    • withExtension

      public final ImmutableCross withExtension(AdvancedExtension value)
      Copy the current immutable object by setting a present value for the optional extension attribute.
      Parameters:
      value - The value for extension
      Returns:
      A modified copy or this if not changed

    • withExtension

      public final ImmutableCross withExtension(Optional<? extends AdvancedExtension> optional)
      Copy the current immutable object by setting an optional value for the extension attribute. A shallow reference equality check is used on unboxed optional value to prevent copying of the same value by returning this.
      Parameters:
      optional - An optional value for extension
      Returns:
      A modified copy or this if not changed

    • withRemap

      public final ImmutableCross withRemap(Rel.Remap value)
      Copy the current immutable object by setting a present value for the optional remap attribute.
      Parameters:
      value - The value for remap
      Returns:
      A modified copy or this if not changed

    • withRemap

      public final ImmutableCross withRemap(Optional<? extends Rel.Remap> optional)
      Copy the current immutable object by setting an optional value for the remap attribute. A shallow reference equality check is used on unboxed optional value to prevent copying of the same value by returning this.
      Parameters:
      optional - An optional value for remap
      Returns:
      A modified copy or this if not changed

    • withCommonExtension

      public final ImmutableCross withCommonExtension(AdvancedExtension value)
      Copy the current immutable object by setting a present value for the optional commonExtension attribute.
      Parameters:
      value - The value for commonExtension
      Returns:
      A modified copy or this if not changed

    • withCommonExtension

      public final ImmutableCross withCommonExtension(Optional<? extends AdvancedExtension> optional)
      Copy the current immutable object by setting an optional value for the commonExtension attribute. A shallow reference equality check is used on unboxed optional value to prevent copying of the same value by returning this.
      Parameters:
      optional - An optional value for commonExtension
      Returns:
      A modified copy or this if not changed

    • withHint

      public final ImmutableCross withHint(Hint value)
      Copy the current immutable object by setting a present value for the optional hint attribute.
      Parameters:
      value - The value for hint
      Returns:
      A modified copy or this if not changed

    • withHint

      public final ImmutableCross withHint(Optional<? extends Hint> optional)
      Copy the current immutable object by setting an optional value for the hint attribute. A shallow reference equality check is used on unboxed optional value to prevent copying of the same value by returning this.
      Parameters:
      optional - An optional value for hint
      Returns:
      A modified copy or this if not changed

    • withLeft

      public final ImmutableCross withLeft(Rel value)
      Copy the current immutable object by setting a value for the left attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for left
      Returns:
      A modified copy or the this object

    • withRight

      public final ImmutableCross withRight(Rel value)
      Copy the current immutable object by setting a value for the right attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for right
      Returns:
      A modified copy or the this object

    • equals

      public boolean equals(Object another)
      This instance is equal to all instances of ImmutableCross that have equal attribute values.
      Overrides:
      equals in class Object
      Returns:
      true if this is equal to another instance

    • hashCode

      public int hashCode()
      Computes a hash code from attributes: extension, remap, commonExtension, hint, left, right.
      Overrides:
      hashCode in class Object
      Returns:
      hashCode value

    • toString

      public String toString()
      Prints the immutable value Cross with attribute values.
      Overrides:
      toString in class Object
      Returns:
      A string representation of the value

    • copyOf

      public static ImmutableCross copyOf(Cross instance)
      Creates an immutable copy of a Cross value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.
      Parameters:
      instance - The instance to copy
      Returns:
      A copied immutable Cross instance

    • builder

      public static ImmutableCross.Builder builder()
      Creates a builder for ImmutableCross. 
       ImmutableCross.builder()
    .extension(Optional<io.substrait.extension.AdvancedExtension>) // optional extension
    .remap(Optional<io.substrait.relation.Rel.Remap>) // optional remap
    .commonExtension(Optional<io.substrait.extension.AdvancedExtension>) // optional commonExtension
    .hint(Optional<io.substrait.hint.Hint>) // optional hint
    .left(io.substrait.relation.Rel) // required left
