Documentation

The EST_Val class is a container class, used to store a single item which can be an int, float, string or other user-defined class. It is often used as the base item in the <link linkend="est-features">EST_Features</link> class, to enable features to take on values of different types.

Constructor and Destructor functions

EST_Val()

Default constructor

EST_Val(const EST_Val &val)

Copy constructor for another EST_Val

EST_Val(const int i)

Getting cast values

const val_type type(void) const

returns the type that the val is currently holding

const int Int(void) const

returns the value, cast as an int

const int I(void) const

const float Float(void) const

returns the value, cast as an float

const float F(void) const

returns the value, cast as an float

const EST_String& String(void) const

returns the value, cast as an string

const EST_String& string(void) const

returns the value, cast as an string

const EST_String& S(void) const

returns the value, cast as an string

const EST_String& string_only(void) const

returns the value, cast as an string

Setting values

EST_Val& operator=(const int i)

Assignment of val to an int

EST_Val& operator=(const float f)

EST_Val& operator=(const EST_String &s)

Assignment of val to a string

EST_Val& operator=(const char* s)

Assignment of val to a string literal

EST_Val& operator=(const EST_Val &c)
