Method Detail

asCopy

public static Row asCopy(Object... values)

Creates a Row.

Makes a defensive copy of the array, so the Row is immutable. (If you're worried about the extra copy, call of(Object). But the JIT probably avoids the copy.)

public static Row of(@Nullable Object value0)

Creates a Row with one column value.

of

public static Row of(@Nullable Object value0,
                     @Nullable Object value1)

Creates a Row with two column values.

of

public static Row of(@Nullable Object value0,
                     @Nullable Object value1,
                     @Nullable Object value2)

Creates a Row with three column values.
