An inline function argument definition.

Examples (multi-line):

void onClick() {
    DialogBox { message = "Hello!"; parent = this; }.show();
}

void onError(dynamic err)
        => console.error(err);

Initializer
FunctionArgument(LIdentifier name, Type|VoidModifier|FunctionModifier|DynamicModifier type, [Parameters+] parameterLists, Block|LazySpecifier definition)
Parameters:
  • name

    The name of the function, as well as of the parameter it’s assigned to.

  • type

    The type of the function.

    This can be:

    • a Type,
    • a void’ modifier (VoidModifier) for a function that does not return a value,
    • a function’ modifier (FunctionModifier) for a function with inferred type,
    • a dynamic’ modifier (DynamicModifier) for a dynamically typed function.
  • parameterLists

    The parameter lists of the function.

  • definition

    The definition of the function.

    If this is a LazySpecifier, then the argument is terminated by a semicolon.

Attributes
childrenshared actual [Type|VoidModifier|FunctionModifier|DynamicModifier, LIdentifier, <Parameters|Block|LazySpecifier>+] children

The child nodes of this node.

definitionshared Block|LazySpecifier definition

The definition of the function.

If this is a LazySpecifier, then the argument is terminated by a semicolon.

hashshared actual Integer hash

The hash value of the value, which allows the value to be an element of a hash-based set or key of a hash-based map. Implementations must respect the constraint that:

  • if x==y then x.hash==y.hash.

Therefore, a class which refines equals must also refine hash.

Because the Integer type is platform-dependent a compiler for a given platform is permitted to further manipulate the calculated hash for an object, and the resulting hash may differ between platforms.

Refines Object.hash
nameshared actual LIdentifier name

The name of the function, as well as of the parameter it’s assigned to.

parameterListsshared [Parameters+] parameterLists

The parameter lists of the function.

typeshared Type|VoidModifier|FunctionModifier|DynamicModifier type

The type of the function.

This can be:

  • a Type,
  • a void’ modifier (VoidModifier) for a function that does not return a value,
  • a function’ modifier (FunctionModifier) for a function with inferred type,
  • a dynamic’ modifier (DynamicModifier) for a dynamically typed function.

Methods
copyshared FunctionArgument copy(LIdentifier name = ..., Type|VoidModifier|FunctionModifier|DynamicModifier type = ..., [Parameters+] parameterLists = ..., Block|LazySpecifier definition = ...)
Parameters:
  • name = this.name
  • type = this.type
  • parameterLists = this.parameterLists
  • definition = this.definition
equalsshared actual Boolean equals(Object that)

Determine if two values are equal. Implementations should respect the constraints that:

  • if x===y then x==y (reflexivity),
  • if x==y then y==x (symmetry),
  • if x==y and y==z then x==z (transitivity).

Furthermore it is recommended that implementations ensure that if x==y then x and y have the same concrete class.

A class which explicitly refines equals() is said to support value equality, and the equality operator == is considered much more meaningful for such classes than for a class which simply inherits the default implementation of identity equality from Identifiable.

Refines Object.equals
transformshared actual Result transform<out Result>(Transformer<Result> transformer)

Transform this node with the given transformer by calling the appropriate transformX method on the transformer.

If you have a Node node that’s actually an LIdentifier instance, then the runtime will call LIdentifier.transform; therefore, this method is by nature narrowing. This means that if transformer is a NarrowingTransformer, calling node.transform(transformer) is equivalent to calling transformer.transformNode(node). On the other hand, if transformer is a WideningTransformer, then the two operations are very different.

visitshared actual void visit(Visitor visitor)

Visit this node with the given visitor. Calls the appropriate visitX method on the visitor.
