Class UnaryHandler

Provides unary operation functions for use in HotMesh mapping rules. The functions facilitate unary operations such as logical negation, making a number positive or negative, and bitwise negation during the mapping process. Each transformation is a function that expects one input parameter from the prior row in the @pipe structure.

Remarks

Invoked in mapping rules using {@unary.<method>} syntax.

Methods

bitwise_not

  • bitwise_not(value): number

  • Returns the bitwise negation of a number using the bitwise NOT operator (~).

    Parameters

    • value: number

      The number to bitwise negate

    Returns number

    The bitwise negation of the value

    Example

    bitwise_not_value:
      "@pipe":
        - ["{a.output.data.value}"]
        - ["{@unary.bitwise_not}"]

negative

  • negative(value): number

  • Returns the negative representation of a number using the unary negation operator.

    Parameters

    • value: number

      The number to negate

    Returns number

    The negated number

    Example

    negative_value:
      "@pipe":
        - ["{a.output.data.value}"]
        - ["{@unary.negative}"]

not

  • not(value): boolean

  • Returns the logical negation of a boolean value.

    Parameters

    • value: boolean

      The boolean value to negate

    Returns boolean

    The negated boolean value

    Example

    not_value:
      "@pipe":
        - ["{a.output.data.value}"]
        - ["{@unary.not}"]

positive

  • positive(value): number

  • Returns the positive representation of a number using the unary plus operator.

    Parameters

    • value: number

      The number to convert

    Returns number

    The positive representation of the value

    Example

    positive_value:
      "@pipe":
        - ["{a.output.data.value}"]
        - ["{@unary.positive}"]
