Class ProductionBuilder
Provides an API for fluently building productions.
public sealed class ProductionBuilder : IProductionBuilder<ProductionBuilder>, IProduction- Inheritance
-
ProductionBuilder
- Implements
- Extension Methods
Remarks
A production builder constructs IProduction<T>s by aggregating the types
of its significant members. The types of the production's significant members are indicated
by the type parameters. For example, a ProductionBuilder has no significant members,
and a ProductionBuilder<int, string> has two significant members: an integer
and a string.
Constructors
ProductionBuilder(params object[])
Creates a production builder with the given members.
public ProductionBuilder(params object[] members)Parameters
membersobject[]An array of the production's members.
Exceptions
- ArgumentException
membershas an item whose type is not IGrammarSymbol, string or char.
Properties
Empty
A production builder with no members.
public static ProductionBuilder Empty { get; }Property Value
Methods
Append(IGrammarSymbol)
Appends an IGrammarSymbol to the production.
public ProductionBuilder Append(IGrammarSymbol symbol)Parameters
symbolIGrammarSymbolThe symbol to append.
Returns
- ProductionBuilder
A production builder with
symboladded to the production's end.
Remarks
If symbol's actual type is a typed IGrammarSymbol<T>,
appending it to a production will not prevent its semantic actions from being
executed.
Extend<T1>(IGrammarSymbol<T1>)
Extends the production with a new significant member.
public ProductionBuilder<T1> Extend<T1>(IGrammarSymbol<T1> symbol)Parameters
symbolIGrammarSymbol<T1>The new significant member.
Returns
- ProductionBuilder<T1>
A production builder with
symboladded to its end as a significant member.
Type Parameters
T1The type of the new significant member.
FinishConstant<T>(T)
Finishes building a production, making it return a constant value.
public IProduction<T> FinishConstant<T>(T value)Parameters
valueTThe value to return from the production.
Returns
- IProduction<T>
Type Parameters
TThe type of the production's return value.
Finish<T>(Func<T>)
Finishes building a production, making it return a value produced by a function.
public IProduction<T> Finish<T>(Func<T> fuser)Parameters
fuserFunc<T>A function that produces the value of the production.
Returns
- IProduction<T>
Type Parameters
TThe type of the production's return value.
WithPrecedence(object)
Changes the precedence token of the production.
public ProductionBuilder WithPrecedence(object precedenceToken)Parameters
precedenceTokenobjectAn object that represents the production in associativity groups.
Returns
- ProductionBuilder
A production builder with the precedence token changed to
precedenceToken.
