Constructor Details

Symbol

public Symbol()

Symbol

public Symbol(Symbol.Type declType,
 String name)

Constructs a new Symbol with a specific name and declaration type

Parameters:

declType - Token.FUNCTION, Token.LP (for params), Token.VAR, Token.LET or Token.CONST

Method Details

getDeclType

public Symbol.Type getDeclType()

Returns symbol declaration type

setDeclType

public void setDeclType(Symbol.Type declType)

Sets symbol declaration type

getName

public String getName()

Returns symbol name

setName

public void setName(String name)

Sets symbol name

getNode

public Node getNode()

Returns the node associated with this identifier

getIndex

public int getIndex()

Returns symbol's index in its scope

setIndex

public void setIndex(int index)

Sets symbol's index in its scope

setNode

public void setNode(Node node)

Sets the node associated with this identifier

getContainingTable

public Scope getContainingTable()

Returns the Scope in which this symbol is entered

setContainingTable

public void setContainingTable(Scope containingTable)

Sets this symbol's Scope

getDeclaredScope

public Scope getDeclaredScope()

Returns the lexical scope in which this symbol was declared, or null if not set. For VAR symbols this is the block scope containing the declaration, which may differ from getContainingTable() (the enclosing function/script to which the var is hoisted).

setDeclaredScope

public void setDeclaredScope(Scope declaredScope)

Sets the lexical scope in which this symbol was declared.

getDeclTypeName

public String getDeclTypeName()

isDeclTypeLexical

public boolean isDeclTypeLexical()

isDeclTypeLexical

public static boolean isDeclTypeLexical(Symbol.Type declType)

toString

public String toString()

Overrides:

toString in class Object
