Method Detail

min

public long min()

Return the minimum value of the long range.

Returns:

the minimum value of the long range

max

public long max()

Return the maximum value of the long range.

Returns:

the maximum value of the long range

stream

public LongStream stream()

Returns a sequential ordered LongStream from min() (inclusive) to max() (exclusive) by an incremental step of 1.

An equivalent sequence of increasing values can be produced sequentially using a for loop as follows:

for (long i = range.min(); i < range.max(); ++i) { ... }

Returns:

a sequential LongStream for the range of long elements

of

public static LongRange of(long min,
                           long max)

Create a new LongRange object with the given min and max values.

Parameters:

min - the lower bound of the long range

max - the upper bound of the long range

Returns:

a new LongRange object

Throws:

IllegalArgumentException - if min > max

of

public static LongRange of(long value)

Return a new (half open) range, which contains only the given value: [value, value + 1).

Parameters:

value - the value of the created (half open) integer range

Returns:

a new (half open) range, which contains only the given value
