Method Detail

subColumn

LongColumn subColumn(int fromIndex,
                     int toIndex)

Description copied from interface: Column

Returns a view of the portion of this column between the specified fromIndex, inclusive, and toIndex, exclusive. (If fromIndex and toIndex are equal, the returned list is empty.) The returned column is backed by this column.

Specified by:

subColumn in interface Column<Long>

Parameters:

fromIndex - low endpoint (inclusive) of the subList

toIndex - high endpoint (exclusive) of the subList

Returns:

a view of the specified range within this column

subColumn

LongColumn subColumn(Long fromElement,
                     boolean fromInclusive,
                     Long toElement,
                     boolean toInclusive)

Description copied from interface: Column

Returns a view of the portion of this column whose elements range from fromElement to toElement. If fromElement and toElement are equal, the returned column is empty unless fromInclusive and toInclusive are both true. The returned column is backed by this column.

This method is only available when Column.isDistinct() returns true.

Specified by:

subColumn in interface Column<Long>

Parameters:

fromElement - low endpoint of the returned column

fromInclusive - true if the low endpoint is to be included in the returned view

toElement - high endpoint of the returned column

toInclusive - true if the high endpoint is to be included in the returned view

Returns:

a view of the portion of this column whose elements range from fromElement to toElement

subColumn

LongColumn subColumn(Long fromElement,
                     Long toElement)

Description copied from interface: Column

Same behavior as Column#subColumn(Object, boolean, Object, Boolean), with fromInclusive set to true and toInclusive set to false.

This method is only available when Column.isDistinct() returns true.

Specified by:

subColumn in interface Column<Long>

Parameters:

fromElement - low endpoint of the returned column, inclusive

toElement - high endpoint of the returned column, exclusive

Returns:

view of the portion of this column whose elements range from fromElement, inclusive, to toElement, exclusive

head

LongColumn head(Long toElement,
                boolean inclusive)

Description copied from interface: Column

Returns a view of the portion of this column whose elements are less than (or equal to, if inclusive is true) toElement. The returned column is backed by this column.

This method is only available when Column.isDistinct() returns true.

Specified by:

head in interface Column<Long>

Parameters:

toElement - high endpoint of the returned column

inclusive - true if the high endpoint is to be included in the returned view

Returns:

a view of the portion of this column whose elements are less than (or equal to, if inclusive is true) toElement

head

LongColumn head(Long toElement)

Description copied from interface: Column

Same behavior as Column.head(Object, boolean), with inclusive set to false.

This method is only available when Column.isDistinct() returns true.

Specified by:

head in interface Column<Long>

Parameters:

toElement - high endpoint of the returned column

Returns:

a view of the portion of this column whose elements are less than toElement

tail

LongColumn tail(Long fromElement,
                boolean inclusive)

Description copied from interface: Column

Returns a view of the portion of this column whose elements are greater than (or equal to, if inclusive is true) fromElement. The returned column is backed by this column.

This method is only available when Column.isDistinct() returns true.

Specified by:

tail in interface Column<Long>

Parameters:

fromElement - low endpoint of the returned column

inclusive - true if the low endpoint is to be included in the returned view

Returns:

a view of the portion of this column whose elements are greater than or equal to fromElement

tail

LongColumn tail(Long fromElement)

Description copied from interface: Column

Same behavior as Column.tail(Object, boolean), with inclusive set to true.

This method is only available when Column.isDistinct() returns true.

Specified by:

tail in interface Column<Long>

Parameters:

fromElement - low endpoint of the returned column

Returns:

a view of the portion of this column whose elements are greater than or equal to fromElement

toHeap

LongColumn toHeap()

Description copied from interface: Column

Converts an index into a heap.

Specified by:

toHeap in interface Column<Long>

Returns:

a column equal to this one, but which reports Column.isSorted() as false. The resulting column shares the same underlying buffer as this one.

toSorted

LongColumn toSorted()

Description copied from interface: Column

Converts a heap to an index. The resulting column will have the same elements, but sorted in ascending order. The behavior of this method depends on the Column.characteristics() of this column:

• heap - checks if the column is already sorted. If so, returns a new column which shares the same underlying buffer, but with SORTED flag set. If not already sorted then Column.copy() will be invoked, and the resulting column will be sorted.
• sorted - returns this column
• distinct - returns a new column which shares the same underlying buffer, but with DISTINCT flag unset.

Specified by:

toSorted in interface Column<Long>

Returns:

a column with elements sorted in ascending order

append

LongColumn append(Column<Long> tail)

Description copied from interface: Column

Appends two columns with the same element type.

Both columns must have the same characteristics. If they're both unique indices then the first value of the provided column must be greater than the last value of this column.

Specified by:

append in interface Column<Long>

Parameters:

tail - - the column to be appended to the end of this column

Returns:

the provided column appended to the end of this column

copy

LongColumn copy()

Description copied from interface: Column

Returns a column equal to this one, but with elements stored in a newly allocated buffer.

Specified by:

copy in interface Column<Long>

Returns:

a column equal to this one, but with elements stored in a newly allocated buffer.
