Examples of QueryProcessor

com.google.gerrit.server.query.change.QueryProcessor
net.sf.saxon.query.QueryProcessor
A QueryProcessor allows the compilation of XQuery queries for subsequent execution. Compilation consists of parsing, static analysis, optimization, and creation of an internal representation of the query for subsequent evaluation.
The compilation of a query takes context information from a static context, which is represented by a StaticQueryContext object. This provides the necessary information about collations, base URI, etc.

This class is retained for backwards compatibility, but there is no longer any need for applications to use it directly, since all its methods are available directly from the StaticQueryContext object.
@deprecated since Saxon 8.1: use methods on the StaticQueryContext directly
org.jboss.dna.graph.query.process.QueryProcessor
An abstract {@link Processor} implementation that builds a tree of {@link ProcessingComponent} objects to perform the differentparts of the query processing logic. Subclasses are required to only implement one method: the {@link #createAccessComponent(QueryCommand,QueryContext,PlanNode,Columns,Analyzer)} should create a ProcessorComponentobject that will perform the (low-level access) query described by the {@link PlanNode plan} given as a parameter.
org.teiid.query.processor.QueryProcessor
Driver for plan processing.
org.wso2.carbon.registry.core.dataaccess.QueryProcessor
All query processors should extend this class. All configured query processor implementations will be associated with a query type. Once an execute operation is called for a query of that type, the associated query processor is invoked. Then all the tasks required for processing that query should be taken over by the query processor implementation. This processing steps include interpreting of given query parameters, constructing the resulting resource object, etc.
