Inheritance:

Public Methods
virtual adlib_real get_false_val( void ): Get the value representing false
virtual adlib_real get_true_val( void ): Get the value representing true
virtual bool is_false( const adlib_real val ): Test if the value is false
virtual bool is_true( const adlib_real val ): Test if the value is true
logic_base( const string& name_arg, const module* parent_arg, const string& mod_type, size_t inputs ): Constructor of logic_base class
virtual void sub_sub_load( void ): When setting parameters are updated, sub_sub_load sets default values of all the inputs
~logic_base( void ): Destructor

Protected Fields
adlib_real false_val: Numerical value representing false
adlib_real threshold: Threshold of the logic test, if val > threshold, then true
adlib_real true_val: Numerical value representing true

Documentation

logic_base is the base class of logic modules.
logic modules accept type of real inputs and each module generates an output of type real. An input value is TRUE if input > "threshold". When an output represents a logical true or false, numerical values "true_val" and "false_val" are used for each state. The preset values for these parameters are as follows and they can be chaged as settings. threshold = 0.9, true_val = 5, false_val = 0.

logic_base( const string& name_arg, const module* parent_arg, const string& mod_type, size_t inputs )

Constructor of logic_base class.

Constructor registers three parameters, threshold, true_val and false_val, and sets defaul values of all inputs to true_val.

Parameters:: name_arg - the name of the module (e.g., "logic_board_No1")
parent_arg - the pointer to the parent module, usually a box.
module_type - the name of the module type (e.g., "and", "or")
inputs - number of inputs to this module
