Classes

AsciiCodec
An AsciiCodec allows encoding strings as ASCII bytes and decoding ASCII bytes to strings.
AsciiDecoder
AsciiEncoder
This class converts strings of only ASCII characters to bytes.
Base64Codec
A base64 encoder and decoder. [...]
Base64Decoder
Decoder for base64 encoded data. [...]
Base64Encoder
Base64 and base64url encoding converter. [...]
ByteConversionSink
The ByteConversionSink provides an interface for converters to efficiently transmit byte data. [...]
ByteConversionSinkBase
This class provides a base-class for converters that need to accept byte inputs.
ChunkedConversionSink<T>
A ChunkedConversionSink is used to transmit data more efficiently between two converters during chunked conversions. [...]
ClosableStringSink
A ClosableStringSink extends the StringSink interface by adding a close method.
Codec<S, T>
A Codec encodes and (if supported) decodes data. [...]
Converter<S, T>
A Converter converts data from one representation into another. [...]
Encoding
Open-ended Encoding enum.
HtmlEscape
Converter which escapes characters with special meaning in HTML. [...]
HtmlEscapeMode
HTML escape modes. [...]
JsonCodec
A JsonCodec encodes JSON objects to strings and decodes strings to JSON objects. [...]
JsonDecoder
This class parses JSON strings and builds the corresponding objects. [...]
JsonEncoder
This class converts JSON objects to strings.
JsonUtf8Encoder
Encoder that encodes a single object as a UTF-8 encoded JSON string. [...]
Latin1Codec
A Latin1Codec encodes strings to ISO Latin-1 (aka ISO-8859-1) bytes and decodes Latin-1 bytes to strings.
Latin1Decoder
This class converts Latin-1 bytes (lists of unsigned 8-bit integers) to a string.
Latin1Encoder
This class converts strings of only ISO Latin-1 characters to bytes.
LineSplitter
A StreamTransformer that splits a String into individual lines. [...]
SerdesJson
StringConversionSink
This class provides an interface for converters to efficiently transmit String data. [...]
StringConversionSinkBase
This class provides a base-class for converters that need to accept String inputs.
StringConversionSinkMixin
This class provides a mixin for converters that need to accept String inputs.
Utf8Codec
A Utf8Codec encodes strings to utf-8 code units (bytes) and decodes UTF-8 code units to strings.
Utf8Decoder
This class converts UTF-8 code units (lists of unsigned 8-bit integers) to a string.
Utf8Encoder
This class converts strings to their UTF-8 code units (a list of unsigned 8-bit integers).
