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.

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:
