Method Detail

subColumn

BooleanColumn 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<Boolean>

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

append

BooleanColumn append(Column<Boolean> 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<Boolean>

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

BooleanColumn 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<Boolean>

Returns:

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

builder

static BooleanColumnBuilder builder()

getBoolean

boolean getBoolean(int index)

Primitive specialization of List.get(int).

Parameters:

index - - index of the value to return

Returns:

the boolean value at the specified index.

Throws:

IndexOutOfBoundsException - if index is negative or is not less than List.size()

of

static BooleanColumn of(Boolean... elements)

Returns a new BooleanColumn containing the specified elements.

Parameters:

elements - the elements to be included in the new column

Returns:

a new BooleanColumn containing the specified elements.

collector

static Collector<Boolean,?,BooleanColumn> collector()

Collects a stream of Booleans into a new BooleanColumn.

Returns:

a new BooleanColumn
