Method Details

getLong

public long getLong(long index)

Description copied from interface: ElementSource

Get the value at the index as a long.

Specified by:

getLong in interface ElementSource<Long>

Parameters:

index - the location in index space to get the value from.

Returns:

the long at the index, null values are represented by QueryConstants.NULL_LONG

getPrevLong

public long getPrevLong(long index)

Description copied from interface: ElementSource

Get the previous value at the index as a long. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevLong in interface ElementSource<Long>

Specified by:

getPrevLong in interface ImmutableColumnSource<Long>

Parameters:

index - the location in index space to get the previous value from.

Returns:

the previous long at the index, null values are represented by QueryConstants.NULL_LONG

isImmutable

public boolean isImmutable()

Description copied from interface: ColumnSource

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

Specified by:

isImmutable in interface ColumnSource<Long>

Specified by:

isImmutable in interface ImmutableColumnSource<Long>

Returns:

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