PrefixExpression class abstract
A prefix unary expression.
prefixExpression ::= Token Expression
Clients may not extend, implement or mix-in this class.
Constructors
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
- 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 - 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
- nullShortingTermination → Expression
-
Returns the expression that terminates any null shorting that might occur
in this expression. This may be called regardless of whether this
expression is itself null-aware.
no setterinherited
- offset → int
-
Return the offset from the beginning of the file to the first character in
the syntactic entity.
no setterinherited
- operand → Expression
-
Return the expression computing the operand for the operator.
no setter
- operator → Token
-
Return the prefix operator being applied to the operand.
no setter
- 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
- readElement → Element?
-
The element that is used to read the value.
no setterinherited
- readType → DartType?
-
The type of the value read with the readElement.
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 → MethodElement?
-
Return the element associated with the expression based on the static
types, or
null
if the AST structure has not been resolved, or there is no meaningful static element to return (e.g. because this is a non-compound assignment expression, or because the method referred to could not be resolved).no setterinherited - 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 - 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
- writeElement → Element?
-
The element that is used to write the result.
no setterinherited
- writeType → DartType?
-
The types of assigned values must be subtypes of this type.
no setterinherited
Methods
-
accept<
E> (AstVisitor< E> visitor) → E? -
Use the given
visitor

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 -

Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
setProperty(
String name, Object? value) → void -

. 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 -

source.
inherited
