    Description copied from class: PSObject
    
    Executes PostScript object. For literal objects this execution means pushing object to operand stack, for operator and procedure objects execution mean execution of this operator or procedure.
    
    Specified by:
    
    execute in class PSObject
    
    Parameters:
    
    operandStack - is stack for PostScript operands (see PostScript specification for further information).
    
    userDict - is a dictionary that stores all key-value associated pair encountered during PostScript parsing. Full PostScript parser needs a dict stack, our implementation has only one dictionary.
    
    Throws:
    
    PostScriptException
