TriGEncoderOptions class

Configuration options for TriG serialization.

This class provides configuration settings that control how RDF datasets are serialized to the TriG format, including namespace prefix handling and automatic prefix generation.

Example:

final options = TriGEncoderOptions(
  customPrefixes: {'ex': 'http://example.org/'},
  generateMissingPrefixes: true
);
final encoder = TriGEncoder(options: options);

Creates a new TriGEncoderOptions instance.

Properties

collectionItemBreakAfter → int
Maximum number of collection items before forcing a multi-line layout.
final
customPrefixes → Map<String, String>
Custom namespace prefixes to use during encoding.
finalinherited
generateMissingPrefixes → bool

no setterinherited
includeBaseDeclaration → bool
Whether to include base URI declarations in the output
final
inlineBlankNodeMaxTriples → int
Maximum number of triples inside an inline blank node before forcing multi-line layout.
final
inlineBlankNodeMaxWidth → int
Maximum inline length (in characters) for blank nodes.
final
iriRelativization → IriRelativizationOptions
Options for controlling IRI relativization behavior.
finalinherited
objectListBreakAfter → int
Maximum number of objects before breaking object lists across lines.
final
prettyPrintCollections → bool

final
renderFragmentsAsPrefixed → bool

final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
useGraphKeyword → bool
Whether to use the explicit GRAPH keyword for named graphs.
final
useNumericLocalNames → bool
Controls whether local names that start with a digit are written using prefix notation.

Methods

copyWith({Map<String, String>? customPrefixes, bool? generateMissingPrefixes, bool? useNumericLocalNames, bool? includeBaseDeclaration, bool? renderFragmentsAsPrefixed, bool? useGraphKeyword, bool? prettyPrintCollections, int? collectionItemBreakAfter, int? objectListBreakAfter, int? inlineBlankNodeMaxWidth, int? inlineBlankNodeMaxTriples, IriRelativizationOptions? iriRelativization}) → TriGEncoderOptions
This method allows creating a new TriGEncoderOptions instance based on the current options, selectively overriding specific fields while keeping all other settings unchanged.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.

Static Methods

from(RdfGraphEncoderOptions options) → TriGEncoderOptions
