Constructor Detail

VariableAccessorVar0

public VariableAccessorVar0(RubyClass realClass,
                    String name,
                    int index,
                    int classId)

Construct a new StampedVariableAccessor for the given "real" class, variable name, variable index, and class ID.

Parameters:

realClass - the "real" class

name - the variable's name

index - the variable's index

classId - the class's ID

Method Detail

get

public Object get(Object object)

Retrieve the variable's value from the given object.

Overrides:

get in class VariableAccessor

Parameters:

object - the object from which to retrieve this variable

Returns:

the variable's value

set

public void set(Object object,
       Object value)

Set this variable into the given object using Unsafe to ensure safe updating of the variable table.

Overrides:

set in class VariableAccessor

Parameters:

object - the object into which to set this variable

value - the variable's value

setVariableChecked

public static void setVariableChecked(RubyBasicObject self,
                      RubyClass realClass,
                      int index,
                      Object value)

Set the given variable index into the specified object. The "real" class and index are pass in to provide functional access. This version checks if self has been frozen before proceeding to set the variable.

Parameters:

self - the object into which to set the variable

realClass - the "real" class for the object

index - the index of the variable

value - the variable's value

setVariable

public static void setVariable(RubyBasicObject self,
               RubyClass realClass,
               int index,
               Object value)

Set the given variable index into the specified object. The "real" class and index are pass in to provide functional access.

Parameters:

self - the object into which to set the variable

realClass - the "real" class for the object

index - the index of the variable

value - the variable's value
