Constructor Detail

IdentifierTreeImpl

public IdentifierTreeImpl(Tree.Kind kind,
                          InternalSyntaxToken nameToken)

Method Detail

getKind

public Tree.Kind getKind()

Specified by:

getKind in class JavaScriptTree

identifierToken

public SyntaxToken identifierToken()

Specified by:

identifierToken in interface IdentifierTree

name

public String name()

Specified by:

name in interface IdentifierTree

toString

public String toString()

Overrides:

toString in class JavaScriptTree

symbolUsage

public Optional<Usage> symbolUsage()

Specified by:

symbolUsage in interface IdentifierTree

Returns:

Usage corresponding to this identifier. Empty optional is returned when there is no symbol available for this identifier (see IdentifierTree.symbol())

symbol

public final Optional<Symbol> symbol()

Specified by:

symbol in interface IdentifierTree

Returns:

Symbol which is referenced by this identifier. No Symbol is returned in several cases:

• for Tree.Kind.PROPERTY_IDENTIFIER
• for unresolved symbol (i.e. symbol being read without being written)

Note that Tree.Kind.BINDING_IDENTIFIER (used for symbol declaration) always has corresponding symbol. Note that this method is a shortcut for {@link IdentifierTree#symbolUsage()#symbol()}.

setSymbolUsage

public void setSymbolUsage(Usage usage)

types

public TypeSet types()

Description copied from interface: ExpressionTree

Returns an unmodifiable set of the possible types for the expression. Attempts to modify the returned set, whether direct or via its iterator, will result in an UnsupportedOperationException.

Specified by:

types in interface ExpressionTree

add

public void add(Type type)

Specified by:

add in interface TypableTree

childrenIterator

public Iterator<Tree> childrenIterator()

Description copied from class: JavaScriptTree

Creates iterator for children of this node. Note that iterator may contain null elements.

Specified by:

childrenIterator in class JavaScriptTree

accept

public void accept(DoubleDispatchVisitor visitor)

Specified by:

accept in interface Tree

scope

public Scope scope()

Specified by:

scope in interface IdentifierTree

Returns:

Scope instance in which this identifier appear

scope

public void scope(Scope scope)

bindingIdentifiers

public List<IdentifierTree> bindingIdentifiers()

Specified by:

bindingIdentifiers in interface BindingElementTree
