Method Details

ungrouped

public final UngroupedColumnSource<COMPONENT_TYPE> ungrouped()

Specified by:

ungrouped in interface AggregateColumnSource<VECTOR_TYPE extends Vector<VECTOR_TYPE>,COMPONENT_TYPE>

startTrackingPrevValues

public final void startTrackingPrevValues()

Description copied from interface: ColumnSource

ColumnSource implementations that track previous values have the option to not actually start tracking previous values until this method is called. This is an option, not an obligation: some simple ColumnSource implementations (like TSingleValueSource for various T) always track previous values; other implementations (like PrevColumnSource) never do; some (like TArrayColumnSource) only start tracking once this method is called. An immutable column source can not have distinct prev values; therefore it is implemented as a no-op.

Specified by:

startTrackingPrevValues in interface ColumnSource<VECTOR_TYPE extends Vector<VECTOR_TYPE>>

isStateless

public boolean isStateless()

Description copied from interface: ColumnSource

Most column sources will return the same value for a given row without respect to the order that the rows are read. Those columns sources are considered "stateless" and should return true. Some column sources, however may be dependent on evaluation order. For example, a formula that updates a Map must be evaluated from the first row to the last row. A column source that has the potential to depend on the order of evaluation must return false.

Specified by:

isStateless in interface ColumnSource<VECTOR_TYPE extends Vector<VECTOR_TYPE>>

Returns:

true if this is a stateless column source

isImmutable

public boolean isImmutable()

Description copied from interface: ColumnSource

Determine if this column source is immutable, meaning that the values at a given row key never change.

Specified by:

isImmutable in interface ColumnSource<VECTOR_TYPE extends Vector<VECTOR_TYPE>>

Specified by:

isImmutable in interface MutableColumnSource<VECTOR_TYPE extends Vector<VECTOR_TYPE>>

Returns:

true if the values at a given row key of the column source never change, false otherwise
