Detailed Description

Ephemeral random integer constant.

This is like real::real but restricted to integer numbers.

Definition at line 97 of file real.h.

Constructor & Destructor Documentation

integer()

vita::real::integer::integer ( const cvect &  c, int  m = -128, int  u = 127  )

inlineexplicit

Definition at line 100 of file real.h.

Member Function Documentation

display()

std::string vita::real::integer::display ( terminal_param_t  v, format    ) const

inlinefinalvirtual

Parameters

[in]

v

additional informations regarding parametric symbols

Returns

a string representing the symbol

The v argument is required for parametric symbols (i.e. for a numeric terminal we have to print 123 rather than "NUMBER").

Reimplemented from vita::terminal.

Definition at line 111 of file real.h.

eval()

value_t vita::real::integer::eval ( symbol_params &  ) const

inlinefinalvirtual

Calculates the value of / performs the action associated with the symbol (it's implementation specific).

Implements vita::symbol.

Definition at line 114 of file real.h.

init()

terminal_param_t vita::real::integer::init ( ) const

inlinefinalvirtual

Used to initialize the internal parameter of the terminal.

Returns

0.0

Remarks

Derived classes should redefine this member function in a meaningful way.

Reimplemented from vita::terminal.

Definition at line 109 of file real.h.

parametric()

bool vita::real::integer::parametric ( ) const

inlinefinalvirtual

A parametric terminal needs an additional parameter to be evaluated.

Returns

true for parametric symbols

Genes associated with parametric symbols store an additional parameter fetched at run-time and used for symbol evaluation.

Reimplemented from vita::terminal.

Definition at line 107 of file real.h.
