  • Method Details

    • minus

      public static Operation minus(Expression e)
      Creates an unary minus operation.
      Parameters:
      e - The expression to which the unary minus should be applied. We don't check if it's a numeric expression, but in hindsight to generate semantically correct Cypher, it's recommended that is one.
      Returns:
      An unary minus operation.

    • plus

      public static Expression plus(Expression e)
      Creates an unary plus operation.
      Parameters:
      e - The expression to which the unary plus should be applied. We don't check if it's a numeric expression, but in hindsight to generate semantically correct Cypher, it's recommended that is one.
      Returns:
      An unary plus operation.

    • set

      public static Operation set(Expression target, Expression value)
      Creates a = operation. The left hand side should resolve to a property or to something which has labels or types to modify and the right hand side should either be new properties or labels.
      Parameters:
      target - The target that should be modified
      value - The new value of the target
      Returns:
      A new operation.

    • mutate

      public static Operation mutate(Expression target, MapExpression value)
      Creates a += operation. The left hand side must resolve to a container (either a node or a relationship) of properties and the right hand side must be a map of new or updated properties
      Parameters:
      target - The target container that should be modified
      value - The new properties
      Returns:
      A new operation.
