Query and Related Classes

The following classes define arbitrary search methods and filter conditions, and provide methods for combining test criteria and dynamically querying result sets.

Query and Related Classes
Class	Description
Query	Defines arbitrary search methods and can be composed of search conditions, object/row state filter conditions, and data ordering information.
AttributeTest	Defines filter conditions for MBO attributes.
CompositeTest	Contains a method to combine test criteria using the logical operators AND, OR, and NOT to create a compound filter.
QueryResultSet	Provides for querying a result set for the dynamic query API.

In addition queries support select, where, and join statements.

Arbitrary Find
The arbitrary find method provides custom device applications the ability to dynamically build queries based on user input.
AttributeTest
An AttributeTest defines a filter condition using an MBO attribute, and supports conditions.
CompositeTest
A CompositeTest combines multiple TestCriteria using the logical operators AND, OR and NOT to create a compound filter.
QueryResultSet
The QueryResultSet class provides for querying a result set for the dynamic query API. QueryResultSet is returned as a result of executing a query.
