FSharp Union Helpers

F# Discriminated Union Helpers

Features

getAllDUCases

Returns all Discriminated Union cases for a type

(Type -> Obj) -> Type -> CreatedUnion list

Where

• (Type -> obj) is a function to call on non-union types which creates a value for that type. For an example see the generateDefaultTypeParameter function.
• Type is the union type
• CreatedUnion list is a list of union case objects created from the provided union type

matchUnionWithFunction

Calls the provided function with all Discriminative Union cases for a type

generateDefaultTypeParameter

Creates a value of the type passed in.

Type -> Obj

getTypesPublicSignature

Returns a types public signature for classes, records, enums, tuples, unions, etc.

Type -> PublicTypeSignature

Note: known issues

• not all types tested (move examples to Unit Tests)
• cases in union type signature could do with a more explicit domain model
• no guards or safety for nested types (recursion)

toSignatureString

Converts a types public signature from above to a printable string.

PublicTypeSignature -> string

Helpers with bindingflags for

• getUnionCases

Type -> UnionCaseInfo[]

• makeUnion

UnionCaseInfo -> obj List -> obj

• isUnion

Type -> bool
