Returns the logical value FALSE.

TRUE

public static Boolean TRUE()

Returns the logical value TRUE.

NOT

public static Boolean NOT(Boolean boolValue)

Returns the negation of the specified boolean expression.

OR

public static Boolean OR(Boolean... arguments)

Returns true if any of the arguments is considered true, false otherwise. Argument must be a logical result or a direct boolean value.

IF

public static Object IF(Boolean test,
                        Object value1,
                        Object value2)

Returns one of two values, depending on a test condition.
