IConditionFactory Interface

Provides methods for creating or resolving a condition tree that was obtained by parsing a query string.

IConditionFactory Members

MakeAndOr	Creates a condition node that is a logical conjunction (AND) or disjunction (OR) of a collection of subconditions.
MakeLeaf	Creates a leaf condition node that represents a comparison of property value and constant value.
MakeNot	Creates a condition node that is a logical negation (NOT) of another condition (a subnode of this node).
Resolve	Performs a variety of transformations on a condition tree, including the following: resolves conditions with relative date/time expressions to conditions with absolute date/time (as a VT_FILETIME); turns other recognized named entities into condition trees with actual values; simplifies condition trees; replaces virtual or compound properties with OR trees of other properties; removes condition trees resulting from queries with property keywords that had no condition applied.

Remarks

The StructuredQuerySample code sample, available on Code Gallery and the Windows 7 SDK, demonstrates how to read lines from the console, parse them using the system schema, and display the resulting condition trees.
