Method Detail

### asCriterion

    public Object asCriterion()

  Description copied from interface: `BioSQLFeatureFilter`
  This method returns a Hibernate Criterion object that can be used to query the database.

  Specified by:
    `asCriterion` in interface `BioSQLFeatureFilter`
  Returns:
    a Hibernate Criterion object representing this filter.

### criterionAliasMap

    public Map criterionAliasMap()

  Description copied from interface: `BioSQLFeatureFilter`
  Returns a map of property names (keys) to aliases (values), if the criterion returned by asCriterion() uses aliases at all. If not, then it must at least return the empty map else you'll get NullPointerExceptions thrown elsewhere.

  Specified by:
    `criterionAliasMap` in interface `BioSQLFeatureFilter`
  Returns:

### equals

    public boolean equals(Object o)

  Overrides:
    `equals` in class `Object`

### accept

    public boolean accept(Feature f)

  Description copied from interface: `FeatureFilter`
  This method determines whether a feature is to be accepted.

  Specified by:
    `accept` in interface `FeatureFilter`
  Parameters:
    `f` - the Feature to evaluate
  Returns:
    true if this feature is to be selected in, or false if it is to be ignored

### hashCode

    public int hashCode()

  Overrides:
