Callout

- com.nwalsh.saxon.Callout

All Implemented Interfaces:

java.lang.Comparable
```
public class Callout
extends java.lang.Object
implements java.lang.Comparable
```
A class for maintaining information about callouts.

To make processing callouts easier, they are parsed out of the input structure and stored in a sorted array. (The array is sorted according to the order in which the callouts occur.)

This class is just the little record that we store in the array for each callout.

  - compareTo
```
public int compareTo(java.lang.Object o)
```
    The compareTo method compares this Callout with another.
    
    Given two Callouts, A and B, A < B if:
    
    A.line < B.line, or
    
    A.line = B.line && A.col < B.col, or
    
    A.line = B.line && A.col = B.col && A.callout < B.callout
    
    Otherwise, they're equal.
