  • Field Details

  • Constructor Details

    • Facet

      protected Facet()
      Default constructor, provided only for JAXB serialization. Sub-classes should not expose a public default constructor.

    • Facet

      protected Facet(String name, boolean isVisible, String defaultOption, List<FacetOption<T>> options, int numOmittedOptions, int omittedOptionsDataCount, boolean isExclusiveOptions, String facetType, String sourceRef)
      Constructs a new facet.
      Parameters:
      name - The name of the facet.
      options - The list of options for this facet.
      isVisible - Whether or not the facet will appear to the user.
      defaultOption - The defaultOption to be applied.
      numOmittedOptions - The number of additional options that are available, but are not included in the provided list of options.
      omittedOptionsDataCount - The number of objects that contain data matched by the omitted options. This allows the UI to present the generic option "Other" along with a count.
      isExclusiveOptions - Whether this facet's options are exclusive or not. See isExclusiveOptions().
      facetType - Type of the facet (whether it is List or DateRange)
      sourceRef - Name of the field (of the record), on which the filter is applied.

      Specified by:
      isVisible in interface com.appiancorp.common.query.ReadOnlyFacet<T>
      Returns:
      whether or not this facet should be displayed to the user.

    • getDefaultOption

      public String getDefaultOption()
      Specified by:
      getDefaultOption in interface com.appiancorp.common.query.ReadOnlyFacet<T>

      the default applied option for the facet.

    • getNumOmittedOptions

      public int getNumOmittedOptions()
      Specified by:
      getNumOmittedOptions in interface com.appiancorp.common.query.ReadOnlyFacet<T>
      Returns:
      The number of options that exist, but are not included in the list of options. If this number is not available, returns FacetOption.COUNT_NOT_AVAILABLE.

    • getTotalNumOptions

      public int getTotalNumOptions()
      Returns:
      The number of options plus the number of omitted options. If the number of omitted options is not available, returns FacetOption.COUNT_NOT_AVAILABLE.

    • getOmittedOptionsDataCount

      public int getOmittedOptionsDataCount()
      Specified by:
      getOmittedOptionsDataCount in interface com.appiancorp.common.query.ReadOnlyFacet<T>
      Returns:
      The number of objects that have a value for this facet that matches one of the omitted options. If this number is not available, returns FacetOption.COUNT_NOT_AVAILABLE.

    • isExclusiveOptions

      public boolean isExclusiveOptions()
      Specified by:
      isExclusiveOptions in interface com.appiancorp.common.query.ReadOnlyFacet<T>
      Returns:
      true if the options are exclusive, and false otherwise. If the options are exclusive, only one of the options can be applied for a given query. If the options are not exclusive, multiple options can be selected and applied in a given query. This is analogous to radio buttons vs checkboxes.
