getIndexOfSymbol

public int getIndexOfSymbol(SymbolTable.Symbol sym)
Gets a unique index for the symbol in this scope.

getRootNode

public Node getRootNode()
Description copied from interface: StaticScope
Returns the root node associated with this scope. May be null.

Specified by:
getRootNode in interface StaticScope<JSType>

getParentScope

public SymbolTable.SymbolScope getParentScope()
Description copied from interface: StaticScope
Returns the scope enclosing this one or null if none.

Specified by:
getParentScope in interface StaticScope<JSType>

getQualifiedSlot

public SymbolTable.Symbol getQualifiedSlot(String name)
Get the slot for a fully-qualified name (e.g., "a.b.c") by trying to find property scopes at each part of the path.

getSlot

public SymbolTable.Symbol getSlot(String name)
Description copied from interface: StaticScope
Returns any defined slot within this scope for this name. This call continues searching through parent scopes if a slot with this name is not found in the current scope.

Specified by:
getSlot in interface StaticScope<JSType>
Parameters:
name - The name of the variable slot to look up.
Returns:
The defined slot for the variable, or null if no definition exists.

getOwnSlot

public SymbolTable.Symbol getOwnSlot(String name)
Description copied from interface: StaticScope
Like getSlot but does not recurse into parent scopes.

Specified by:
getOwnSlot in interface StaticScope<JSType>

getTypeOfThis

public JSType getTypeOfThis()
Description copied from interface: StaticScope
Returns the expected type of this in the current scope.

Specified by:
getTypeOfThis in interface StaticScope<JSType>

isGlobalScope

public boolean isGlobalScope()

isDocScope

public boolean isDocScope()
Returns whether this is a doc scope. A doc scope is a table for symbols that are documented solely within a JSDoc comment.

isPropertyScope

public boolean isPropertyScope()

isLexicalScope

public boolean isLexicalScope()

getScopeDepth

public int getScopeDepth()

toString

public String toString()
Overrides:
