TYPE

static final Column.Type TYPE

Column type descriptor for primitive boolean columns.

Method Details

builder

static ColumnBoolean.Builder builder(ColumnName name)

Creates a boolean column builder for the supplied column name.

Parameters:

name - the column name

Returns:

a new boolean column builder

getType

default Column.Type getType()

Description copied from interface: Column

Returns the declared type of values stored in this column.

Specified by:

getType in interface Column

Returns:

the column value type

get

boolean get(int i)

Returns the boolean value at the supplied row.

Parameters:

i - the zero-based row index

Returns:

the boolean value

toArray

boolean[] toArray(boolean[] x)

Copies the values into the provided array, allocating a new array when necessary.

Parameters:

x - the destination array, or null

Returns:

an array containing the column values

compare

default int compare(int i,
 int j)

Description copied from interface: Column

Compares two row values from this column using the column's ordering semantics.

Specified by:

compare in interface Column

Parameters:

i - the first row index

j - the second row index

Returns:

a negative number, zero, or a positive number as the first row is less than, equal to, or greater than the second

selectRow

default Column selectRow(int i)

Description copied from interface: Column

Returns a single-row column containing the value from the supplied row.

Specified by:

selectRow in interface Column

Parameters:

i - the row to extract

Returns:

a single-row column with the same column name

toString

default String toString(int i)

Description copied from interface: Column

Formats the value at the supplied row for display.

Specified by:

toString in interface Column

Parameters:

i - the zero-based row index

Returns:

the formatted row value, or an empty string when unset

appendTo

default void appendTo(int i,
 StringBuilder out,
 ToStringSettings settings)

Description copied from interface: Column

Appends the value at the supplied row using the provided rendering settings.

Specified by:

appendTo in interface Column

Parameters:

i - the zero-based row index

out - the destination buffer

settings - formatting settings to apply

copy

default ColumnBoolean copy(ColumnName x)

Description copied from interface: Column

Creates a copy of this column with the supplied column name.

Specified by:

copy in interface Column

Parameters:

x - the name to assign to the copy

Returns:

a column containing the same values under the new name

select

default Selection select(Predicate<Boolean> predicate)

Selects rows whose values satisfy the supplied predicate.

Parameters:

predicate - the predicate to test against each set value

Returns:

a selection containing the predicate result for each row

predicate

default RowPredicate predicate(Column.Operator operator,
 CharSequence... values)

Description copied from interface: Column

Creates a row predicate by parsing the supplied comparison values according to this column's type.

Specified by:

predicate in interface Column

Parameters:

operator - comparison operator

values - comparison values as text

Returns:

predicate evaluated by row index

predicate

default RowPredicate predicate(Column.Operator operator,
 boolean... values)
