Properties

beginToken Token
Return the first token included in this node's source range.
read-only
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.
read-only
end → int
Return the offset of the character immediately following the last character of this node's source range. [...]
read-only, override
endToken Token
Return the last token included in this node's source range.
read-only
isSynthetic → bool
Return true if this node is a synthetic node. [...]
read-only
length → int
Return the number of characters in the syntactic entity's source range.
read-only, override
offset → int
Return the offset from the beginning of the file to the first character in the syntactic entity.
read-only, override
parent AstNode
Return this node's parent node, or null if this node is the root of an AST structure. [...]
read-only
root AstNode
Return the node at the root of this node's AST structure. [...]
read-only
hashCode → int

Methods

accept<E>(AstVisitor<E> visitor) → E
Use the given visitor to visit this node. [...]
findPrevious(Token target) Token
Return the token before target or null if it cannot be found.
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.
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.
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.
thisOrAncestorOfType<T extends AstNode>() → T
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.
toSource() → String
Return a textual description of this node in a form approximating valid source. [...]
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node. [...]
noSuchMethod(Invocation invocation) → dynamic

inherited
toString() → String
Returns a string representation of this object.
