Using the Canonize Methods

The following methods are useful for providers that pass the WQL query string to another entity that parses the string:

• canonizeDOC - Canonizes the expression into a Disjunction of Conjunctions form. (OR of ANDed comparison expressions). This enables handling of the expression as a List of Lists rather than a tree form, enabling ease of evaluation. For example: (x > 5 and y > 6) or (y > 6 and z=7)

• canonizeCOD - Canonizes the expression into a Conjunction of Disjunctions form. (AND of ORed comparison expressions). This enables handling of the expression as a List of Lists rather than a tree form, enabling ease of evaluation. For example: (x > 5 or y > 6) and (y > 6 or z=7)
