CascadeExpression class abstract

A sequence of cascaded expressions: expressions that share a common target.

There are three kinds of expressions that can be used in a cascade expression: IndexExpression, MethodInvocation and PropertyAccess.

cascadeExpression ::= Expression cascadeSection*

cascadeSection ::= ('..' | '?..') (cascadeSelector arguments*) (assignableSelector arguments*)* (assignmentOperator expressionWithoutCascade)?

cascadeSelector ::= ' ' expression ' ' | identifier

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

CascadeExpression()

Properties

beginToken → Token
Return the first token included in this node's source range.
no setterinherited
cascadeSections → NodeList<Expression>
Return the cascade sections sharing the common target.
no setter
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
isNullAware → bool
Whether this cascade 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
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
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
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
target → Expression
Return the target of the cascade sections.
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 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>(bool predicate(AstNode)) → 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.
