CompilationUnit class abstract

A compilation unit.

While the grammar restricts the order of the directives and declarations within a compilation unit, this class does not enforce those restrictions. In particular, the children of a compilation unit will be visited in lexical order even if lexical order does not conform to the restrictions of the grammar.

compilationUnit ::= directives declarations

directives ::= ScriptTag? LibraryDirective? namespaceDirective* PartDirective* | PartOfDirective

namespaceDirective ::= ImportDirective | ExportDirective

declarations ::= CompilationUnitMember*

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

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
declarations → NodeList<CompilationUnitMember>
Return the declarations contained in this compilation unit.
no setter
declaredElement → CompilationUnitElement?
Return the element associated with this compilation unit, or null if the AST structure has not been resolved.
no setter
directives → NodeList<Directive>
Return the directives contained in this compilation unit.
no setter
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
featureSet → FeatureSet
The set of features available to this compilation unit.
no setter
hashCode → int
The hash code for this object.
no setterinherited
isSynthetic → bool
Return true if this node is a synthetic node.
no setterinherited
languageVersionToken → LanguageVersionToken?
The language version override specified for this compilation unit using a token like '// @dart = 2.7', or null if no override is specified.
no setter
length → int
Return the number of characters in the syntactic entity's source range.
no setterinherited
lineInfo → LineInfo?
Return the line information for this compilation unit.
no setter
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
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
scriptTag → ScriptTag?
Return the script tag at the beginning of the compilation unit, or null if there is no script tag in this compilation unit.
no setter
sortedDirectivesAndDeclarations → List<AstNode>
Return a list containing all of the directives and declarations in this compilation unit, sorted in lexical order.
no setter

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>(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.
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.
