copy

protected PartitionAwareSourceTable copy()

Description copied from class: LiveAttributeMap

Create a copy of this with initially-shared LiveAttributeMap.mutableAttributes.

Specified by:

copy in class LiveAttributeMap<Table,PartitionAwareSourceTable>

redefine

protected final BaseTable<?> redefine(@NotNull
 @NotNull TableDefinition newDefinition)

Description copied from class: RedefinableTable

Redefine this table with a subset of its current columns.

Specified by:

redefine in class RedefinableTable<PartitionAwareSourceTable>

Parameters:

newDefinition - A TableDefinition with a subset of this RedefinableTable's ColumnDefinitions.

Returns:

redefine

protected final Table redefine(TableDefinition newDefinitionExternal,
 TableDefinition newDefinitionInternal,
 SelectColumn[] viewColumns)

Description copied from class: RedefinableTable

Redefine this table with a subset of its current columns, with a potentially-differing definition to present to external interfaces and one or more select columns to apply.

Specified by:

redefine in class RedefinableTable<PartitionAwareSourceTable>

Parameters:

newDefinitionExternal - A TableDefinition that represents the results of redefine(newDefinitionInternal).view(viewColumns).

newDefinitionInternal - A TableDefinition with a subset of this RedefinableTable's ColumnDefinitions.

viewColumns - A set of SelectColumns to apply in order to transform a table with newDefinitionInternal to a table with newDefinitionExternal.

Returns:

filterLocationKeys

protected final Collection<ImmutableTableLocationKey> filterLocationKeys(@NotNull
 @NotNull Collection<ImmutableTableLocationKey> foundLocationKeys)

Description copied from class: SourceTable

Hook to allow found location keys to be filtered (e.g. according to a where-clause on the partitioning columns of a PartitionAwareSourceTable. The default implementation returns its input unmolested.

Overrides:

filterLocationKeys in class SourceTable<PartitionAwareSourceTable>

Parameters:

foundLocationKeys - A collection of ImmutableTableLocationKeys fetched from the TableLocationProvider, but not yet incorporated into the table

Returns:

A sub-collection of the input

where

public Table where(Filter filter)

Specified by:

where in interface TableOperations<Table,Table>

Overrides:

where in class UncoalescedTable<PartitionAwareSourceTable>

selectDistinct

public final Table selectDistinct(@NotNull
 @NotNull Collection<? extends Selectable> columns)

Specified by:

selectDistinct in interface TableOperations<Table,Table>

Overrides:

selectDistinct in class UncoalescedTable<PartitionAwareSourceTable>
