IConditionFactory interface (structuredquery.h)
Provides methods for creating or resolving a condition tree that was obtained by parsing a query string.
Inheritance
The IConditionFactory interface inherits from the IUnknown interface. IConditionFactory also has these types of members:
Methods
The IConditionFactory interface has these methods.
| IConditionFactory::MakeAndOr Creates a condition node that is a logical conjunction (AND) or disjunction (OR) of a collection of subconditions. |
| IConditionFactory::MakeLeaf Creates a leaf condition node that represents a comparison of property value and constant value. |
| IConditionFactory::MakeNot Creates a condition node that is a logical negation (NOT) of another condition (a subnode of this node). (IConditionFactory.MakeNot) |
| IConditionFactory::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 demonstrates how to read lines from the console, parse them using the system schema, and display the resulting condition trees.
