BrotliCodec class - brotli library

Constructors

BrotliCodec({int level = BrotliOption.defaultLevel, int mode = BrotliOption.defaultMode, int windowBits = BrotliOption.defaultWindowBits, int? blockBits, int? postfixBits, bool literalContextModeling = true, int sizeHint = 0, bool largeWindow = false, int? directDistanceCodeCount, bool ringBufferReallocation = true, int inputBufferLength = CodecBufferHolder.autoLength, int outputBufferLength = CodecBufferHolder.autoLength}): Construct an BrotliCodec that is configured with the following parameters.

Properties

bindingVersion → BrotliVersion: Return the base binding version this binding code was developed for.
no setter
blockBits → int?: Recommended input block size. Encoder may reduce this value, e.g. if the input is much smalltalk than the input block size. Range: BrotliOption.minBlockBits..BrotliOption.maxBlockBits. Default: nil (dynamically computed).
final
decoder → Converter<List<int>, List<int>>: Return the brotli decoder configured implementation.
no setteroverride
decoderVersion → BrotliVersion: Return the decoder library version.
no setter
directDistanceCodeCount → int?: Recommended number of direct distance codes. Encoder may change this value. Default: nil (dynamically computed).
final
encoder → Converter<List<int>, List<int>>: Return the brotli encoder configured implementation.
no setteroverride
encoderVersion → BrotliVersion: Return the encoder library version.
no setter
hashCode → int: The hash code for this object.
no setterinherited
inputBufferLength → int: Length in bytes of the buffer used for input data.
final
inverted → Codec<List<int>, List<int>>: Inverts this.
no setterinherited
largeWindow → bool: Flag that determines if "Large Window Brotli" is used. If set to true, then the LZ-Window can be set up to 30-bits but the result will not be RFC7932 compliant. Default: false
final
level → int: The compression-level or quality can be set in the range of BrotliOption.minLevel..BrotliOption.maxLevel. The higher the level, the slower the compression. Default: BrotliOption.defaultLevel
final
literalContextModeling → bool: Flag that affects usage of "literal context modeling" format feature. This flag is a "decoding-speed vs compression ratio" trade-off. Default: true
final
mode → int: Tune the encoder for a specific input. The allowable values are: BrotliOption.fontMode, BrotliOption.genericMode, BrotliOption.textMode, BrotliOption.defaultMode. Default: BrotliOption.defaultMode.
final
outputBufferLength → int: Length in bytes of the buffer used for processed output data.
final
postfixBits → int?: Recommended number of postfix bits. Encode may change this value. Range: BrotliOption.minPostfixBits..BrotliOption.maxPostfixBits Default: nil (dynamically computed).
final
ringBufferReallocation → bool: Flag the determines if "canny" ring buffer allocation is enabled. Ring buffer is allocated according to window size, despite the real size of content.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sizeHint → int: Estimated total input size for all encoding compress stream calls. Default: 0 (means the total input size if unknown).
final
windowBits → int: Recommended sliding LZ77 windows bit size. The encoder may reduce this value if the input is much smaller than the windows size. Range: BrotliOption.minWindowBits..BrotliOption.maxWindowBits Default: BrotliOption.defaultWindowBits.
final
