Constructors
- IfStatementImpl({required Token ifKeyword, required Token leftParenthesis, required ExpressionImpl condition, required CaseClauseImpl? caseClause, required Token rightParenthesis, required StatementImpl thenStatement, required Token? elseKeyword, required StatementImpl? elseStatement})
-
Initialize a newly created if statement. The elseKeyword and
elseStatement
can benull
if there is no else clause.
Properties
- beginToken → Token
-
Return the first token included in this node's source range.
no setteroverride
- caseClause → CaseClauseImpl?
-
Return the
case
clause used to match a pattern against the condition.final -
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
- condition ↔ ExpressionImpl
-
Return the condition used to determine which of the statements is executed
next.
getter/setter pairoverride-getter
- elseKeyword → Token?
-
Return the token representing the 'else' keyword, or
null
if there is no else statement.final - elseStatement ↔ StatementImpl?
-
Return the statement that is executed if the condition evaluates to
false
, ornull
if there is no else statement.getter/setter pairoverride-getter - 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 setteroverride
- expression → ExpressionImpl
-
Return the expression used to either determine which of the statements is
executed next or to compute the value matched against the pattern in the
case
clause.no setteroverride - hashCode → int
-
The hash code for this object.
no setterinherited
- ifFalse → StatementImpl?
-
The node that is executed if the condition evaluates to
false
.no setteroverride - ifKeyword → Token
-
Return the token representing the 'if' keyword.
TODO(scheglov) Extract shared
IfCondition
, see the patterns spec.final - ifTrue → StatementImpl
-
The node that is executed if the condition evaluates to
true
.no setteroverride - isSynthetic → bool
-
Return
true
if this node is a synthetic node.no setterinherited - leftParenthesis → Token
-
Return the left parenthesis.
final
- length → int
-
Return the number of characters in the syntactic entity's source range.
no setterinherited
-
namedChildEntities
→ Iterable<
ChildEntity> -
Return properties (tokens and nodes) of this node, with names, in the
order in which these entities should normally appear, not necessary in
the order they really are (because of recovery).
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 - rightParenthesis → Token
-
Return the right parenthesis.
final
- 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
- thenStatement ↔ StatementImpl
-
Return the statement that is executed if the condition evaluates to
true
.getter/setter pairoverride-getter - unlabeled → StatementImpl
-
If this is a labeled statement, return the unlabeled portion of the
statement, otherwise return the statement itself.
no setterinherited
