IntKindBase class abstract

Abstract base class for integer kinds.

Serialization

JSON

You can encode/decode JSON with jsonEncode and jsonDecode.

The JSON representation is JSON number.

Protocol Buffers / GRPC

See subclass documentation.

Generating random values

You can generate random values with the methods randomExample() and randomExampleList().

If min and max are non-null, the random values will be in the range. Otherwise values are in some range near zero.

This behavior may be changed in future.

Properties

bitsPerListElement → int

Number of bits per value or -1 if the number of bits undefined.

no setter, inherited

declaredExamples → List<int>

Returns declared examples of this value.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, override

isSerializable → bool

no setter, inherited

max → int?

Maximum valid value.

final, inherited

min → int?

Minimum valid value.

final, inherited

name → String

Name of this kind for debugging purposes.

no setter, inherited

protobufFieldType → int

Returns package:protobuf GeneratedMessage field type.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

unitOfMeasurement → UnitOfMeasurement?

Unit of measurement (for visualization purposes).

final, inherited

unsigned → bool

Whether the kind is unsigned (Uint32Kind, etc.).

no setter

Methods

getKind() → EntityKind<Object>

Returns Kind of this entity.

inherited

instanceCast(Object? value) → int

Casts the value to T or throws an error.

inherited

instanceIsCorrectType(Object? value) → bool

Tells whether the argument is an instance of the wanted Dart type.

inherited

instanceIsDefaultValue(Object? value) → bool

Tells whether the argument is a value returned by newInstance.

inherited

instanceIsValid(Object? value) → bool

A shorthand for checking validity with instanceValidate.

inherited

instanceValidate(ValidateContext context, Object? value) → void

Checks that the type is correct and then validates constraints with instanceValidateConstraints.

inherited

instanceValidateConstraints(ValidateContext context, int value) → void

Validates that the argument matches constraints (minimum length, etc.).

override

instanceValidateOrThrow(Object? value) → void

A shorthand for calling instanceValidate with the context ValidateContext.throwing().

inherited

jsonTreeDecode(Object? value, {JsonDecodingContext? context}) → int

Converts the argument (a JSON tree) into an instance of T.

override

jsonTreeEncode(int instance, {JsonEncodingContext? context}) → Object?

Converts the argument into a JSON tree.

override

newInstance() → int

Returns new default value.

override

newList(int length, {bool growable = false, bool reactive = true}) → List<int>

Returns a new list of this kind, which is guaranteed some properties.

inherited

newListFrom(Iterable<int> iterable, {bool growable = true, bool reactive = true}) → List<int>

A method similar to the list constructor List.from.

inherited

newListGenerate(int length, int function(int i), {bool growable = false, bool reactive = true}) → List<int>

A method similar to the list constructor List.generate.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

protobufNewInstance() → Object?

Constructs package:protobuf GeneratedMessage field value (e.g. bool, Int64, GeneratedMessage).

inherited

protobufTreeDecode(Object? value, {ProtobufDecodingContext? context}) → int

Converts the argument (a Protocol Buffers tree) into an instance of T.

override

protobufTreeEncode(int instance, {ProtobufEncodingContext? context}) → int

Converts the argument into a Protocol Buffers tree.

override

randomExample({RandomExampleContext? context}) → int

Generates a random example.

override

randomExampleList(int n, {RandomExampleContext? context}) → List<int>

Generates a list of N random examples (with randomExample).

inherited

toNonNullable() → Kind<int>

Returns a non-nullable version of this kind.

inherited

toNullable() → NullableKind<int>

Returns a nullable version of this kind.

inherited

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
