Source class

A source that records can be read and decoded from.

Constructors

Source({List<Map<String, Object?>>? baseSpecs, Map<String, Object?>? codec, bool? doesNotNeedSplitting, SourceMetadata? metadata, Map<String, Object?>? spec})

Source.fromJson(Map json_)

Properties

baseSpecs ↔ List<Map<String, Object?>>?

While splitting, sources may specify the produced bundles as differences against another source, in order to save backend-side memory and allow bigger jobs.

getter/setter pair

codec ↔ Map<String, Object?>?

The codec to use to decode data read from the source.

getter/setter pair

doesNotNeedSplitting ↔ bool?

Setting this value to true hints to the framework that the source doesn't need splitting, and using SourceSplitRequest on it would yield SOURCE_SPLIT_OUTCOME_USE_CURRENT.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

metadata ↔ SourceMetadata?

Optionally, metadata for this source can be supplied right away, avoiding a SourceGetMetadataOperation roundtrip (see SourceOperationRequest).

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

spec ↔ Map<String, Object?>?

The source to read from, plus its parameters.

getter/setter pair

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
