Properties

IsLiteral

True, if the rule contributes characters, otherwise false

public override bool IsLiteral { get; }

Property Value

bool

Regex

Gets or sets the regular expression

public Regex Regex { get; set; }

Property Value

Regex

TokenType

Gets the token type of tokens created for this rule

public override string TokenType { get; }

Property Value

string

Methods

CanStartWith(Rule, List<Rule>)

Indicates whether the rule could start with the given other rule

protected override bool CanStartWith(Rule rule, List<Rule> trace)

Parameters

rule Rule

the other rule

trace List<Rule>

a list of rules visited so far

Returns

bool

true, if the rule could start with the given other rule, otherwise false

CanSynthesize(object, ParseContext, SynthesisPlan)

Determines whether the current rule can synthesize rule applications for the given semantic element

public override bool CanSynthesize(object semanticElement, ParseContext context, SynthesisPlan synthesisPlan)

Parameters

semanticElement object

the semantic element

context ParseContext

the context in which the rule is synthesized

synthesisPlan SynthesisPlan

the plan of the synthesis

Returns

bool

true, if a rule application can be synthesized, otherwise false

CreateRuleApplication(string, ParsePosition, ParsePositionDelta, ParseContext)

Creates a new rule application

public virtual RuleApplication CreateRuleApplication(string matched, ParsePosition position, ParsePositionDelta examined, ParseContext context)

Parameters

matched string

the matched string content

position ParsePosition

the position where the rule matched

examined ParsePositionDelta

the examined length of text

context ParseContext

the parse context

Returns

RuleApplication

a rule application

IsEpsilonAllowed(List<Rule>)

Determines whether the rule could capture empty input

protected override bool IsEpsilonAllowed(List<Rule> trace)

Parameters

trace List<Rule>

Returns

bool

true, if the rule can be expanded to an empty string, otherwise false

Match(ParseContext, RecursionContext, ref ParsePosition)

Matches the the context at the provided position

public override RuleApplication Match(ParseContext context, RecursionContext recursionContext, ref ParsePosition position)

Parameters

context ParseContext

the context in which the rule is matched

recursionContext RecursionContext

the recursion context of the matching

position ParsePosition

the position in the input

Returns

RuleApplication

the rule application for the provided position

Synthesize(object, ParsePosition, ParseContext)

Synthesizes a rule application for the given semantic element

public override RuleApplication Synthesize(object semanticElement, ParsePosition position, ParseContext context)

Parameters

semanticElement object

position ParsePosition

the parse position at which the element should be synthesized

context ParseContext

the parse context

Returns

RuleApplication

a rule application
