GenericFunctionType class abstract

An anonymous function type.

functionType ::= TypeAnnotation? 'Function' TypeParameterList? FormalParameterList '?'?

where the FormalParameterList is being used to represent the following grammar, despite the fact that FormalParameterList can represent a much larger grammar than the one below. This is done in order to simplify the implementation.

parameterTypeList ::= () | ( normalParameterTypes ,? ) | ( normalParameterTypes , optionalParameterTypes ) | ( optionalParameterTypes ) namedParameterTypes ::= { namedParameterType (, namedParameterType)* ,? } namedParameterType ::= TypeAnnotation? SimpleIdentifier normalParameterTypes ::= normalParameterType (, normalParameterType)* normalParameterType ::= TypeAnnotation SimpleIdentifier? optionalParameterTypes ::= optionalPositionalParameterTypes | namedParameterTypes optionalPositionalParameterTypes ::= normalParameterTypes ,?

Clients may not extend, implement or mix-in this class.

Properties

beginToken → Token
Return the first token included in this node's source range.
no setterinherited
childEntities → Iterable<SyntacticEntity>
Return an iterator that can be used to iterate through all the entities (either AST nodes or tokens) that make up the contents of this node, including doc comments but excluding other comments.
no setterinherited
end → int
Return the offset of the character immediately following the last character of this node's source range.
no setterinherited
endToken → Token
Return the last token included in this node's source range.
no setterinherited
functionKeyword → Token
Return the keyword 'Function'.
no setter
hashCode → int
The hash code for this object.
no setterinherited
isSynthetic → bool
Return true if this node is a synthetic node.
no setterinherited
length → int
Return the number of characters in the syntactic entity's source range.
no setterinherited
offset → int
Return the offset from the beginning of the file to the first character in the syntactic entity.
no setterinherited
parameters → FormalParameterList
Return the parameters associated with the function type.
no setter
parent → AstNode?
Return this node's parent node, or null if this node is the root of an AST structure.
no setterinherited
question → Token?
The question mark indicating that the type is nullable, or null if there is no question mark.
no setterinherited
returnType → TypeAnnotation?
Return the return type of the function type being defined, or null if no return type was given.
no setter
root → AstNode
Return the node at the root of this node's AST structure.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
type → DartType?
Return the type being named, or null if the AST structure has not been resolved.
no setterinherited
typeParameters → TypeParameterList?
Return the type parameters for the function type, or null if the function type does not have any type parameters.
no setter

Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
inherited
findPrevious(Token target) → Token?
Return the token before target or null if it cannot be found.
inherited
getProperty<E>(String name) → E?
Return the value of the property with the given name, or null if this node does not have a property with the given name.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setProperty(String name, Object? value) → void
Set the value of the property with the given name to the given value. If the value is null, the property will effectively be removed.
inherited
thisOrAncestorMatching<E extends AstNode>(Predicate<AstNode> predicate) → E?
Return either this node or the most immediate ancestor of this node for which the predicate returns true, or null if there is no such node.
inherited
thisOrAncestorOfType<E extends AstNode>() → E?
Return either this node or the most immediate ancestor of this node that has the given type, or null if there is no such node.
inherited
toSource() → String
Return a textual description of this node in a form approximating valid source.
inherited
toString() → String
A string representation of this object.
inherited
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node.

Operators

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