ViewObjectOnRowSets

public ViewObjectOnRowSets()
Method Detail

create

protected void create()
Overrides:
create in class ComponentObjectImpl

getOuterValSupplier

public JIValueSupplier getOuterValSupplier(QueryCollection qc)

setSelectFromSources

public void setSelectFromSources(RowSet rs,
                                 AttributeDefImpl[] baseAttrDefs,
                                 RowSet[] selectSources,
                                 java.lang.String[] fromSourceNames,
                                 RowSet[] fromSources,
                                 JIParserNode whereParserNode,
                                 JIValueSupplier valueSupplier)

setDefaultAssocConsistent

protected void setDefaultAssocConsistent(boolean isEquiJoin)
Overrides:
setDefaultAssocConsistent in class ViewObjectImpl

executeQueryForCollection

protected void executeQueryForCollection(java.lang.Object qc,
                                         java.lang.Object[] params,
                                         int noUserParams)
Description copied from class: ViewObjectImpl
This method is invoked right before the row set executes the query. If this method is overridden, the custom logic will be applied to all row sets.

In contrast, if the user overrides the view object's executeQuery(), the custom logic in it only applies only when the user calls executeQuery() on the view object. If he calls executeQuery() on secondary row sets, the custom logic in executeQuery() will not apply.

Overrides:
executeQueryForCollection in class ViewObjectImpl
Parameters:
qc - the query collection about to execute the query.
params - the bind parameters that will be applied to the query.
noUserParams - the number of user bind parameters supplied through the setWhereClauseParam calls.

hasNextForCollection

protected boolean hasNextForCollection(java.lang.Object qc)
Overrides:
hasNextForCollection in class ViewObjectImpl

getNextMatchingRow

protected ViewRowImpl getNextMatchingRow(java.lang.Object qc)

getNextRow

protected ViewRowImpl getNextRow(java.lang.Object qc)

createRowFromResultSet

protected ViewRowImpl createRowFromResultSet(java.lang.Object qc,
                                             java.sql.ResultSet resultSet)
Overrides:
createRowFromResultSet in class ViewObjectImpl

retrieveByKey

protected Row[] retrieveByKey(ViewRowSetImpl rs,
                              Key key,
                              int maxNumOfRows,
                              boolean skipWhere)
Overrides:
retrieveByKey in class ViewObjectImpl

getQueryHitCount

public long getQueryHitCount(ViewRowSetImpl viewRowSet)
Description copied from class: ViewObjectImpl
Counts the number of rows that would be returned if the View Object were executed with the current query.

This method obtains the row count by executing:

    SELECT COUNT(1) FROM query-statement ESTCOUNT
 
Based on the value returned, you might want to adjust the JDBC row prefetch size.

Overrides:
getQueryHitCount in class ViewObjectImpl
Returns:
the number of rows.

getQueryHitCount

public long getQueryHitCount(ViewRowSetImpl viewRowSet,
                             Row[] masterRows)
Overrides:
getQueryHitCount in class ViewObjectImpl

getRowMatchBindValue

public java.lang.Object getRowMatchBindValue(Row row,
                                             java.lang.String varName)
Specified by:
getRowMatchBindValue in interface RowMatchBindValueSupplier
Overrides:
getRowMatchBindValue in class ViewObjectImpl
