void	expandToInclude(Span otherSpan)
static Span	fromValues(int val1, int val2) Safe way to construct Spans if you're not sure which value is higher.
int	hashCode()
boolean	isAfter(Span otherSpan) Returns true if this span starts after the otherSpan's end.
boolean	isBefore(Span otherSpan) Returns true if this span ends before the otherSpan starts.

Constructor Detail

Span

public Span(int s,
            int e)

This assumes that s <= e. Use fromValues if you can't guarantee this.

Span

public Span(Span... spans)

Creates a span that encloses all spans in the argument list. Behavior is undefined if given no arguments.

Method Detail

fromValues

public static Span fromValues(int val1,
                              int val2)

Safe way to construct Spans if you're not sure which value is higher.

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

expandToInclude

public void expandToInclude(Span otherSpan)

contains

public boolean contains(Span otherSpan)

Returns true if this span contains otherSpan. Endpoints on spans may match.

contains

public boolean contains(int i)

Returns true if i is inside this span. Note that the start is inclusive and the end is exclusive.

isBefore

public boolean isBefore(Span otherSpan)

Returns true if this span ends before the otherSpan starts.

Throws:
