Enum FilterStrategy

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<FilterStrategy>
    public enum FilterStrategy
extends java.lang.Enum<FilterStrategy>
    An enum to distinguish between different strategies to execute the filter expression

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      AUTO
      AUTO analyzes the filter expression and splits it up into sub-expressions executed by different strategies.
      DB
      DB executes the filter expression in DB.
      POST
      POST executes the filter expression in memory after loading the whole graph.
      STREAM
      STREAM executes the filter expression in memory visiting vertices/edges.

      • AUTO

        public static final FilterStrategy AUTO
        AUTO analyzes the filter expression and splits it up into sub-expressions executed by different strategies.

      • POST

        public static final FilterStrategy POST
        POST executes the filter expression in memory after loading the whole graph.

      • STREAM

        public static final FilterStrategy STREAM
        STREAM executes the filter expression in memory visiting vertices/edges. TODO how to describe it ?

      • DB

        public static final FilterStrategy DB
        DB executes the filter expression in DB.

    • Method Detail

      • values

        public static FilterStrategy[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (FilterStrategy c : FilterStrategy.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static FilterStrategy valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
