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.
