java.lang.Object
oracle.iam.rm.temporal.query.ColumnSetDef

public class ColumnSetDef

extends java.lang.Object

A structure to allow definition of how search result columns should be provided and how it should be sorted.

Nested Class Summary

class	ColumnSetDef.SortEntry A structure to allow description of how the results should be sorted.
static class	ColumnSetDef.SortOrder Static variables for sort order, asc or desc for ascending or descending sort order.

Constructor Summary

ColumnSetDef()
Creates a ColumnSetDef instance.

ColumnSetDef(boolean unique)
Creates a ColumnSetDef instance where the results will be guaranteed unique by the database.

Method Summary

void	addAggregateColumn(java.lang.String resultObjectKey, java.lang.String resultObjectAttributeKey, java.lang.String columnKey, ColumnDef.AggregateFunction aggregateFunction) Requests an attribute value to be included in the result set rows, the vaue of which is determined by an aggregate function.

Constructor Detail

ColumnSetDef

public ColumnSetDef()

Creates a ColumnSetDef instance.

ColumnSetDef

public ColumnSetDef(boolean unique)

Creates a ColumnSetDef instance where the results will be guaranteed unique by the database. Warning: This has performance impacts with large sets of results.

Parameters:

unique - either true for the results to be guaraneed unique or false.

Method Detail

addColumn

public void addColumn(java.lang.String resultObjectKey,
                      java.lang.String resultObjectAttributeKey)

Requests an attribute value to be included in the result set rows.

Parameters:

resultObjectKey - identifying key of the object from the query definition from which to extract the attribute

resultObjectAttributeKey - attribute key from the specified object to include

addColumn

public void addColumn(java.lang.String resultObjectKey,
                      java.lang.String resultObjectAttributeKey,
                      java.lang.String columnKey)

Requests an attribute value to be included in the result set rows.

Parameters:

resultObjectKey - identifying key of the object from the query definition from which to extract the attribute

resultObjectAttributeKey - attribute key from the specified object to include

columnKey - identifying key that the attribute value will be referred to in each result set row

addAggregateColumn

public void addAggregateColumn(java.lang.String resultObjectKey,
                               java.lang.String resultObjectAttributeKey,
                               java.lang.String columnKey,
                               ColumnDef.AggregateFunction aggregateFunction)

Requests an attribute value to be included in the result set rows, the vaue of which is determined by an aggregate function.

Parameters:

resultObjectKey - identifying key of the object from the query definition form which to extract the attribute

resultObjectAttributeKey - attribute key from the specified object to include

columnKey - identifying key that the attribute value will be referred to in each result set row

aggregateFunction - the aggregate function whose result will be in the column specified

resetSort

public void resetSort()

Resets the sort orders, if secondary and additional sort orders were added.

See Also:

addSort(java.lang.String, java.lang.String, oracle.iam.rm.temporal.query.ColumnSetDef.SortOrder)

addSort

public void addSort(java.lang.String resultObjectKey,
                    java.lang.String resultObjectAttributeKey,
                    ColumnSetDef.SortOrder direction)

Requests the results be sorted by a particular attribute's value. This can be called multiple times in order to add secondary sort orders, and so forth. To start from scratch use the resetSort() method.

Parameters:

resultObjectKey - identifying key of the object from the query definition from which to sort the attribute

resultObjectAttributeKey - attribute key from the specified object to sort on

direction - sort order, either asc or desc

Returns:

true to return unique results, false to allow repeats

setUnique

public void setUnique(boolean unique)

Sets whether the results returned should be "unique".

Parameters:
