Enclosing class:

Precondition
```
public static class Precondition.NumericComparisonPrecondition
extends Precondition
```
A numeric comparison precondition is used for patterns containing a predicate that compares some expression E with a numeric constant. The expression E is evaluated as a characteristic, so that in a set of rules with predicates that compare E against different numeric constants, the expression E is only evaluated once.

    Description copied from class: Precondition
    
    Compute the value of the precondition for a given item. The item in question is the context item in the dynamic context held in the PreconditionMatcher
    
    Specified by:
    
    testPrecondition in class Precondition
    
    Parameters:
    
    matcher - the PreconditionMatcher: holds the dynamic context for evaluation.
    
    Returns:
    
    true if the precondition is satisfied
    
    Throws:
    
    XPathException - if evaluation of the precondition fails with a dynamic error
