        if (rowIndex < -1) {
            throw new IllegalArgumentException();
        }
        int old = ;
         = rowIndex;
	if ( == null) {
	    return;
	}
        if ((old != ) && (listeners != null)) {
            SortedMap<String,ObjectrowData = null;
            if (isRowAvailable()) {
                rowData = getRowData();
            }
            DataModelEvent event =
                new DataModelEvent(thisrowData);
            int n = listeners.length;
            for (int i = 0; i < ni++) {
		if (null != listeners[i]) {
		    listeners[i].rowSelected(event);
		}
            }
        }
    }
    public Object getWrappedData() {
        return (this.);
    }


    

Throws:
java.lang.ClassCastException if data is non-null and is not a Result
    public void setWrappedData(Object data) {
        if (data == null) {
             = null;
             = null;
            setRowIndex(-1);
        } else {
             = (Resultdata;
             = .getRows();
             = -1;
            setRowIndex(0);
        }
