Class FeatureFilter.ShadowContainedByLocation

  • All Implemented Interfaces:
    java.io.Serializable, FeatureFilter, OptimizableFilter
    Enclosing interface:
    FeatureFilter

    public static final class FeatureFilter.ShadowContainedByLocation
    extends java.lang.Object
    implements OptimizableFilter
    A filter that accepts all features whose shadow is contained by a specified Location. The shadow is defined as the interval between the minimum and maximum positions of the feature's location. For features with contiguous locations, this filter is equivalent to FeatureFilter.ContainedByLocation.

      • ShadowContainedByLocation

        public ShadowContainedByLocation​(Location loc)
        Creates a filter that returns everything contained within loc.
        Parameters:
        loc - the location that will contain the accepted features
    • Method Detail

      • getLocation

        public Location getLocation()
      • accept

        public boolean accept​(Feature f)
        Returns true if the feature is within this filter's location.
        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
      • equals

        public boolean equals​(java.lang.Object o)
        Overrides:
        equals in class java.lang.Object
      • hashCode

      • isProperSubset

        public boolean isProperSubset​(FeatureFilter sup)
        Description copied from interface: OptimizableFilter
        Returns true if this filter is a proper subset of sup - that is, for every feature that matches this, it also matches sup. The empty filter is a proper subset of all filters. All filters are a proper subset of the all filter. All filters are proper subsets of themselves.
        Specified by:
        isProperSubset in interface OptimizableFilter
        Parameters:
        sup - the potential super set
        Returns:
        true if sup contains all features contained by this filter
      • isDisjoint

        public boolean isDisjoint​(FeatureFilter filt)
        Description copied from interface: OptimizableFilter
        Returns true if this filter is disjoint from filt - that is, there is no Feature that is accepted by both filters. The empty filter is disjoint from all other filters. The all filter is disjoint from none.
        Specified by:
        isDisjoint in interface OptimizableFilter
      • toString

        Overrides:
        toString in class java.lang.Object
