  • Method Details

    • create

      public static AssignValue create(Column target, Expression value)
      Creates a value assignment to a Column given an Expression.
      Parameters:
      target - target column, must not be null.
      value - assignment value, must not be null.
      Returns:
      the AssignValue.

    • getColumn

      public Column getColumn()
      Returns:
      the target Column.

    • getValue

      public Expression getValue()
      Returns:
      the value to assign.

    • toString

      public String toString()
      Description copied from interface: Segment
      Return a SQL string representation of this Segment.

      The representation is intended for debugging purposes and an approximation to the generated SQL. While it might work in the context of a specific dialect, you should not assume that the Segment.toString() representation works across multiple databases.

      Specified by:
      toString in interface Segment
      Returns:
      a SQL string representation of this Segment.

    • visit

      public void visit(Visitor visitor)
      Description copied from interface: Visitable
      Accept a Visitor visiting this Visitable and its nested Visitables if applicable.
      Specified by:
      visit in interface Visitable
      Parameters:
      visitor - the visitor to notify, must not be null.

    • hashCode

      public int hashCode()
      Description copied from interface: Segment
      Generate a hash code from thisSegment.

      Hashcode typically derives from the Segment.toString() representation so two Segments yield the same Segment.hashCode() if their Segment.toString() representation matches.

      Specified by:
      hashCode in interface Segment
      Overrides:
      hashCode in class Object
      Returns:
      a hash code value for this object.

    • equals

      public boolean equals(@Nullable Object obj)
      Description copied from interface: Segment
      Check whether this Segment is equal to another Segment.

      Equality is typically given if the Segment.toString() representation matches.

      Specified by:
      equals in interface Segment
      Overrides:
      equals in class Object
      Parameters:
      obj - the reference object with which to compare.
      Returns:
      true if this object is the same as the other argument; false otherwise.
