Method Detail

subColumn

StringColumn 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<String>

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

StringColumn subColumn(String fromElement,
                       boolean fromInclusive,
                       String 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.isSortedSet() returns true.

Specified by:

subColumn in interface Column<String>

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

StringColumn subColumn(String fromElement,
                       String 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.isSortedSet() returns true.

Specified by:

subColumn in interface Column<String>

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

StringColumn head(String 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.isSortedSet() returns true.

Specified by:

head in interface Column<String>

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

StringColumn head(String 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.isSortedSet() returns true.

Specified by:

head in interface Column<String>

Parameters:

toElement - high endpoint of the returned column

Returns:

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

tail

StringColumn tail(String 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.isSortedSet() returns true.

Specified by:

tail in interface Column<String>

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

StringColumn tail(String 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.isSortedSet() returns true.

Specified by:

tail in interface Column<String>

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

builder

static StringColumnBuilder builder(boolean sortedSet)

of

static StringColumn of(String... elements)

collector
