The main class of the Java-client Crosstab Bean is the Crosstab
class, which is
defined in the oracle.dss.crosstab
package. The Crosstab
class extends
the oracle.dss.gridView.GridView
class, as does the Table
class.
The GridView
class extends oracle.dss.dataView.Dataview
.
The Dataview
class implements the DataviewCommon
interface.
The main class of the HTML-client Crosstab Bean is the ThinCrosstab
class,
which is defined in the oracle.dss.thin.beans.crosstab
package. The
ThinCrosstab
class extends oracle.dss.thin.beans.gridView.ThinGridView
class, as does the ThinTable
class. The ThinGridView
class extends
oracle.dss.thin.beans.dataView.ThinDataview
. The ThinDataView
class implements the ThinDataViewCommon
interface. The
ThinDataViewCommon
interface extends the DataviewCommon
interface.
Both the Java-client crosstab and the thin crosstab have PagingControl
components, which allow users to view different logical pages of data. The paging controls are
implemented differently for the Java-client crosstab and the thin crosstab, but in both cases,
you call getPagingControl
to get the paging control.
The following diagram illustrates these relationships.
Both the thin crosstab and the Java-client crosstab have header components that describe the
data in the crosstab and that allow users to manipulate the data. The column header component
class is ColPivotHeader
, and the row header component is the
RowPivotHeader
. Both classes extend CrosstabPivotHeader
. All three of
these classes are defined in oracle.dss.crosstab
. In both the
Crosstab
class and the ThinCrosstab
class, you call
getColumnHeader
to retrieve the column header, and you call
getRowHeader
to retrieve the row header for the crosstab. Both
getColumnHeader
and getRowHeader
return a GridViewHeader
. The CrosstabPivotHeader
implements the GridViewHeader
interface, so you can call any GridViewHeader
method to set properties of the headers in a thin crosstab or in a Java-client crosstab.
The following diagram illustrates the relationships between these classes and the
GridViewHeader
interface.
As with the headers, both the Java-client crosstab and the HTML-client crosstab have a
databody component. The CrosstabDatabody
class, which is defined in the
oracle.dss.crosstab
package, is the databody class for both the
Crosstab
and the ThinCrosstab
. You call getDatabody
to
retrieve the databody. The getDatabody
method returns a
GridViewDatabody
, which the CrosstabDatabody
implements. You can call
methods of the GridViewDatabody
to change the appearance of the databody.
The following diagram illustrates that the CrosstabDatabody
class implements
the GridViewDatabody
interface.
