FourVarDynamicScope

public FourVarDynamicScope(StaticScope staticScope,
                   DynamicScope parent)

FourVarDynamicScope

public FourVarDynamicScope(StaticScope staticScope)

Method Detail

growIfNeeded

public void growIfNeeded()

Overrides:

growIfNeeded in class ThreeVarDynamicScope

cloneScope

public DynamicScope cloneScope()

Overrides:

cloneScope in class ThreeVarDynamicScope

getValues

public IRubyObject[] getValues()

Overrides:

getValues in class ThreeVarDynamicScope

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.

Overrides:

getValue in class ThreeVarDynamicScope

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

getValueOrNil

public IRubyObject getValueOrNil(int offset,
                        int depth,
                        IRubyObject nil)

Variation of getValue that checks for nulls, returning and setting the given value (presumably nil)

Overrides:

getValueOrNil in class ThreeVarDynamicScope

getValueDepthZeroOrNil

public IRubyObject getValueDepthZeroOrNil(int offset,
                                 IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for depth 0

Overrides:

getValueDepthZeroOrNil in class ThreeVarDynamicScope

getValueThreeDepthZeroOrNil

public IRubyObject getValueThreeDepthZeroOrNil(IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for index 3, depth 0

Overrides:

getValueThreeDepthZeroOrNil in class NoVarsDynamicScope

setValue

public IRubyObject setValue(int offset,
                   IRubyObject value,
                   int depth)

Set value in current dynamic scope or one of its captured scopes.

Overrides:

setValue in class ThreeVarDynamicScope

Parameters:

offset - zero-indexed value that represents where variable lives

value - to set

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

setValueDepthZero

public IRubyObject setValueDepthZero(IRubyObject value,
                            int offset)

Description copied from class: DynamicScope

setValue for depth zero

Overrides:

setValueDepthZero in class ThreeVarDynamicScope

Parameters:

value - to set

offset - zero-indexed value that represents where variable lives

setValueThreeDepthZero

public IRubyObject setValueThreeDepthZero(IRubyObject value)

Description copied from class: DynamicScope

Set value three in this scope.

Overrides:

setValueThreeDepthZero in class NoVarsDynamicScope
