TwoVarDynamicScope

public TwoVarDynamicScope(StaticScope staticScope)

Method Detail

growIfNeeded

public void growIfNeeded()

Overrides:

growIfNeeded in class OneVarDynamicScope

cloneScope

public DynamicScope cloneScope()

Overrides:

cloneScope in class OneVarDynamicScope

getValues

public IRubyObject[] getValues()

Overrides:

getValues in class OneVarDynamicScope

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 OneVarDynamicScope

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

getValueDepthZeroOrNil

public IRubyObject getValueDepthZeroOrNil(int offset,
                                 IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for depth 0

Overrides:

getValueDepthZeroOrNil in class OneVarDynamicScope

getValueOneDepthZeroOrNil

public IRubyObject getValueOneDepthZeroOrNil(IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for index 1, depth 0

Overrides:

getValueOneDepthZeroOrNil 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 OneVarDynamicScope

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 OneVarDynamicScope

Parameters:

value - to set

offset - zero-indexed value that represents where variable lives

setValueOneDepthZero

public IRubyObject setValueOneDepthZero(IRubyObject value)

Description copied from class: DynamicScope

Set value one in this scope.

Overrides:

setValueOneDepthZero in class NoVarsDynamicScope
