- Method Detail
  - getDecimalSortComparerInstance
```
public static DecimalSortComparer getDecimalSortComparerInstance()
```
  - getComparisonKey
```
public ComparisonKey getComparisonKey(AtomicValue a)
```
    Get a comparison key for an object. This must satisfy the rule that if two objects are equal as defined by the XPath eq operator, then their comparison keys are equal as defined by the Java equals() method, and vice versa. There is no requirement that the comparison keys should reflect the ordering of the underlying objects.
