Method Detail

isPartOfSelect

protected boolean isPartOfSelect(RolapStar.Column col)

Description copied from class: AbstractQuerySpec

Allows subclasses to specify if a given column must be returned as part of the result set, in the select clause.

Overrides:

isPartOfSelect in class AbstractQuerySpec

isPartOfSelect

protected boolean isPartOfSelect(RolapStar.Measure measure)

Description copied from class: AbstractQuerySpec

Allows subclasses to specify if a given column must be returned as part of the result set, in the select clause.

Overrides:

isPartOfSelect in class AbstractQuerySpec

getMeasureCount

public int getMeasureCount()

getMeasure

public RolapStar.Measure getMeasure(int i)

getMeasureAlias

public String getMeasureAlias(int i)

getColumns

public RolapStar.Column[] getColumns()

getColumnAlias

public String getColumnAlias(int i)

getColumnPredicate

public StarColumnPredicate getColumnPredicate(int i)

Description copied from interface: QuerySpec

Returns the predicate on the ith column.

If the column is unconstrained, returns LiteralStarPredicate(true).

Parameters:

i - Column ordinal

Returns:

Constraint on column

generateSqlQuery

public Pair<String,List<SqlStatement.Type>> generateSqlQuery()

Specified by:

generateSqlQuery in interface QuerySpec

Overrides:

generateSqlQuery in class AbstractQuerySpec

addMeasure

protected void addMeasure(int i,
                          SqlQuery sqlQuery)

Description copied from class: AbstractQuerySpec

Adds a measure to a query.

Overrides:

addMeasure in class AbstractQuerySpec

Parameters:

i - Ordinal of measure

sqlQuery - Query object

isAggregate

protected boolean isAggregate()

Specified by:

isAggregate in class AbstractQuerySpec

isOrdered

protected boolean isOrdered()

Description copied from class: AbstractQuerySpec

Whether to add an ORDER BY clause to make results deterministic. Necessary if query returns more than one row and results are for human consumption.

Overrides:

isOrdered in class AbstractQuerySpec

Returns:

whether to sort query

getPredicateList

protected List<StarPredicate> getPredicateList()

Description copied from class: AbstractQuerySpec

Returns a list of predicates not associated with a particular column.

Overrides:

getPredicateList in class AbstractQuerySpec

Returns:

list of non-column predicates

extraPredicates

protected void extraPredicates(SqlQuery sqlQuery)

Description copied from class: AbstractQuerySpec

Adds predicates not associated with columns.

Overrides:

extraPredicates in class AbstractQuerySpec

Parameters:

sqlQuery - Query
