valueToString

valueToString(x): string
Parameters
- x: null
Returns string

buildTypeTable

buildTypeTable(typeTable): void
Parameters
- typeTable: TypeTable
Returns void

- Defined in node_modules/@dfinity/candid/lib/cjs/idl.d.ts:49

checkType

checkType(t): types.IDL.Type<any>
Parameters
- t: types.IDL.Type<any>
Returns types.IDL.Type<any>

- Defined in node_modules/@dfinity/candid/lib/cjs/idl.d.ts:71

_buildTypeTableImpl

_buildTypeTableImpl(typeTable): void
Parameters
- typeTable: TypeTable
Returns void

Parameters
- v: types.IDL.Visitor<D, R>
- d: D
Returns R
Overrides PrimitiveType.accept
- Defined in node_modules/@dfinity/candid/lib/cjs/idl.d.ts:125

covariant

covariant(x): x is null
Assert that JavaScript's x is the proper type represented by this Type.
Parameters

encodeValue

encodeValue(): ArrayBuffer

decodeValue

decodeValue(b, t): null
Parameters
- b: utils.candid.PipeArrayBuffer
- t: types.IDL.Type<any>
Returns null
