Clones this RowComponentInfo.

Specified by:

clone in class ComponentInfo

Returns:

The clone of this RowComponentInfo.

setRow

public void setRow(int row)

Sets the row. This method allows reuse of this RowComponentInfo.

Parameters:

row - The row for which you want to use this RowComponentInfo.

getRow

equals

public boolean equals(java.lang.Object o)

Indicates whether the specified object is equivalent to this RowComponentInfo. RowComponentInfo objects are equivalent if they refer to the same row.

Overrides:

equals in class java.lang.Object

Parameters:

o - The object to compare with this RowComponentInfo.

Returns:

true if both objects refer to the same row, false if not or if o is not a RowComponentInfo.

getQDR

public QDR getQDR(DataAccess dataAccess,
                  int flags)

Retrieves a QDR for this RowComponentInfo. The QDR identifies the dimension members for the data row for which this RowComponentInfo provides information.

For example, say you have the following row header in a crosstab.

Boston	January 2000
	February 2000
Paris	January 2000
	February 2000

In a RowComponentInfo for the first row in the databody that corresponds to this row header, the QDR limits Geography to Boston, and it limits Time to January 2000.

Specified by:

getQDR in class ComponentInfo

Parameters:

dataAccess - The DataAccess that provided the data for the row that this RowComponentInfo describes.

flags - A constant that identifies whether to include page edge information if the QDR is not for the page edge. Valid constants are listed in the See Also section.

Returns:

A QDR that identifies the column of data that this RowComponentInfo describes.

hashCode

public int hashCode()

Specified by:

hashCode in class ComponentInfo

toString

public java.lang.String toString()

Produces a String that identifies the row.
