Interface StaticScope

All Known Subinterfaces:
FlowScope, StaticTypedScope
All Known Implementing Classes:
AbstractScope, Scope, TypedScope
public interface StaticScope
The StaticScope 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 Details

    • getRootNode

      Node getRootNode()
      Returns the root node associated with this scope. May be null.

    • getParentScope

      StaticScope getParentScope()
      Returns the scope enclosing this one or null if none.

    • getSlot

      StaticSlot getSlot(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.
      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

      StaticSlot getOwnSlot(String name)
      Like getSlot but does not recurse into parent scopes.

    • getTopmostScopeOfEventualDeclaration

      default @Nullable StaticScope getTopmostScopeOfEventualDeclaration(String name)
      Returns the topmost slot containing this name, or null if no slots do. May return true in cases where getSlot(java.lang.String) returns null, though. Do not rely on this method if you need an actual slot.

      This method is intended for use while scopes are still being built, hence the name 'eventual' declaration. Once scope building is complete, the scope returned from this method must be equivalent to "getSlot(name).getScope()" or null
