fastGetInstanceVariable

IRubyObject fastGetInstanceVariable(java.lang.String internedName)

Returns the named instance variable if present, else null. The supplied name must have been previously interned.

Parameters:

internedName - the interned name of an instance variable

Returns:

he named instance variable if present, else null

setInstanceVariable

Parameters:

internedName - the interned name of an instance variable

value - the value to be set

removeInstanceVariable

IRubyObject removeInstanceVariable(java.lang.String name)

Removes the named instance variable, if present, returning its value.

Parameters:
