Constructors

MinimalECIInput(String stringToEncode, Encoding? priorityCharset, int fnc1)

Constructs a minimal input

Properties

bytes ↔ List<int>

getter/setter pair

fnc1 → int

final

fnc1Character → int

no setter

hashCode → int

The hash code for this object.

no setter, inherited

length → int

Returns the length of this input. The length is the number of bytes, FNC1 characters or ECIs in the sequence.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

charAt(int index) → int

Returns the byte value at the specified index. An index ranges from zero to length - 1. The first byte value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

override

getECIValue(int index) → int

Returns the int ECI value at the specified index. An index ranges from zero to length - 1. The first byte value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

override

haveNCharacters(int index, int n) → bool

override

isECI(int index) → bool

Determines if a value is an ECI

override

isFNC1(int index) → bool

Determines if a value is the FNC1 character

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

subSequence(int start, int end) → String

Returns a CharSequence that is a subsequence of this sequence. The subsequence starts with the char value at the specified index and ends with the char value at index end - 1. The length (in chars) of the returned sequence is end - start, so if start == end then an empty sequence is returned.

override

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Properties

costPerECI → int

final

Static Methods

addEdge(List<List<InputEdge?>> edges, int to, InputEdge edge) → void

addEdges(String stringToEncode, ECIEncoderSet encoderSet, List<List<InputEdge?>> edges, int from, InputEdge? previous, int fnc1) → void

encodeMinimally(String stringToEncode, ECIEncoderSet encoderSet, int fnc1) → List<int>
