      public EntityUtil()

  • Method Details

    • getFirst

      public static GenericValue getFirst(List<? extends GenericValue> values)

    • getOnly

      public static GenericValue getOnly(List<? extends GenericValue> values)

    • filterByDate

      public static <T extends GenericEntity> List<T> filterByDate(List<T> datedValues)
      returns the values that are currently active.
      Parameters:
      datedValues - GenericValue's that have "fromDate" and "thruDate" fields
      Returns:
      List of GenericValue's that are currently active

    • filterByDate

      public static <T extends GenericEntity> List<T> filterByDate(List<T> datedValues, boolean allAreSame)
      returns the values that are currently active.
      Parameters:
      datedValues - GenericValue's that have "fromDate" and "thruDate" fields
      allAreSame - Specifies whether all values in the List are of the same entity; this can help speed things up a fair amount since we only have to see if the from and thru date fields are valid once
      Returns:
      List of GenericValue's that are currently active

      datedValues - GenericValue's that have "fromDate" and "thruDate" fields
      moment - the moment in question
      Returns:
      List of GenericValue's that are active at the moment

    • filterByDate
