Constructor Detail

SharedBindingDynamicScope

public SharedBindingDynamicScope(StaticScope staticScope,
                         IRMethod irMethod)

Method Detail

cloneScope

public DynamicScope cloneScope()

Specified by:

cloneScope in class DynamicScope

getValues

public IRubyObject[] getValues()

Specified by:

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

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)

Specified by:

getValueOrNil in class DynamicScope

getValueDepthZeroOrNil

public IRubyObject getValueDepthZeroOrNil(int offset,
                                 IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for depth 0

Specified by:

getValueDepthZeroOrNil in class DynamicScope

getValueZeroDepthZeroOrNil

public IRubyObject getValueZeroDepthZeroOrNil(IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for index 0, depth 0

Specified by:

getValueZeroDepthZeroOrNil in class DynamicScope

getValueOneDepthZeroOrNil

public IRubyObject getValueOneDepthZeroOrNil(IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for index 1, depth 0

Specified by:

getValueOneDepthZeroOrNil in class DynamicScope

getValueTwoDepthZeroOrNil

public IRubyObject getValueTwoDepthZeroOrNil(IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for index 2, depth 0

Specified by:

getValueTwoDepthZeroOrNil in class DynamicScope

getValueThreeDepthZeroOrNil

public IRubyObject getValueThreeDepthZeroOrNil(IRubyObject nil)

Description copied from class: DynamicScope

getValueOrNil for index 3, depth 0

Specified by:

getValueThreeDepthZeroOrNil in class DynamicScope

setValue

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

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

Specified by:

setValue in class DynamicScope

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

Specified by:

setValueDepthZero in class DynamicScope

Parameters:

value - to set

offset - zero-indexed value that represents where variable lives

setValueZeroDepthZero

public IRubyObject setValueZeroDepthZero(IRubyObject value)

Description copied from class: DynamicScope

Set value zero in this scope;

Specified by:

setValueZeroDepthZero in class DynamicScope

setValueOneDepthZero

public IRubyObject setValueOneDepthZero(IRubyObject value)

Description copied from class: DynamicScope

Set value one in this scope.

Specified by:

setValueOneDepthZero in class DynamicScope

setValueTwoDepthZero

public IRubyObject setValueTwoDepthZero(IRubyObject value)

Description copied from class: DynamicScope

Set value two in this scope.

Specified by:

setValueTwoDepthZero in class DynamicScope

setValueThreeDepthZero

public IRubyObject setValueThreeDepthZero(IRubyObject value)

Description copied from class: DynamicScope

Set value three in this scope.

Specified by:

setValueThreeDepthZero in class DynamicScope

growIfNeeded

public void growIfNeeded()

Make a larger dynamic scope if the static scope grew. Eval's with bindings require us to possibly change the size of the dynamic scope if things like 'eval "b = 2", binding' happens.

Specified by:

growIfNeeded in class DynamicScope
