Method Details

from

public static IntInterval from(int newFrom)

This static from method allows IntInterval to act as a fluent builder for itself. It works in conjunction with the instance methods to(int) and by(int).

Usage Example:

 IntInterval interval1 = IntInterval.from(1).to(5);         // results in: 1, 2, 3, 4, 5.
 IntInterval interval2 = IntInterval.from(1).to(10).by(2);  // results in: 1, 3, 5, 7, 9.
 

to

public IntInterval to(int newTo)

This instance to method allows IntInterval to act as a fluent builder for itself. It works in conjunction with the static method from(int) and instance method by(int).

Usage Example:

 IntInterval interval1 = IntInterval.from(1).to(5);         // results in: 1, 2, 3, 4, 5.
 IntInterval interval2 = IntInterval.from(1).to(10).by(2);  // results in: 1, 3, 5, 7, 9.
 

by

public IntInterval by(int newStep)

This instance by method allows IntInterval to act as a fluent builder for itself. It works in conjunction with the static method from(int) and instance method to(int).

Usage Example:

 IntInterval interval1 = IntInterval.from(1).to(5);         // results in: 1, 2, 3, 4, 5.
 IntInterval interval2 = IntInterval.from(1).to(10).by(2);  // results in: 1, 3, 5, 7, 9.
 

zero

public static IntInterval zero()

Returns an IntInterval starting at zero.

Usage Example:

 IntInterval interval1 = IntInterval.zero().to(5);         // results in: 0, 1, 2, 3, 4, 5.
 IntInterval interval2 = IntInterval.zero().to(10).by(2);  // results in: 0, 2, 4, 6, 8, 10.
