All Implemented Interfaces:

Cloneable

public class ManyVarsDynamicScope
extends DynamicScope

Represents the the dynamic portion of scoping information. The variableValues are the values of assigned local or block variables. The staticScope identifies which sort of scope this is (block or local). Properties of Dynamic Scopes: 1. static and dynamic scopes have the same number of names to values 2. size of variables (and thus names) is determined during parsing. So those structured do not need to change FIXME: When creating dynamic scopes we sometimes accidentally pass in extra parents. This is harmless (other than wasting memory), but we should not do that. We can fix this in two ways: 1. Fix all callers 2. Check parent that is passed in and make if new instance is local, then its parent is not local

Method Details

setVariableValues

public void setVariableValues(IRubyObject[] variableValues)

getValues

public IRubyObject[] getValues()

Overrides:

getValues in class DynamicScope

getValue

public IRubyObject getValue(int offset,
 int depth)

Get value from current scope or one of its captured scopes. FIXME: block variables are not getting primed to nil so we need to null check those until we prime them properly. Also add assert back in.

Specified by:

getValue in class DynamicScope

Parameters:

offset - zero-indexed value that represents where variable lives

depth - how many captured scopes down this variable should be set

Returns:

the value here
