ExtensionOverride class abstract
An override to force resolution to choose a member from a specific extension.
extensionOverride ::= Identifier TypeArgumentList? ArgumentList
Clients may not extend, implement or mix-in this class.
- Implemented types
Constructors
Properties
- argumentList → ArgumentList
-
Return the list of arguments to the override. In valid code this will
contain a single argument, which evaluates to the object being extended.
no setter
- 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
- extendedType → DartType?
-
Return the actual type extended by this override, produced by applying
typeArgumentTypes to the generic type extended by the extension.
no setter
- extensionName → Identifier
-
Return the name of the extension being selected.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- inConstantContext → bool
-
An expression e is said to occur in a constant context,
no setterinherited
- isAssignable → bool
-
Return
true
if this expression is syntactically valid for the LHS of an AssignmentExpression.no setterinherited - isNullAware → bool
-
Whether this override is null aware (as opposed to non-null).
no setter
- 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
- parent → AstNode?
-
Return this node's parent node, or
null
if this node is the root of an AST structure.no setterinherited - precedence → Precedence
-
Return the precedence of this expression.
no setterinherited
- 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
- staticElement → ExtensionElement?
-
Return the forced extension element.
no setter
- staticParameterElement → ParameterElement?
-
If this expression is an argument to an invocation, and the AST structure
has been resolved, and the function being invoked is known based on static
type information, and this expression corresponds to one of the parameters
of the function being invoked, then return the parameter element
representing the parameter to which the value of this expression will be
bound. Otherwise, return
null
.no setterinherited - staticType → DartType?
-
Return the static type of this expression, or
null
if the AST structure has not been resolved.no setterinherited - typeArguments → TypeArgumentList?
-
Return the type arguments to be applied to the extension, or
null
if no type arguments were provided.no setter -
typeArgumentTypes
→ List<
DartType> ? -
Return the actual type arguments to be applied to the extension, either
explicitly specified in typeArguments, or inferred.
no setter
- unParenthesized → Expression
-
If this expression is a parenthesized expression, return the result of
unwrapping the expression inside the parentheses. Otherwise, return this
expression.
no setterinherited
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
ornull
if it cannot be found.inherited -
getProperty<
E> (String name) → E? -
Return the value of the property with the given
name
, ornull
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 -

name
to the givenvalue
. If the value isnull
, the property will effectively be removed.inherited -
thisOrAncestorMatching<
E extends AstNode> (bool predicate(AstNode)) → E? -
Return either this node or the most immediate ancestor of this node for
which the
predicate
returnstrue
, ornull
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.inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
