Method Detail

growIfNeeded

public void growIfNeeded()

Specified by:

growIfNeeded in class DynamicScope

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

                            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

setArgValues

public void setArgValues(IRubyObject[] values,
                         int size)

Set all values which represent 'normal' parameters in a call list to this dynamic scope. Function calls bind to local scopes by assuming that the indexes or the arg list correspond to that of the local scope (plus 2 since $_ and $~ always take the first two slots). We pass in a second argument because we sometimes get more values than we are expecting. The rest get compacted by original caller into rest args.

Specified by:

setArgValues in class DynamicScope

Parameters:

values - up to size specified to be mapped as ordinary parm values

size - is the number of values to assign as ordinary parm values

getArgValues

public IRubyObject[] getArgValues()

Description copied from class: DynamicScope

Copy variable values back for ZSuper call.

Specified by:

getArgValues in class DynamicScope

toString

public java.lang.String toString(java.lang.StringBuffer buf,
                                 java.lang.String indent)

Specified by:

toString in class DynamicScope
