  • Method Details

    • calculateNumberOfKotlinDefaultsMasks

      public static int calculateNumberOfKotlinDefaultsMasks(List<ParameterElement> parameters)
      The number of Kotlin defaults masks.
      Parameters:
      parameters - The parameters
      Returns:
      The number if masks
      Since:
      4.6.2

    • hasKotlinDefaultsParameters

      public static boolean hasKotlinDefaultsParameters(List<ParameterElement> arguments)
      Checks if parameter include Kotlin defaults.
      Parameters:
      arguments - The arguments
      Returns:
      true if include
      Since:
      4.6.2

    • hasDefaultsParameters

      public static boolean hasDefaultsParameters(List<ParameterElement> arguments)
      Checks if any parameter declares a default that this class knows how to honour, either through Kotlin's calling convention or through a caller-side default value.
      Parameters:
      arguments - The arguments
      Returns:
      true if any argument has a default this class can generate code for
      Since:
      5.2.0

    • hasAllDefaultsParameters

      public static boolean hasAllDefaultsParameters(List<ParameterElement> arguments)
      Checks whether every parameter has a default that this class can supply, so that a call may omit all of the arguments.

      This is stricter than every parameter merely reporting ParameterElement.hasDefault(): a language whose defaults are applied by the callee, without a calling convention this class implements, cannot have its arguments omitted here. Passing the default value of each parameter's type instead would silently construct an object with nulls and zeroes in place of the declared defaults.

      Parameters:
      arguments - The arguments
      Returns:
      true if all arguments can be defaulted by generated code
      Since:
      5.2.0

    • hasCallerSideDefaultsParameters

      public static boolean hasCallerSideDefaultsParameters(List<ParameterElement> arguments)
      Checks if any parameter has a default value that can be materialised at the call site.
      Parameters:
      arguments - The arguments
      Returns:
      true if any argument has a caller-side default value expression
      Since:
      5.2.0
