- - org.apache.tools.ant.types.EnumeratedAttribute
  - - org.apache.tools.ant.types.Quantifier

-     public class Quantifier
      extends EnumeratedAttribute

  EnumeratedAttribute for quantifier comparisons. Evaluates a `boolean[]` or raw `true` and `false` counts. Accepts the following values:
  "all"
    none `false`
  "each"
    none `false`
  "every"
    none `false`
  "any"
    at least one `true`
  "some"
    at least one `true`
  "one"
    exactly one `true`
  "majority"
    more `true` than `false`
