69 CQLExpressions:
70 For an expression, CQLExpression::getValue is called and will return a
71 CQLValue.
72 The appropriate operator is then invoked on CQLValue and that operator
73 function will
74 enforce the type restrictions as documented in the DMTF CQL
75 Specification.
76 That operator then determines whether the predicate is TRUE / FALSE.

79 CQLPredicates:
80 The CQLPredicate is non-terminal if it contains only CQLPredicate
81 objects.
82 A non-terminal CQLPredicate is evaluated by in turn evaluating the
83 contained CQLPredicates and
84 boolean operator.
85 Valid operators are:
86 AND, OR
87 humberto 1.1.2.1
88 For the evaluate method on each CQLPredicate. the CQLPredicate is
89 evaluated to TRUE/FALSE and
90 the result of the evaluation is then applied to the appropriate boolean
91 operator.
92
93 The result of the evaluation is and then inverted if the _invert member
94 variable is set to TRUE
95 and then returned to the caller.
