Class OptionalType

constructor

• new OptionalType(typeParameter): OptionalType

• Parameters

  • typeParameter: Type

  Returns OptionalType

Static ClassName

getClassName

• getClassName(): string

• Returns string

isAssignableFrom

• isAssignableFrom(type): boolean

• Inspired from: https://docs.microsoft.com/en-us/dotnet/api/system.type.isassignablefrom For (most) generics, type invariance is expected (assumed) - neither covariance, nor contravariance are supported yet (will be supported in a next release).

  One exception though: for OptionType, we simulate covariance for missing (not provided) values. For example, Option is assignable from Option<?>. For more details, see the implementation of OptionType and @OptionalType.

  Parameters

  • type: Type

  Returns boolean
