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(java.lang.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(java.lang.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(java.lang.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 java.lang.String toString()

Overrides:

toString in class java.lang.Object
