TransportableData class abstract interface

Transportable Encoded Data (TED) - encoded binary data for transport.

Represents binary data encoded as a string for easy transmission, implementing TransportableResource for serialization.

Supported formats: 0. Pure Base64 string: "{BASE64_ENCODE}"

  1. Data URI format: "data:image/png;base64,{BASE64_ENCODE}"

Methods

allMatches(String string, [int start = 0]) → Iterable<Match>
Matches this pattern against the string repeatedly.
inherited
codeUnitAt(int index) → int
Returns the 16-bit UTF-16 code unit at the given index.
inherited
compareTo(String other) → int
Compares this object to another object.
inherited
contains(Pattern other, [int startIndex = 0]) → bool
Whether this string contains a match of other.
inherited
endsWith(String other) → bool
Whether this string ends with other.
inherited
indexOf(Pattern pattern, [int start = 0]) → int
Returns the position of the first match of pattern in this string, starting at start, inclusive:
inherited
lastIndexOf(Pattern pattern, [int? start]) → int
The starting position of the last match pattern in this string.
inherited
matchAsPrefix(String string, [int start = 0]) → Match?
Matches this pattern against the start of string.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
padLeft(int width, [String padding = ' ']) → String
Pads this string on the left if it is shorter than width.
inherited
padRight(int width, [String padding = ' ']) → String
Pads this string on the right if it is shorter than width.
inherited
replaceAll(Pattern from, String replace) → String
Replaces all substrings that match from with replace.
inherited
replaceAllMapped(Pattern from, String replace(Match match)) → String
Replace all substrings that match from by a computed string.
inherited
replaceFirst(Pattern from, String to, [int startIndex = 0]) → String
Creates a new string with the first occurrence of from replaced by to.
inherited
replaceFirstMapped(Pattern from, String replace(Match match), [int startIndex = 0]) → String
Replace the first occurrence of from in this string.
inherited
replaceRange(int start, int? end, String replacement) → String
Replaces the substring from start to end with replacement.
inherited
serialize() → Object
Serializes this TED to a transportable string (same as toString).
override
split(Pattern pattern) → List<String>
Splits the string at matches of pattern and returns a list of substrings.
inherited
splitMapJoin(Pattern pattern, {String onMatch(Match)?, String onNonMatch(String)?}) → String
Splits the string, converts its parts, and combines them into a new string.
inherited
startsWith(Pattern pattern, [int index = 0]) → bool
Whether this string starts with a match of pattern.
inherited
substring(int start, [int? end]) → String
The substring of this string from start, inclusive, to end, exclusive.
inherited
toLowerCase() → String
Converts all characters in this string to lower case.
inherited
toString() → String
Returns the encoded string representation of the data.
override
toUpperCase() → String
Converts all characters in this string to upper case.
inherited
trim() → String
The string without any leading and trailing whitespace.
inherited
trimLeft() → String
The string without any leading whitespace.
inherited
trimRight() → String
The string without any trailing whitespace.
inherited

Operators

operator *(int times) → String
Creates a new string by concatenating this string with itself a number of times.
inherited
operator +(String other) → String
Creates a new string by concatenating this string with other.
inherited
operator ==(Object other) → bool
The equality operator.
inherited
operator [](int index) → String
The character (as a single-code-unit String) at the given index.
