GenericFunctionType class

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.

Implemented types




beginToken Token
Return the first token included in this node's source range.
read-only, inherited
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.
read-only, inherited
end int
Return the offset of the character immediately following the last character of this node's source range. [...]
read-only, inherited
endToken Token
Return the last token included in this node's source range.
read-only, inherited
functionKeyword Token
Return the keyword 'Function'.
read / write
hashCode int
The hash code for this object. [...]
read-only, inherited
isSynthetic bool
Return true if this node is a synthetic node. [...]
read-only, inherited
length int
Return the number of characters in the syntactic entity's source range.
read-only, inherited
offset int
Return the offset from the beginning of the file to the first character in the syntactic entity.
read-only, inherited
parameters FormalParameterList
Return the parameters associated with the function type.
read / write
parent AstNode
Return this node's parent node, or null if this node is the root of an AST structure. [...]
read-only, inherited
question Token
The question mark indicating that the type is nullable, or null if there is no question mark.
read / write, inherited-getter
returnType TypeAnnotation
Return the return type of the function type being defined, or null if no return type was given.
read / write
root AstNode
Return the node at the root of this node's AST structure. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
type DartType
Return the type being named, or null if the AST structure has not been resolved.
read-only, inherited
typeParameters TypeParameterList
Return the type parameters for the function type, or null if the function type does not have any type parameters.
read / write


accept<E>(AstVisitor<E> visitor) → E
Use the given visitor to visit this node. [...]
findPrevious(Token target) Token
Return the token before target or null if it cannot be found.
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.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
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.
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.
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.
toSource() String
Return a textual description of this node in a form approximating valid source. [...]
toString() String
A string representation of this object. [...]
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node. [...]


operator ==(Object other) bool
The equality operator. [...]
