Method Details

getFilter

@Nullable
public Filter getFilter()

See Also:

• for usage.

setFilter

public CursorBuildSpec.CursorBuildSpecBuilder setFilter(@Nullable
 Filter filter)

See Also:

• for usage. All Filter#getRequiredColumns() must be explicitly added to #virtualColumns if virtual or, if set to a non-null value, #physicalColumns.

getInterval

public org.joda.time.Interval getInterval()

See Also:

• for usage.

setInterval

public CursorBuildSpec.CursorBuildSpecBuilder setInterval(org.joda.time.Interval interval)

See Also:

• for usage.

getPhysicalColumns

@Nullable
public Set<String> getPhysicalColumns()

See Also:

• for usage.

setPhysicalColumns

public CursorBuildSpec.CursorBuildSpecBuilder setPhysicalColumns(@Nullable
 Set<String> physicalColumns)

See Also:

• for usage. The backing value is not automatically populated by calls to #setFilter(Filter), #setVirtualColumns(VirtualColumns), #setAggregators(List), or #setPreferredOrdering(List), so this must be explicitly set for all required physical columns. If set to null, then a CursorHolder must assume that ALL columns are required

getVirtualColumns

public VirtualColumns getVirtualColumns()

See Also:

• for usage. All VirtualColumn#requiredColumns() must be explicitly added to #physicalColumns if it is set to a non-null value.

setVirtualColumns

public CursorBuildSpec.CursorBuildSpecBuilder setVirtualColumns(VirtualColumns virtualColumns)

See Also:

• for usage.

getGroupingColumns

@Nullable
public List<String> getGroupingColumns()

See Also:

• for usage.

setGroupingColumns

public CursorBuildSpec.CursorBuildSpecBuilder setGroupingColumns(@Nullable
 List<String> groupingColumns)

See Also:

• for usage.

getAggregators

@Nullable
public List<AggregatorFactory> getAggregators()

See Also:

• for usage.

setAggregators

public CursorBuildSpec.CursorBuildSpecBuilder setAggregators(@Nullable
 List<AggregatorFactory> aggregators)

See Also:

• for usage. All AggregatorFactory#requiredFields() must be explicitly added to #virtualColumns if virtual or, if set to a non-null value, #physicalColumns.

getPreferredOrdering

public List<OrderBy> getPreferredOrdering()

See Also:

• for usage.

setPreferredOrdering

public CursorBuildSpec.CursorBuildSpecBuilder setPreferredOrdering(List<OrderBy> preferredOrdering)

See Also:

• for usage. All OrderBy#getColumnName() must be explicitly added to #virtualColumns if virtual or, if set to a non-null value, #physicalColumns.

getQueryContext

public QueryContext getQueryContext()

See Also:

• CursorBuildSpec.getQueryContext()

setQueryContext

public CursorBuildSpec.CursorBuildSpecBuilder setQueryContext(QueryContext queryContext)

See Also:

• CursorBuildSpec.getQueryContext()

getQueryMetrics

@Nullable
public QueryMetrics<?> getQueryMetrics()

See Also:

• CursorBuildSpec.getQueryMetrics()

setQueryMetrics

public CursorBuildSpec.CursorBuildSpecBuilder setQueryMetrics(@Nullable
 QueryMetrics<?> queryMetrics)

See Also:

• CursorBuildSpec.getQueryMetrics()

andFilter

public CursorBuildSpec.CursorBuildSpecBuilder andFilter(Filter filterToAdd)

Adds a Filter to the builder, if filter is already set, the existing and new filters will be combined with an AndFilter. If physicalColumns is set, Filter.getRequiredColumns() which are not present in virtualColumns will be added to the existing set of physicalColumns.

build

public CursorBuildSpec build()
