Method Detail

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

getTypeOfThis

public JSType getTypeOfThis()

Description copied from interface: StaticTypedScope

Specified by:

getTypeOfThis in interface StaticTypedScope<JSType>

getParentScope

public StaticTypedScope<JSType> getParentScope()

Description copied from interface: StaticTypedScope

Returns the scope enclosing this one or null if none.

Specified by:

getParentScope in interface StaticTypedScope<JSType>

Specified by:

getParentScope in interface StaticScope

getSlot

public SimpleSlot getSlot(java.lang.String name)

Description copied from interface: StaticTypedScope

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 StaticTypedScope<JSType>

Specified by:

getSlot in interface StaticScope

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 SimpleSlot getOwnSlot(java.lang.String name)

Description copied from interface: StaticTypedScope

Like getSlot but does not recurse into parent scopes.

Specified by:

getOwnSlot in interface StaticTypedScope<JSType>

Specified by:

getOwnSlot in interface StaticScope

getReferences

public java.lang.Iterable<PreprocessorSymbolTable.Reference> getReferences(SimpleSlot symbol)

getAllSymbols

public java.lang.Iterable<SimpleSlot> getAllSymbols()

Description copied from interface: StaticSymbolTable

Returns all variables in this symbol table.

Specified by:

getAllSymbols in interface StaticSymbolTable<SimpleSlot,PreprocessorSymbolTable.Reference>

getScope
