OEFuzzy

class OEFuzzy

This class represents OEFuzzy.

The OEFuzzy class represents fuzzy logic used in expression tests.

Constructors

OEFuzzy()

Default constructor.

OEFuzzy(const unsigned int v)

Construct an OEFuzzy object given with an integer value. The integer values should be one of the values give in the OEFuzzVal namespace. Three pre-defined global constant fuzzy values (OEChem_FzTrue, OEChem_FzFalse, and OEChem_FzMaybe) are define in OEChem which represent the fuzzy values of true, false, and maybe, respectively.

Default and copy constructors.

operator!

const OEFuzzy &operator!() const

Negation operator. Negation of true(OEChem_FzTrue) will return false(OEChem_FzFalse). Negation of false(OEChem_FzFalse) will return true(OEChem_FzTrue). Negation of maybe(OEChem_FzMaybe) will return maybe (OEChem_FzMaybe).

operator!=

bool operator!=(const OEFuzzy &) const

Not equal operator. Two OEFuzzy objects are not equivalent if their fuzzy logic values differ.

operator&&

const OEFuzzy &operator&&(const OEFuzzy &) const

And operator. Logic values for ‘’fuzzy and’’ is the following:

OEChem_FzFalse && OEChem_FzFalse	OEChem_FzFalse
OEChem_FzFalse && OEChem_FzMaybe	OEChem_FzFalse
OEChem_FzFalse && OEChem_FzTrue	OEChem_FzFalse
OEChem_FzMaybe && OEChem_FzFalse	OEChem_FzFalse
OEChem_FzMaybe && OEChem_FzMaybe	OEChem_FzMaybe
OEChem_FzMaybe && OEChem_FzTrue	OEChem_FzMaybe
OEChem_FzTrue && OEChem_FzFalse	OEChem_FzFalse
OEChem_FzTrue && OEChem_FzMaybe	OEChem_FzMaybe
OEChem_FzTrue && OEChem_FzTrue	OEChem_FzTrue

operator==

bool operator==(const OEFuzzy &) const

Equivalence operator. Two OEFuzzy objects are equivalent if their fuzzy logic values are identical.

operator||

const OEFuzzy &operator||(const OEFuzzy &) const

Or operator. Logic values for ‘’fuzzy or’’ is the following:

OEChem_FzFalse || OEChem_FzFalse	OEChem_FzFalse
OEChem_FzFalse || OEChem_FzMaybe	OEChem_FzMaybe
OEChem_FzFalse || OEChem_FzTrue	OEChem_FzTrue
OEChem_FzMaybe || OEChem_FzFalse	OEChem_FzMaybe
OEChem_FzMaybe || OEChem_FzMaybe	OEChem_FzMaybe
OEChem_FzMaybe || OEChem_FzTrue	OEChem_FzTrue
OEChem_FzTrue || OEChem_FzFalse	OEChem_FzTrue
OEChem_FzTrue || OEChem_FzMaybe	OEChem_FzTrue
OEChem_FzTrue || OEChem_FzTrue	OEChem_FzTrue

operator bool

operator bool() const

Boolean test operator. Both fuzzy true (OEChem_FzTrue) and maybe (OEChem_FzMaybe) values will return true. A fuzzy false(OEChem_FzFalse) value will return false.
