Returns the length of the range.

equals

public boolean equals(java.lang.Object object)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

object - the reference object with which to compare.

normalize

public static IndexRange normalize(int v1,
                   int v2)

Convenience method to create an IndexRange instance that has the smaller value as the start index, and the larger value as the end index.

Parameters:

v1 - The first value to use in the range.

v2 - The second value to use in the range.

Returns:

A IndexRange instance where the smaller value is the start, and the larger value is the end.

valueOf

public static IndexRange valueOf(java.lang.String value)

Convenience method to parse in a String of the form '2,6', which will create an IndexRange instance with a start value of 2, and an end value of 6.

Parameters:

value - The string to be parsed, and converted to an IndexRange.

Returns:

An IndexRange instance representing the start and end values provided in the value string.
