Interface StaticTypedScope

All Superinterfaces:

StaticScope

All Known Subinterfaces:

FlowScope

All Known Implementing Classes:

TypedScope

public interface StaticTypedScope
extends StaticScope

The StaticTypedScope interface must be implemented by any object that defines variables for the purposes of static analysis. It is distinguished from the Scriptable class that Rhino normally uses to represent a run-time scope.

Method Summary

Modifier and Type	Method and Description
StaticTypedSlot	getOwnSlot(java.lang.String name) Like getSlot but does not recurse into parent scopes.
StaticTypedScope	getParentScope() Returns the scope enclosing this one or null if none.
StaticTypedSlot	getSlot(java.lang.String name) Returns any defined slot within this scope for this name.
JSType	getTypeOfThis() Returns the expected type of this in the current scope.
default JSType	lookupQualifiedName(QualifiedName qname) Looks up a given qualified name in the scope.

Method Detail

getParentScope

StaticTypedScope getParentScope()

Returns the scope enclosing this one or null if none.

Specified by:

getParentScope in interface StaticScope

getSlot

StaticTypedSlot getSlot(java.lang.String name)

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

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

StaticTypedSlot getOwnSlot(java.lang.String name)

Like getSlot but does not recurse into parent scopes.

Specified by:

getOwnSlot in interface StaticScope

getTypeOfThis

JSType getTypeOfThis()

Returns the expected type of this in the current scope.

lookupQualifiedName

@Nullable
default JSType lookupQualifiedName(QualifiedName qname)

Looks up a given qualified name in the scope. if that fails, looks up the component properties off of any owner types that are in scope.

This is always more or equally expensive as calling getSlot(String name), so should only be used when necessary.
